The igneous rocks of Cerro Cacheuta are considered a typical expression of the Permian-Triassic magmatism within the Andes Precordillera of Mendoza, Argentina. In particular, the southwestern margin of this hilltop is characterised by intermediate volcanic and felsic intrusives from the Choiyoi Group, one of the most extensive volcano-sedimentary suites of southern South America. The Choiyoi magmatism is widely associated with dramatic tectonic and environmental changes in the Gondwana supercontinent. Therefore, a better characterisation of the igneous facies of Cerro Cacheuta is critical to understand the evolution of Gondwana and recognise the multiple events that occurred towards the end of the Permian. This paper presents new data about the mineralogy, petrography, and geochemistry of the plutonic and volcanic units of Cerro Cacheuta, which enables authors to draw additional conclusions about the genesis and evolution of the magmatism in the region. Microscope observations indicate that the volcanic rocks are largely consistent with intermediate facies dominated by a porphyry texture with plagioclase and sanidine phenocrystals within a trachytic groundmass. Coetaneous breccias of possible hydrothermal origin and geodes with cryptocrystalline silica, limonite, and quartz are also recognised in outcrops. Geochemical analysis suggests that the lavas would likely correspond to andesites from a calc-alkaline magmatic arc. Furthermore, trace elements show enrichment in LREE/HREE, a slight negative anomaly in Eu, and concentration ratios compatible with crustal extension during the initial stages of the Choiyoi Group. Based on their chemical similarities, the monzonites of the Boca del Río Pluton would correlate with the lower section of the Choiyoi Group, of Permian age. In contrast, granites of the Cacheuta Pluton show a signature typically recognised in units from the Triassic and, therefore, would be comparable to the upper member of the Choiyoi Group.

This paper analyzes three short stories from La Música Interior de los Leones (2019), by Martín Cristal. It focuses on the conspiratorial nature of current narrative fictions from the perspective of dialectical hermeneutics. In the imaginary worlds of "Vivir A La Sombra", "Farmagedón", and "Ofrenda", the detective genre expands to question social phobias, rewrites the coordinates of terror, and extends uncertainty to scientific paradigms through the allusion to science fiction. Thus, the conspiracy is drawn from the discursive organization as a network of networks, a privileged, invisible, and conflictive totalizing form that allows the nuclei of domination to be read.

The article addresses the relationship between tourism, geography, and images, seeking to recognize how images mediate place tourist experience. To do this, the paper analyzes the official tourism promotion of Salta (Argentina) considering the main ideas about the destination created by local government. This is done by examining graphic material (booklets, books, magazines, brochures, posters, maps, etc.) edited and distributed by provincial government since 2007 to 2019. The analysis of graphic devices produced by provincial government shows that there are two main ideas about Salta as a tourist place. One of them portraits Salta as an unvisited place that is ideal for initial exploration. The other idea depicts it as a place where tourists can get access to an unaltered and rich cultural heritage. The text concludes by pointing out that official promotion strategy renews tourists' interest for the exotic, the different, and the remote, while allowing the multiplication of business options in a context where diversity is necessary to increase consumption.

Latin America has the greatest volume of fresh water per capita in the world. However, part of its population does not have regular access to safe water sources or has to make do with precarious water provision services. Although Argentina is one of the countries in the region with higher percentages of population served by drinking water networks, the latter are unequally distributed. Among the most affected sectors are those residing in informal settlements in the metropolitan area of Buenos Aires, the country's largest city. In this respect, the article poses the following questions: How do those sectors access drinking water networks? Why do they have less access than other sectors? On the basis of ethnography and other research tools, the paper argues that: 1) they access drinking water networks through alternative means that necessarily entail the co-participation of neighbors; and 2) their limited access is due, among other things, to the way they relate to the State in order to have the service extended to their neighborhoods. In view of these results, the article discusses notions regarding the private, public, and community management of the service and questions ideas such as governance and coproduction.

The article describes the different notions of border developed in the book La geografía y la historia en la identidad nacional (1981), written by geographers and historians during the last dictatorship in Argentina and published by the Association for the Promotion of Territorial and Environmental Studies (OIKOS). The book was compiled by the Catholic nationalist architect Patricio Horacio Randle. On the basis of the analysis carried out, the article shows how the notions of border presented there were strongly influenced by the political context of the dictatorship and by the border issues prevailing at that particular moment. In line with the findings of other researchers, the paper concludes that these types of books sought to contribute to the process of legitimating the dictatorial regime. [ABSTRACT FROM AUTHOR]
