Abstract

In relationship with urban expansion at the level of cities located in the Sais basin, several projects have been carried out and others still in progress. Therefore, the recognition of the mechanical characteristics of soils and subsoil remains essential before any construction project, in order to avoid the shrinkage-swelling phenomenon associated with marls soil. In order to minimize the risk of instability, the present work consists of the characterization and study of the mechanical behavior of marly soils in some locations of Sais basin. In-situ tests have been performed in the field and samples submitted to other geotechnical tests in the laboratory such as the odometer compressibility and direct shear tests. The obtained results show that the studied marly soils exhibit strongly consolidated behaviors with the depth according to Menard test, and to the ratio of the pressiometric modulus (EM) and the corrected limit pressure (PL*).

Abstract

In the abandoned mine in Zaida, the pit lakes filled with water constitute significant water reserves. In these lakes, the waters are permanently in contact with ore deposit (cerussite and galena). The modelling of the interaction of waters with this mineralization shows that cerussite dissolves more rapidly than galena. This dissolution is controlled by the pH and dissolved oxygen concentration in solution. The lead concentrations recorded in these lakes come largely from the dissolution of cerussite.

Abstract

International audience; In a context of overexploitation of the karst system of the Middle Atlas Causses feeding the Saïs basin and the current climatic variations, the study of circulations and of renewal of waters of this system in the Fes-Meknes area becomes essential for the population, in order to maintain a sufficient quality of waters with a good management.By coupling hydrochemical and isotopic analysis methods (delta-D, delta O-18, Radon-222), saturation indices obtained from PHREEQC code and principal component analysis (PCA) of ten springs and three wells, a first conceptual model of groundwater flows of this karst system was obtained . These waters are mainly renewed by the rainfall of L'Hajeb Causse and secondarly by the rainfall of Guigo Causse containing several springs. Hydrochemistry and saturation indexes allowed us to highlight two types of waters: a main contribution of Liasic origin and two low contributions of Triassic origin at the southern extremities (SE, SW) of the basin. We pointed out the existence of five local recharge zones of different altitudes (900 to 1500 m asl.) including the two main mixing zones to the south (SE, SW). Radon-222 showed areas of rapid exchange (upwelling time less than two weeks) between waters of Liasic aquifer and the ones of Triassic origin with high radon activity.The use of PCA on hydrochemical data, allowed us to refine the kind of waters, their transit times and highlighted the existence of several mixing zones between the Triassic aquitard and the Liasic aquifers in more or less faulted structures for the two causses. Our results allow us to obtain a first conceptual model of groundwater circulations between the two causses and the Saïs basin.Previous campaigns of electrical resistivity tomography coupled with electromagnetic measurements (EM34) revealed lateral and vertical variations of electrical conductivity changing with the depth along the North-South axis, and a preferential drain perpendicularly to the causses (EGU 2009). We can note that groundwater flows are conditioned by two major fracture networks, NE-SW and NW-SE directions (Bentayeb & Leclerc 1977, Amraoui 2005). A karstic complex water circulation is especially developed locally at the border of the two hydrogeological units (Qarqori 2015).

Abstract

Two profiles were taken on two cultivated soils (a calcareous soil and a vertisol) irrigated by the wastewater in the Ourzirha area (NE of the Meknes city), to explain the variability of the contents of Trace Elements (TE), their principal associations, and to predict their origins in these soils. To the whole of the geochemical data, a multivariate statistical analysis was applied (PCA and HAC). The results showed that the contents raised on the profiles are of lithogenic origin mainly, with a notable contribution of the exogenic contributions on the surface. These exogenic contributions on the surface are very large for the Zn on the vertisol.

Abstract

Roman mosaics in Volubilis are opus tessellatum type. They show different deterioration features represented by the lacunae formation (lack of tesserae) and break down of mosaic pavements by fracturing. The deterioration of the tessellatum and the formation of cracks are related to the swelling of soil supporting these mosaics. Furthermore, the tessellatum is also damaged by chemical dissolution of the fine grained-mortar between (lime and quartz fine grain) and under tesserae, giving an important porosity and making the tessellatum very easy to collapse. A part from limestone tesserae, which show formation of vesicles by chemical dissolution, other ones such as marble and glass tesserae appear to be resistant to the weathering action., Volublis’deki Roma mozaikleri opus tessellatum tipindedir. Bu mozaikler, Lacunae düzeninde (tesserae eksikliği) belirtilenden farklı bir bozulma özelliği göstermekte olup mozaik döşemeleri çatlaklarla ve kırılmalarla bozu- lur. Tessellatum’un bozulması ve çatlakların düzeni mozaiği taşıyan topraktaki kabarmalarla ilişkilidir. Ayrıca, döşeme tesserae aralarında ve altında bulunan ve onlara önemli derecede gözeneklilik veren ve tessellatumun kolayca çökmesine sebep olan ince taneli harçtaki (ince taneli kireç ve kuvars) kimyasal bozulmalar nedeniyle de zarar görebilir. Kimyasal çözünmeden dolayı kabarcık oluşumu gösteren kireçtaşı tesseranın dışında, mer- mer ve cam tesseralar kötü havadan aşınmalara karşı direnç göstermektedir

Abstract

The objective of this study is to conduct a mineralogical and chemical characterization of the mortars Roman archaeological site of Volubilis to rebuild spare mortars for restoration. Samples of mortar, broken tile palate garden, and pavement mosaic Falavius Germanus. The analysis by X-ray diffraction reveals that the coarse mortar Flavius Germanus is made of quartz and calcite, with feldspar and probably, mica and dolomite in small amounts. The binder end is formed calcite and quartz. However, the broken tile mortar is formed by coarse particles, clay base mixed with a binder phase dominated by calcite. These results allowed us to reformulate spare mortars for the restoration of damaged Roman mosaics, the mortars are made up by 63.6% of lime and 36.4% of sand(with (4.19% of large grain, 71, 04% of coarse sand, 24.22%, of fine sand and 0.55% fines parts). The performance of these mortars was tested by mechanical testing. [ABSTRACT FROM AUTHOR]

Abstract

The ability of aquatic ( Juncus effusus L., Scirpus holoschoenus L., Thypha latifolia L. and Juncus sp.) and land ( Cistus ladanifer L., Erica andevalensis C.-R., Nerium oleander L., Isatis tinctoria L., Rosmarinus officinalis L., Cynodon dactylon L. and Hordeum murinum L.) plants from Portugal (Aljustrel, Lousal and São Domingos) and Morocco (Tighza and Zeida) mining areas to uptake, translocate and tolerate heavy metals (Cu, Zn and Pb) was evaluated. The soils (rhizosphere) of the first mining area are characterized by high acidity conditions (pH 2-5), whereas from the second area, by alkaline conditions (pH 7.0-8.5). Physicochemical parameters and mineralogy of the rhizosphere were determined from both areas. Chemical analysis of plants and the rhizosphere was carried out by inductively coupled plasma emission spectrometry. The sequential chemical extraction procedure was applied for rhizosphere samples collected from both mining areas. In the acid conditions, the aquatic plants show a high capacity for Zn bioaccumulation and translocation and less for Pb, reflecting the following metal mobility sequence: Zn > Cu > Pb. Kaolinite detected in the roots by infrared spectroscopy (IR) contributed to metal fixation (i.e. Cu), reducing its translocation to the aerial parts. Lead identified in the roots of land plants (e.g. E. andevalensis) was probably adsorbed by C-H functional groups identified by IR, being easily translocated to the aerial parts. It was found that aquatic plants are more efficient for phytostabilization than bioaccumulation. Lead is more bioavailable in the rhizosphere from Morocco mining areas due to scarcity of minerals with high adsorption ability, being absorbed and translocated by both aquatic and land plants.

Abstract

Triassic basalt of the Middle Atlas has been subject to metamorphic transformation then weathering. Occurrence in both metabasalt and saprolite of ubiquitous clay minerals, such as smectite and mixed layers chlorite–smectite, makes it difficult to distinguish between the two alteration facies and explains the interest of complementary sources of information. In the Bhallil weathering profile, petrographical and mineralogical analyses of primary igneous minerals and their alteration products coupled with Fe oxidation state determination in clay fractions allow to identify three alteration facies: (i) metamorphic basalt, where iron occurs mainly as the ferrous form; (ii) the lower part of saprolite, where iron is partially oxidized to its ferric form; (iii) the upper part of saprolite, where iron is completely oxidized.
