Here, we analyzed the colluvial deposits located on the rim of the Serra Geral escarpments in the Paraná Basin to propose a model with an absolute age range of minor landform evolution within this cuesta morphology. Correlation of the optically stimulated luminescence ages with the regional paleoclimatic conditions demonstrates that the successive phases of colluviation reflect either short-term intervals of variability in moisture availability or dry periods in the Holocene. The potential effects of other contributing factors (vegetation changes, local geomorphic settings and human activity) add complexity to the denudation responsible for the development of the investigated geomorphic chronosequences. The proposed model consists of five stages of hillslope sediment remobilization that were responsible for further remodeling of the minor vertical steps during the following chronological distribution: (i) 9.13 ± 1.2–7.09 ± 0.96 ka; (ii) 5.66 ± 0.86–4.5 ± 0.75 ka; (iii) 3.94 ± 0.605–3.45 ± 0.6 ka; (iv) 2.66 ± 0.315–2.3 ± 0.4 ka; and (v) after 1960 to the present day.

Ordovician limestone and Cambrian dolomite are the main oil and gas producing layers in eastern Tazhong field, Tarim basin. Industrial oil flow has been obtained from drilling in this zone, proving that the Lower Paleozoic strata is important for oil and gas exploration and development. However, the main controlling factors and distribution of high-quality reservoirs remain unclear. Based on the logging constrained seismic inversion , FMI (Fullbore Formation MicroImager) log interpretation and core analysis of six wells, the main controlling factors of Paleozoic carbonate reservoirs in the study area were investigated. The results reveal that the two buried cuestas control the distribution of the Cambrian and Ordovician strata, the ratio of mudstone in north buried cuesta (NBC) is more than that in south buried cuesta (SBC), and the average porosity of 3xq dolomite formation is more than that of O 1 − 2 y limestone formation. FMI logging interpretation results show that fracture density of well TZ-1 is significantly higher than that of well TZ-2, combined with core observation and microscopic analysis we can believe that reconstructed dolomite reservoir has developed dissolution pores and vugs. By the means of seismic impedance reconstruction, the most favorable production areas, so-called sweet-spots, are karst residual mounds that formed independent small anticlinal high points and have been depicted. Finally, total 28 traps in the Cambrian–Ordovician​ carbonate buried hill are characterized, covering an area of 66.4 km2. 17 anticline traps with an area of 26.9 km2 in dolomite reservoirs are optimized to be the next exploration targets.

La identificación de los nombres de los oppida del final de la Edad del Hierro ha despertado el interés de los historiadores y arqueólogos desde la Plena Edad Media. A lo largo de los siglos, especialmente en los últimos doscientos años, han sido numerosas las propuestas por ubicar en localidades y yacimientos concretos los topónimos de ciudades prerromanas y romanas citadas por las fuentes griegas y romanas y por los documentos epigráficos. En este artículo abordamos los casos de tres yacimientos de la provincia de Soria que se han vinculado con diferentes oppida celtibéricos y ciudades romanas, sin tener, en ocasiones, los suficientes argumentos para ello: Medinaceli, identificado tradicionalmente con Ocilis y, en las últimas décadas, también con Cortona y Segontia; las Ruinas Ciclópeas de Santa María de Huerta y Granja de San Pedro, donde se ha situado la Arcobriga prerromana; Las Quintanas-La Cuesta del Moro de Langa de Duero vinculado, desde su descubrimiento y excavación por Blas de Taracena, con Segontia Lanca.

A new infaunal pinnotherid crab, Pinnixulala heardin. sp., is described from muddy substrates of the middle to inner continental shelf of the northern Gulf of Mexico. Molecular genetic analysis supports its separation from P. retinens (Rathbun, 1918), the only other western Atlantic member of the genus and a species most commonly found living as a symbiont of large polychaete worms. Both western Atlantic species are clearly separated from several described and undescribed populations of congeners occurring along shorelines of the eastern Pacific. We herein include a rediagnosis of P. retinens to facilitate morphological comparisons with P. heardin. sp. Unlike P. retinens, which is more common in shallow inshore waters and reaches larger sizes, the new species lacks development of a strong distally directed spine on the fourth pereopod ischium and has chelae that are at least as heavily developed as the second and third pereopods. In addition, the mature male first gonopods in P. heardin. sp. are tapered over their terminal one-third and directed distally, rather than being curved in their terminal one-third with the tips directed mesially, as they are in P. retinens. The new species is invariably collected from samples including infaunal worms and other invertebrates, but the specific hosts remain to be determined

The Parana Volcanic Province follows Siberia as the second largest in the continents and offers a unique opportunity to study the hydrothermal relationship between basalt-rhyodacite lavas and buried erg-turned aquifer in an intraplate setting. Injected sand fluidized after basalt sealing and was succeeded by amethyst and agate geode opening and filling. Excellent exposures in the Herveiras cuesta, southern Brazil, allow the comparison of processes over long distances (1500 km) in the volcanic group. Fieldwork and basalt chemistry led to the identification of three hydrothermal processes-amygdales filling (H1), sand injection (H2) and amethyst geodes formation (H3). Sand injection was triggered by high temperature (150 ℃) and seismicity. These low-temperature processes identified in the Herveiras cuesta demonstrate the homogeneity of relationships between the paleoerg, giant aquifer and intraplate volcanic rocks across the volcanic province.

They are habitually studied in many regions of the world. In Brazil, however, studies of erosion processes in cuestas are uncommon, despite the presence of this type of relief in several parts of the country. The aim of this study was to identify relevant correlations between local geographical conditions and physical-hydrological properties of the soil, and to identify the prevailing factors in the development of rill erosion, ravines and gullies in cuestas. We analyze various physical properties of the soil, including grain size, resistance to penetration, permeability and infiltration rates. The geographic variable slope was also considered. The data variables were processed using geostatistical techniques (ordinary kriging) and statistics (factor analysis). The results show that data referring to grain size, soil resistance to penetration and infiltration present statistically significant differences and can be used to assess the spatial distribution of erosion landforms. Details of the behavior of clays and the transitions between the clayey and sandy sector also helped to understand the location of erosion landforms. The steep morphology of the cuestas, associated with the presence of lithologies of varying resistance, generates different soil types, even in small catchments. These differentiations contribute to the development of erosion features and generate gullies covering large areas and whose evolution is difficult to explain. Thus, the study of erosion in cuesta lands is necessary and should be expanded in Brazil. The methodology used in this study has the potential to be applied to other catchments, and can thus contribut to the study of erosion processes in cuestas.

A erosão do solo pela água é estimada em um custo anual de bilhões de dólares para o PIB global. Para estudar essa problemática, considera-se que avaliar a disposição espacial dos fenômenos erosivos, assim como a interação das variáveis que influenciam sua dinâmica, constitui-se em uma prerrogativa essencial. Neste sentido, o objetivo deste artigo é apresentar procedimentos metodológicos adotados para o desenvolvimento de cartas de síntese a fim de identificar o potencial dos terrenos ao avanço da erosão linear. As variáveis utilizadas para analisar o potencial erosivo foram a morfometria do relevo, as características físicas dos solos e o uso da terra. Foram utilizados princípios da álgebra de mapas, com destaque para a sobreposição ponderada das variáveis, partindo de influências diferentes para cada uma destas e de técnicas distintas para o estabelecimento de pesos para as classes de cada variável. Os documentos cartográficos criados foram avaliados a partir da comparação destes com dados experimentais de campo e de mapeamentos das feições lineares. Constatou-se que as melhores respostas ocorreram quando se considerou influência equânime para as variáveis físicas e de uso da terra, demonstrando que as feições erosivas são fruto da interação entre a ação humana e as características naturais do terreno. Foi possível também concluir que os procedimentos técnicos que permitem obter bons resultados para avaliar o potencial ao desenvolvimento de voçorocas, não respondem adequadamente para sulcos e ravinas, havendo necessidade de adaptações. Considera-se que as cartas elaboradas, assim como os procedimentos metodológicos desenvolvidos, possuem sustentação para a análise da dinâmica erosiva linear em setores de Cuesta, uma vez que foi possível obter produtos cartográficos que apresentaram boa correspondência espacial com as feições erosivas registradas no terreno.

No Estado de São Paulo, após o longo período de estiagem nos anos de 2014 a 2015, a problemática acerca das crises hídricas passou a ser foco de diversos estudo. Alguns destes estudos propõem o uso de águas subterrâneas para evitar crises hídricas, todavia muitos destes não compreendem ou ignoram os processos hidrológicos de recarga e descarga dos aquíferos. Há uma grande defasagem cientifica acerca dos processos hidrológicos dos aquíferos, e esse déficit dificulta o planejamento de uso sustentável dos reservatórios. Entender os processos de recarga e descarga é fundamental para prevenir problemas relacionados a aquíferos e compreender melhor as relações de trocas entre os reservatórios superficiais e subterrâneos. Estudos geofísicos são usados para estudar esses processos hidrológicos, entretanto existe pouca bibliografia acerca do uso do método da Eletrorrestividade neste tipo de estudo. O presente trabalho delimitou uma área próxima da escarpa do front da Cuesta Basáltica no município de Ipeúna (SP), para estudar os processos de recarga e descarga por meio do método da Eletrorrestividade e de um levantamento estratigráfico. A área escolhida está em uma área de afloramento do Sistema Aquífero Guarani (SAG), local conhecido por ser importante na recarga desse aquífero transfronteiriço. O levantamento estratigráfico foi feito por meio de um caminhamento pela estrada de acesso à área de estudo. No levantamento geofísico foi necessário realizar 10 linhas pararelas de tomografia elétrica em arranjo Schlumberger. Os valores de resistividade medidos variaram entre 5000 Ω.m e 20 Ω.m. Os dados coletados em campos foram processados e representados em modelos logarítmicos bidimensionais e tridimensionais. Com a correlação entre a estratigrafia e os modelos 2D foi possível localizar onde estavam localizados os aquíferos porosos e fraturados, assim como relacionar os valores de resistividade com as rochas presentes na área, que são: Basaltos, Arenitos e Arenitos silicificados. O aquífero poroso funciona como um grande reservatório, a água é armazenada nele antes de fluir para o aquífero fraturado abaixo. O 3D permitiu uma melhor visualização da presença de água no arcabouço geológico, e a visualização dos valores de resistividade nas cotas. O modelo de bloco 3D possibilitou visualizar a água dentro de uma grande lente arenítica que flui em direção ao front da Cuesta, e não para o reverso como era esperado. A análise conjunta entre a geofísica e estratigrafia permitiu compreender sobre o arcabouço geológico, a relação do mesmo com o fluxo de água subterrânea e os processos hidrológicos. O trabalho também diminui a lacuna de estudos geofísicos no SAG e de uso de Eletrorrestividade para compreender os processos hidrológicos dos aquíferos. The problem of the water crisis is a concern even in countries with large amounts of fresh water, such as Brazil. In the State of São Paulo, after the long period of drought in the years 2014 to 2015, the issue of water crises became the focus of several studies. Some of these studies propose the use of groundwater to avoid water crises, however many of them do not understand or ignore the hydrological processes of aquifer recharge and discharge. There is a large scientific gap regarding the hydrological processes of aquifers, and this deficit makes it difficult to plan the sustainable use of reservoirs. Understanding the recharge and discharge processes is essential to prevent problems related to aquifers and to better understand the exchange relationships between surface and underground reservoirs. Geophysical studies are used to study these hydrological processes, however there is little bibliography about the use of the Electrorestivity method in this type of study. The present work delimited an area close to the escarpment of the Cuesta Basáltica front in the municipality of Ipeúna (SP), in order to study the recharge and discharge processes using the Electrorestivity method and a stratigraphic survey. The chosen area is in an upwelling area of the Guarani Aquifer System (SAG), a place known to be important in the recharge of this transboundary aquifer. The stratigraphic survey was carried out by walking along the access road to the study area. In the geophysical survey, it was necessary to carry out 10 parallel lines of electrical tomography in Schlumberger arrangement. The measured resistivity values ranged between 5000 Ω.m and 20 Ω.m. Data collected in fields were processed and represented in two-dimensional and threedimensional logarithmic models. With the correlation between stratigraphy and 2D models, it was possible to locate where the porous and fractured aquifers were located, as well as to relate the resistivity values with the rocks present in the area, which are: Basalts, Sandstones and Silicified Sandstones. The porous aquifer acts as a large reservoir, water is stored in it before flowing into the fractured aquifer below. The 3D allowed a better visualization of the presence of water in the geological framework, and the visualization of resistivity values in the dimensions. The 3D block model made it possible to visualize the water inside a large sandstone lens that flows towards the front of the Cuesta, and not to the reverse as expected. The joint analysis between geophysics and stratigraphy allowed us to understand the geological framework, its relationship with groundwater flow and hydrological processes. The work also reduces the gap in geophysical studies in the SAG and the use of Electrorestivity to understand the hydrological processes of aquifers.

Au cœur du relief de côtes de la Lorraine sédimentaire, Verdun bénéficiait de solides défenses naturelles qui la protégeaient des attaques depuis l’est et le nord. À l’est, elle était protégée par la dépression marécageuse de la Woëvre, impropre aux manœuvres militaires, et par le front de la côte de Meuse. Au nord, la voie était barrée par des côtes et ravins SW-NW, découpant le plateau des Hauts de Meuse. La vallée de la Meuse, surimposée au relief avec ses méandres encaissés et son lit marécageux, a fait obstacle à la coordination des attaques allemandes sur les deux rives. L’impact de la bataille de Verdun sur le paysage se traduit moins par ce qu’on voit que parce qu’on ne voit plus. L’alternance d’attaques et de contre-attaques n’a pas permis l’installation d’ouvrages de terrain pérennes et la conservation des tranchées, et le reboisement de l’après-guerre a fait oublier qu’à la place de la forêt actuelle, il y avait un terroir agricole et forestier de type openfield, qui a perdu près de 100 000 ha de terres labourable devenues incultivables. Les traces de la guerre se voient aussi dans la reconstruction des villages et des fermes entreprise dans les années 20. Enfin, la « bombturbation » et l’apparition de nouvelles espèces dans les espaces laissés à la nature témoignent également de l’impact de la bataille. In the heart of the cuesta landscape of the sedimentary Lorraine, Verdun benefited from strong natural defences that protected the place from attacks from the east and the north. On the east side, it was protected by the marshy depression of the Woëvre, which was unsuitable for the movements of troops, and by the east-facing escarpment of the Meuse cuesta. On the north side, SW-NW ridges and ravines dissecting the plateau of the Hauts de Meuse were obstacles on the way of the German forces. The valley of the Meuse, overimposed on the plateau with its steep meanders and marshy bed, separated the two wings of the attacking armiesand prevented their efficient co-operation.The impact of the battle on the landscape is less reflected in what can be seen than in what cannot be seen any longer. Continuous attacks and counter-attacks did not allow the building of perennial defences and the conservation of trenches, and post-war reforestation made forget that where there is now a forest, there was an open-field system, which lost nearly 100,000 ha of arable land that had become uncultivable. The traces of war can also be seen in the reconstruction of villages and farms undertaken in the 1920s. Finally, the “bombturbation” and the emergence of new species in the spaces left to nature are also evidence of the impact of the battle.

Flash floods and debris flows are iconic hazards inmountainous regions with steep relief, high rainfall intensities, rapid snowmelt events, and abundant sediments. The cuesta landscapes of southern Germany hardly come to mind when dealing with such hazards. A series of heavy rainstorms dumping up to 140mm in 2 h caused destructive flash floods and debris flows in May 2016. The most severe damage occurred in the Braunsbach municipality, which was partly buried by 42,000 m(3) of boulders, gravel, mud, and anthropogenic debris from the small catchment of Orlacher Bach (similar to 6 km(2)). We analysed this event by combining rainfall patterns, geological conditions, and geomorphic impacts to estimate an average sediment yield of 14,000 t/km(2) that mostly (similar to 95%) came from some 50 riparian landslides and channel-bed incision of similar to 2 m. This specific sediment yield ranks among the top 20% globally, while the intensity-duration curve of the rainstormis similarly in the upper percentile range of storms that had triggered landslides. Compared to similar-sized catchments in the greater region hit by the rainstorms, we find that the Orlacher Bach is above the 95th percentile in terms of steepness, storm-rainfall intensity, and topographic curvatures. The flash flood transported a sediment volume equal to as much as 20-40% of the Pleistocene sediment volume stored in the Orlacher Bach fan, andmay have had several predecessors in the Holocene. River control structures from 1903 and records of a debris flow in the 1920s in a nearby catchment indicate that the local inhabitants may have been aware of the debris-flow hazards earlier. Such recurring and destructive events elude flood-hazard appraisals in humid landscapes of gentle relief, and broaden mechanistic views of how landslides and debris flows contribute to shaping small and deeply cut tributaries in the southern Germany cuesta landscape.

Iași Municipality as other urban areas around the world has a long history of landslide activity which needs to be studied considering the urban sprawl. We performed a first landslide susceptibility modeling for Iași Municipality based on the AHP method using weights given by expert judgements regarding the influence of preparatory and conditional landslides factors (slope, ruggedness, lithology, historic landslide density and hydrogeology) and weights given by the historic landslide density over the factors. The landslide inventory was performed based on LiDAR data and aerial imagery using the geomorphological mapping of landslide elements. Using the landslide probability density function we have shown that the landslide inventory is valid and we have selected 411 landslides considered recent to be used for the validation. The resulted susceptibility show that the most susceptible to landslide reactivations are the hillslopes of cuesta hills with relict and old landslides, especially at the main scarp. Recent landslides are mainly scarp slumps or landslide body translational reactivations. The validation showed that almost 70% of recent landslides are located on high susceptibility areas. Future work to improve the susceptibility and extend it to hazard modeling is needed considering the long history of landslide reactivations from Iași Municipality and the slow evolution of old landslides like in Țicău neighborhoods.

This article analyzes the social and cultural context of Juan Ramon Jimenez through his relationship with Leon Sanchez Cuesta, also known as “the librarian of the generation of 27”. For this purpose we review different bibliographic sources, including the unpublished correspondence between Sanchez Cuesta and Juan Ramon Jimenez. Two of these letters are included in this article. Sanchez Cuesta was a friend and sole distributor of the works of Juan Ramon Jimenez during (approximately) the years 1925-1933. He played an important role spreading the work of Juan Ramon and providing him with reading materials. Sanchez Cuesta also played an important mediator role in some disputes between Juan Ramon and some poets of the “generation of ‘27”. Sanchez Cuesta is a key figure in the life of Juan Ramon Jimenez and his correspondence increases our understanding of both the social and cultural context and the reading habits of Juan Ramon Jimenez.

[SPA] Napoli fai-da te es una ciudad espontánea, construida al margen de las reglas del urbanismo, a veces autoconstruida; una ciudad que forma una parte importante de la conurbación metropolitana. En esta espontaneidad podemos ver una tensión libertaria, contra la planificación desde arriba, la segregación funcional y social, la gestión especulativa del terreno; fenómenos que han marcado las prácticas de planificación urbana en Italia durante décadas. Por otro lado, la edificación no autorizada ha producido barrios ineficientes e inseguros que repercuten en el medio ambiente y el paisaje, con graves consecuencias sobre la calidad de vida y simulacros de desarrollo de regiones enteras del sur del Mediterráneo. Hoy es necesario reconsiderar estos territorios, a menudo abandonados y subutilizados, con una perspectiva de sostenibilidad e inclusión.

Electron spin resonance (ESR) dating of optically bleached quartz grains was performed on three sediment samples collected from the Middle Palaeolithic site of Cuesta de la Bajada (Spain). A standard multiple grain and multiple aliquot additive dose procedure was employed, and both the Al and Ti centres were measured as part of the multiple centres approach. ESR age estimates obtained for the three samples indicate that the Al centre provides a maximum possible chronology, as the Ti centres show that the Al signal was likely not systematically reset to its residual level during sediment transport. A direct comparison between ESR ages based on the Ti centres and single grain optically stimulated luminescence (OSL) ages from samples collected nearby shows broadly consistent results. The Ti-H centre also appears to provide suitable chronologies for at least two of the three Middle Pleistocene samples studied here. Surprisingly, the only sample showing consistent ESR ages between the Al and Ti centres appears to be overestimated in comparison with the Ti-centre and OSL ages derived from the other two samples. This indicates either incomplete bleaching of both the Al and Ti centres for this sample, or unexpected impacts of other sources of De uncertainty, such as multi-grain averaging effects. The ESR dating results overall indicate that the archaeological sequence of Cuesta de la Bajada CB-3 is most likely correlated to either MIS 7 or 9.

Seismic reflection data and field observations have revealed the presence of voluminous igneous sill complexes emplaced into organic-rich shale formations in sedimentary basins worldwide. Damage and structures associated with sills have major implications for fluid flow through basins. Constraining the distribution of these structures requires a good understanding of the sill emplacement mechanism. However, most mechanical models of sill emplacement assume elastic host behaviour, whereas shale is expected to deform inelastically. This contradiction calls for new field observations to better constrain sill emplacement mechanisms. In this paper, we report on detailed field observations of spectacularly exposed fingers and a sill emplaced in shale at Cuesta del Chihuido, in the Neuquén Basin, Argentina. Exceptional outcrop conditions allow detailed descriptions of both (1) the entire cross-section of the intrusions, and (2) the deformation structures accommodating intrusion propagation in the host rock. All intrusions exhibit irregular, blunt or rectangular tips. The structures accommodating the tip propagation are systematically compressional, including reverse faults, folding and imbricate thrust system. Our observations suggest that the studied intrusions have propagated by pushing the host rock ahead, as a viscous indenter. Our observations suggest that the viscous indenter model is probably a dominant mechanism of sill emplacement in shale., Facultad de Ciencias Naturales y Museo

Along its contact with the Baltic Shield, the margin of the East European Platform reveals a well-developed, flooded terraced relief. The most striking and consistent set of escarpments at the contact of the Lower Palaeozoic calcareous and terrigenous rocks, known as the Baltic Klint (BK), extends from northwest of Russia to the Swedish island of Oland. Marine seismic reflection profiling in 1990–2004 revealed the central Baltic Sea Klint (BSK) section in detail and enabled comparison of its geology/geomorphology with a classical klint-section onshore, namely the North Estonian Klint (NEK). The conception of the BK onshore, which is based on the land-sea separating terraced relief in northern Estonia, is not fully applicable beneath the sea. Therefore, we consider that the BSK includes the entire terraced Cambrian outcrop. We suggest the term “Baltic Klint Complex” to include the well-terraced margin of the Ordovician limestone outcrop, which is weakly developed in Estonia. Because of a steady lithological framework of the bedrock layers across the southern slope of the Fennoscandian Shield, the central BSK in the western and the NEK in the eastern part of the Baltic Homocline have largely identical morphologies. The North Estonian Ordovician limestone plateau with the calcareous crest of the BK extends across the central Baltic Sea, whereas morphological changes/variations along the Klint base occur due to the east-westerly lithostratigraphic/thickness changes in the siliciclastic Cambrian sequence. The verge of the NEK, located some 30–50 m above sea level, starts to drop in altitude as its east-westerly course turns to northeast-southwest in western Estonia. Further westwards, the BK shifts gradually into southerly deepening (0.1–0.2°) layers as its crest drops to c. 150 m below sea level (b.s.l.) near Gotska Sandon. This course change is accompanied by a considerable decrease in thickness of the platform sedimentary cover, as below the central Baltic Sea the stratal sequence is 150–250 m thinner than in northern Estonia. This has facilitated a deviation of the terraced relief-forming Cenozoic rivers traversing east-westerly across the southern slope of the Fennoscandian Shield and forming different morphostructures in its eastern and western parts. Thus, a low-lying central Baltic Sea depression with well-developed asymmetrical cuesta valleys and terraces occur in the western half of the Baltic Homocline. In its eastern part, however, the only explicitly shaped cuesta valley along the shield-platform boundary forms a narrow east-westerly branch/gulf of the Baltic Sea (Gulf of Finland). The well-terraced southern margin of this gulf runs along the contact of the outcropping terrigenous and calcareous rocks, rises above the sea and forms a complex landform known as the NEK.

[EN]: The Cuesta del Rey mammal sites located on the NE border of the Duero Basin are of great importance with regard to understand the general biostratigraphy of the basin, because Miocene mammal sites are extremely scarce in this area in comparison with the central part of the basin. The mammals identified in Cuesta del Rey-1 are: Eulipotyphla: cf. Miosorex sp.; Rodentia: Heteroxerus sp., Armantomys cf. tricristatus, Megacricetodon ibericus, Megacricetodon minor-Megacricetodon debruijni, Hispanomys sp. And Democricetodon sp. The Cuesta del Rey-1 rodent assemblage is characteristic of the end of the upper Aragonian (MN 7/8, end of the middle Miocene), equivalent to the local subzone G3 of the G zone. The presence of the genera Heteroxerus and Armantomys, and the predominance of Megacricetodon (with 80% of the total percentage of the minimum number of individuals of the micromammals) suggested an open savannah or steppe palaeoenvironment. The mammals identified in Cuesta del Rey-3 are: Rodentia: Megacricetodon cf. ibericus; Artiodactyla: Dorcatherium sp. and Listriodon cf. splendens. Dorcatherium sp. represents the first appearance of the Tragulidae family in the Duero Basin, suggesting the existence of permanent watercourses., [ES]: Los yacimientos con mamíferos de Cuesta del Rey, situados en el borde NE de la cuenca del Duero, tienen una gran importancia para el conocimiento general de la biostratigrafía de la cuenca debido a la extrema escasez de yacimientos miocenos con mamíferos en comparación con las partes centrales de la misma. Los mamíferos identifi cados en Cuesta del Rey-1 son: Eulipotyphla: cf. Miosorex sp.; Rodentia: Heteroxerus sp., Armantomys cf. tricristatus, Megacricetodon ibericus, Megacricetodon minor-Megacricetodon debruijni, Hispanomys sp. y Democricetodon sp. Esta asociación, principalmente por la composición de los roedores, es característica del fi nal del Aragoniense superior (fi nal del Mioceno medio), de la subzona G3 de la zona G, unidades MN 7/8. La presencia de los géneros Heteroxerus, Armantomys, y el predominio de Megacricetodon (que constituye el 80 % del porcentaje total del número mínimo de individuos de los micromamíferos), sugieren un ambiente abierto de tipo sabana o estepa. Los mamíferos identifi cados en Cuesta del Rey-3 son: Rodentia: Megacricetodon cf. ibericus; Artiodactyla: Listriodon cf. splendens and Dorcatherium sp.

The Tithonian-Valanginian time interval in the Mendoza Shelf (Neuquén Basin, Argentina) is well exposed in the Río Salado, Puesto Loncoche and Cuesta del Chihuido sedimentary sections. From those localities, more than fifty preserved oyster shells of the genus Aetostreon sp. were selected and sampled in order to perform the first δ13C curves for this particular time interval. Mineralogical and cathodoluminiscence properties, inner micromorphology of the valves, added to major and trace element geochemistry were analyzed in order to highlight the best C-O isotopic preservation. The δ13C isotope curves show values varying between 0 and-3‰ VPDB for the Tithonian-Berriasian basal section, and a positive excursion of ~2.4-2.7‰ VPDB in the Valanginian upper section. This δ13C up section trend is here considered in order to reveal eminent correlations with other sections from the Neuquén Basin, as well as the Weissert Event from the Tethys area, also on the basis of their ammonite faunal zones. The palaeotemperatures obtained from δ18O preserved values, added to a detailed sedimentological study suggest that observed δ13C anomaly may responds to a global climatic change from warm and dry to warm and humid conditions., El intervalo Titoniano-Valanginiano en la Plataforma Mendocina (Cuenca Neuquina, Argentina) se encuentra muy bien representado en las secciones sedimentarias estudiadas de Río Salado, Puesto Loncoche y Cuesta del Chihuido. En estas localidades más de cincuenta valvas de ostras del género Aetostreon sp. fueron seleccionadas y muestreadas con el objeto de obtener las primeras curvas de δ13C de este particular intervalo temporal. Las propiedades mineralógicas, la respuesta a la catodoluminiscencia, así como la micromorfología interna de las valvas, sumado al análisis geoquímico de los elementos mayoritarios y trazas fueron utilizados para indicar las zonas con el más alto grado de preservación isotópica del C y O. La curva de δ13C muestra valores que varían entre 0 y -3‰ VPDB para la sección basal de edad titoniana-berriasiana y una excursión positiva de ~2.4-2.7‰ VPDB para la sección cuspidal de edad valanginiana. Esta tendencia del δ13C hacia el tope de la sección revela una eminente correlación con otras secciones de la Cuenca Neuquina como así también con el Evento Weissert para el área del Tetis, también respaldada por la fauna de amonites presente. Las paleotemperaturas obtenidas aquí a partir de los datos de δ18O, sumado al estudio sedimentológico de detalle sugieren que la anomalía de δ13C podría ser la respuesta a un cambio climático desde condiciones cálidas y áridas a cálidas y húmedas registrado a nivel global, Centro de Investigaciones Geológicas

The presence of cuesta with escarpment plays an important role in the distribution of rainfall. Its role was studied and was put together in this work. Various parameters were studied and they include: amount of rainfall, elevation, latitude and the distance from the sea. In this research, frequency analysis was performed on the parameters and the log-pearson type III was considered the most suitable distribution method. Also, principal component analysis was used to determine that two components best estimates the variables with close correlation to be rainfall, elevation, latitude and distance from the sea as component 1 and distance to nearest neighbour and longitude as component 2. With regional coefficient of variation of 22%, the area has low variability which is an indication of high rainfall values with good consistency. Annual average rainfall of South Eastern Nigeria is at 1744 mm with bi-modal double peaks in July and September as in most parts of Southern Nigeria. High rain bearing wind speed of the area with escarpment obviously affect the rainfall pattern. From the determination of the difference in mean of rainfall, it is again obvious that areas close to Udi escarpment of the cuesta have difference in mean below or slightly above mean, hence indicating the effect on rainfall.

Located just seven kilometers away from the city of Sevilla, Bormujos appears already in 1267 as a largely agrarian population, dominated by its status as a transit way between the towns of Castilleja de la Cuesta and Almensilla. The development of this agricultural activity and relations with neighboring populations have determined the development of an oral tradition in couplets, often brief, that allowed people to measure their leisure time and their agricultural chores. Explanations of the different informants reflect on the other hand a special conception of urban space stemming from oral memory.

Cuesta de la Bajada is a Middle Pleistocene site (MIS 8-9) in which some of the earliest evidence of Middle Paleolithic stone tool tradition is documented. The small format tool assemblage, dominated by simple flakes and scrapers, is associated to abundant remains of equids and cervids, in which both percussion and cut marks are well represented. The anatomical distribution of these bone surface modifications indicate primary access to fleshed carcasses by hominins. Hunting is further supported by the analysis of age profiles, in which prime adults are predominant both in equids and cervids. The taphonomic analysis of the site adds more information to human predatory behaviors as documented in other Middle Pleistocene sites and is one of the best examples of hunting documented in the Middle Pleistocene European archaeological record.

Atraves dos resultados conclui-se que a frente da cuesta, com 42% de declividade, apresenta um relevo escarpado, e o coeficiente de rugosidade indicam terras propicias para reflorestamentos, onde o manejo e conservacao do solo devem ser especificos em cada parte da microbacia. Os altos indices de circularidade e compacidade, aliados a alta declividade tem relacao com a maior velocidade da agua, resultando em erosao e alteracoes na recarga da agua subterrânea. Portanto, a recomposicao florestal e fundamental nas areas de preservacao permanente, dada sua importância na regulacao do sistema hidrologico e recarga do aquifero.

MORPHOLOGICAL CHARACTERIZATION OF THE SAO PEDRO RIVER WATERSHED IN THE CUESTA OF BOTUCATU – SAO PAULO- BRAZIL 2 ABSTRACT The cuesta of Botucatu has a dissymmetric relief consisted of three parts: the cuesta reverse is 920 m altitude, followed by a steep slope, an abrupt cut, sharp in front of the cuesta, followed by a peripheral depression, the lowest altimetric position in the relief. The objectives of this study were to characterize morphologically the Sao Pedro river micro watershed and infer erosion events and recharge of the aquifer. The morphometric parameters were obtained in the planialtimetric chart (IBGE), 1:50,000 scale, Botucatu sheet SF-22-R-IV-3, georeferenced by the ArcGIS 9.2 software. The results showed that the cuesta front, 42% slope, has a steep relief, and the roughness coefficient reveals favorable land for reforest, in which soil management and conservation have to be specific to each region in the micro watershed. The high indices of roundness and compactness coupled with the high slope are related with the higher speed of water, which causes erosion and changes in the recharge of ground water. Therefore, forest recovery is vital in areas of permanent preservation, considering its importance in the regulation of the hydrological system and aquifer recharge.

Characteristic landscapes (e.g., cuesta, cliff and overhang of caprock, or stepped terrain) formed by differential erosion can be found in areas composed of variable geology exhibiting different resistances to weathering. Parallel retreat of slopes, defined as recession of slopes without changes in their topography, is sometimes observed on slopes composed of multiple strata. However, the conditions needed for such parallel retreat have not yet been sufficiently clarified. In this study, we elucidated the conditions for parallel retreat of rock slopes composed of alternating layers using a geometric method. In addition, to evaluate whether various rock slopes fulfilled the conditions for parallel retreat, we analyzed topographic data obtained from periodic measurement of rock slopes in the Aka-kuzure landslide, central Japan. Our geometric analysis of the two-dimensional slopes indicates that dip angle, slope gradient, and erosion rate are the factors that determine parallel retreat conditions. However, dip angle does not significantly affect parallel retreat conditions in the case of steep back slopes (slope gradient > 40°). In contrast, dip angle is an important factor when we consider the parallel retreat conditions in dip slopes and gentler back slopes (slope gradient

The sacral complex of the Valle dei Templi in Agrigento, added in the UNESCO Heritage Site List, stands over the crest of a rigid calcarenite cuesta, which overlies a layer of partially saturated (S = 6–12%) carbonate sand. In turn, the sand stratum lies on a thick stratum of clays. The environment is highly prone to landslides as highlighted by several previous studies that identify the undermining of slopes and the discontinuity pattern, occurred in the late Neotectonic phase, as causes of cliff failure. For wider and less exposed areas, where the undermining local instabilities can be present because of the specific morphology of the site, a recent research has proposed a new interpretation of the failure general mechanism. The new hypothesis here proposed would ascribe to the collapsible behaviour of the sand; both the failure mechanisms of the cliffs and the development of the discontinuities in the rock mass. A unitary framework is then proposed. A series of direct shear and oedometer tests was performed on the collapsible sand samples and values of collapse potential were estimated. As typical for collapsible soils when flooded, vertical strains occurred rapidly causing an increase of shear stresses in the upper calcarenite, characterised by low values of yielding and low values of tensile strength. As a consequence, additional discontinuities occur, volumes of rock fall and cliffs move back. Both by means of in situ surveys and the analyses of involved rock deformability and strength characteristics, a soil model was considered and a modelling process developed. The model results were compared with measurements of displacements as well as dimensions of fallen blocks and consequently the comprehension of the effect of sand collapse was then possible. The identification of the new mechanism key factors allows the definition of the soil parameters that need to be monitored. In order to prevent the cliff recession for the archaeological site, the work proposes a plan of monitoring methods. These methods will be able to estimate the cliff recession, to localize “sensitive areas” and to quantify the parameters that could activate the instabilities.

El presente artículo presenta los cambios que se han producido en el discurso de los documentales de naturaleza televisivos producidos en España. Para ello, desarrolla el estudio comparativo de una muestra seleccionada de programas correspondientes a las series El Hombre y la Tierra (TVE, 1974) de Félix Rodríguez de la Fuente, y de Frank de la Jungla y La selva en casa (Molinos de Papel, 2010-2011) de Frank Cuesta. El análisis de los resultados permite señalar las transformaciones del género documental desde una paleotelevisión de servicio público, hasta las formas más recientes de neotelevisión privada y comercial.

A method to prepare hybrid geomorphological maps of the cuesta landscape in Luxembourg is presented. A hybrid geomorphological map is a combination of a classical geomorphological map and digital geomorphological information layers. The classical maps are hand drawn, utilize symbol-based legends and are printed as paper maps on a 1:10.000 scale. Digital information layers carry geospatial information that is stored in a geodatabase which is managed in a Geographic Information System (GIS). The digital geomorphological information layers include attributes that describe additional information on genesis of landforms, materials composition, process type and process activity, or other conditions. The geomorphological geodatabase serves as a repository for environmental information, which can flexibly be consulted by the end-user, e.g., for planning, land management, hazard assessment, or geoconservation purposes. Two types of geomorphological maps are presented. The first is an overview map on the landscape scale which comprises main units belonging to the cuesta (cuesta plateau and cuesta front), and to the fluvial, mass movement, periglacial, organic, aeolian and the anthropogenic environment. The second type are hybrid geomorphological maps, which here are used to show three detailed characteristic landscapes. These concern a former meander of the Sure near Bettendorf, the transition from the cuesta front to the fluvial landscape near Reisdorf, and a mass movement area along the cuesta front near Wallendorf.

The present study has been conducted in one of the five natural vegetation fragments at the Experimental Farm Edgardia, in Botucatu, S&#227o Paulo State, Brazil. In the past the forest fragment suffered disturbances due to the selective exploitation of tree species and the use of part of the surface as pasture. The objectives of this research were to evaluate the structure and the dynamics of natural vegetation. Three phytosociological surveys (2006, 2010 and 2014) were carried out in a sampled area of one hectare. The most abundant species were mapped in 2014, in a sampling unit with two hectares. Individuals of 37 families and 110 species have been recorded. The oscillation of the basal area observed through the forest inventories was due to the instability caused by disturbances. Only two out of the seven most abundant species mapped showed exponential diameter distribution. The unimodal distributions shown by the other five species have suggested that the vegetation has been occupying the most open spaces through regeneration in cycles. There was direct association between the spatial distribution and the dispersion syndrome for five out of the seven most abundant species. Three species have zoochoric dispersion, showing that wild animals populations have accomplished their function in the dispersion of seeds/fruit. The spatial distributions of four out of the seven most abundant species have provided evidence of how the regeneration of natural vegetation is being processed in this area.

O presente trabalho resulta de uma investigacao sobre a influencia da tectonica na estruturacao do relevo em um conjunto de morros testemunhos em area de cuesta, entre as provincias geomorfologicas da Depressao Periferica Paulista e o Planalto Ocidental (regiao das Cuestas Basalticas). Tradicionalmente tem ocorrido divergencias teoricas nas investigacoes sobre a evolucao da area, em que uma perspectiva genetica erosiva contrapoe-se a uma perspectiva tectonica. Estas divergencias justificam a realizacao deste trabalho que, atraves do recorte espacial da Serra da Atalaia buscou, a partir da analise morfoestrutural, contribuir para a compreensao das implicacoes tectonicas cenozoicas na genese e evolucao do relevo de cuestas. A Serra da Atalaia constitui-se em um extenso testemunho do recuo da chamada cuesta interior, integrado ao interfluvio correspondente ao divisor de aguas dos rios Tiete e Moji-Guacu, entre os municipios de Analândia e Corumbatai (estado de Sao Paulo). Tal estudo foi realizado por meio do mapeamento da densidade de drenagem, profundidade da drenagem, clinografia e de lineamentos tectonicos que corroboraram com as proposicoes dos autores defensores dos elementos tectonicos, sem deixar de considerar a importância dos processos de erosao diferencial e de circundesnudacao atuantes na area. A B S T R A C T This work is the result of an investigation of the influence of tectonics in the relief structure in a sector of Parana Basin, limit between the geomorphologic provinces of “Depressao Periferica Paulista” and “Planalto Ocidental” (“Cuestas Basalticas”) region. Traditionally there have been differences in theoretical investigations on the evolution of the area, in which a genetic erosive perspective has opposed to a tectonic perspective. These differences justify the carrying out of this work, which, through the spatial area of Serra da Atalaia sought, from the morphostructural analysis, contribute to the understanding of cenozoic tectonic implications in the genesis and evolution of the “Cuestas Basalticas” region. The Serra da Atalaia is an extensive testimony of the retreat of the so called intern cuesta, integrated to the interflow corresponding to the water divisor of the rivers Tiete and Moji-Guacu, between the cities of Analandia and Corumbatai (state of Sao Paulo). This study was carried out by the mapping of the drainage density, drainage deep, declivity and tectonic lineaments which corroborated with the authors who defends the tectonic elements, without failing to consider the importance of the differential erosion and “circundesnudacao” processes actives in the area. Key-words: Structural Geomorphology, Morphoestructural analysis; lineaments.
