The Ischigualasto–Villa Unión and Northern Cuyo Triassic basins preserve one of the most complete continental records of Gondwana for reconstructing the geological and palaeontological evolution of the Triassic. Their sedimentary successions document the response of continental systems to extensional tectonics, climatic changes, the evolution of fluvial and volcaniclastic landscapes, and the diversification of the vertebrate and plant communities that characterised this period.
This field trip is designed to integrate the study of stratigraphy, sedimentology, palaeoenvironments, palaeontology, and basin evolution through the examination of key outcrops in both regions. Field observations will provide the basis for discussing the relationships between tectonics, sedimentation, and fossil preservation, as well as the stratigraphic correlations between the two basins and their significance for understanding the geological history of western Argentina.
In addition to the analysis of the surface record, the excursion will place particular emphasis on subsurface interpretation, a fundamental aspect of regional geology and sedimentary basin exploration. By combining outcrop observations with subsurface perspectives, the trip will offer an integrated view of Triassic evolution in western Argentina, from the processes that controlled basin formation to the development and preservation of some of the most iconic continental ecosystems of the Mesozoic.
