Palaeontology, Volume 68, Issue 4, July/August 2025.Abstract Taphonomic studies of Cenozoic mammals are scarce. We report a study of the taphonomy of the Corralito site (Middle Pleistocene to Holocene), Córdoba Province, Argentina, which documents the last population of the South American native ungulate typotherid Mesotherium cristatum. We discovered two specimens of M.

El metamorfismo de la Sierra Chica de Córdoba (Sierras Pampeanas). Argentina [PDF]
, 1995 Preliminary results on the regional metamorphism of the Sierra Chica (Sierras Pampeanas) are reported. The work is based on a detailed textural and mineral study of high-grade cordierite-garnet metapelitic migmatites of diatexitic type. Three events are recognized on the basis of garnet textural and chemical zoning: M1 probably represents an older ...

The Depositional Record, Volume 11, Issue 2, Page 739-763, April 2025.. The Bebedero tectonic depression in San Luis province, Argentina, is a closed drainage basin that has formed as a result of block‐faulting and rifting processes. The Bebedero lake exhibits notable similarities to the endorheic watersheds of the western United States, particularly those of Death Valley, the Saline Valley and, to a lesser extent, the ...

A 300 kyr record of past hydroclimate change from alluvial fans in the southern Central Andes
Earth Surface Processes and Landforms, Volume 50, Issue 1, January 2025.We dated alluvial‐fan deposits at the Sierra de Aconquija in northwestern Argentina. The alluvial fans aggraded and incised in phase with known hydroclimate changes throughout the last ~300 kyr. Abstract Alluvial fans are hypothesised to record signals of past hydroclimate changes in their depositional chronologies and slopes.

Geophysical Research Letters, Volume 51, Issue 19, 16 October 2024.Abstract The Central and South‐Central Andes form a “two‐sided” mountain belt bounded by distinct zones of convergence in the forearc and backarc flanks. Previous geodetic interseismic deformation studies found that the forearc to backarc velocity field is better explained when elastic models allow reverse aseismic slip on the Andes eastern‐flank ...
