Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone
Terra Nova, Volume 38, Issue 2, Page 106-115, April 2026.ABSTRACT Two giant porphyry copper deposits in the Southern Central Andes formed during the Miocene–Pliocene transition when a bend in the subducting Juan de Fernández hotspot chain jammed in the mantle transition zone, causing mega‐scale slab‐kinking. This geometry implies mechanical resistance that caused East–West compression and eventually a thrust‐

Grenvillian massif-type anorthosites in the Sierras Pampeanas
, 2016 We report the discovery of massif-type anorthosites in the Andean basement of the Western Sierras Pampeanas of Argentina. U–Pb zircon dating (by sensitive high-resolution ion microprobe) of a cogenetic gabbronorite dyke yields ages ...

Range‐Parallel Extension of the Andes in the 2020 Mw 5.7 Humahuaca Earthquake
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.Abstract Normal‐faulting earthquakes in mountain ranges provide important constraints on the dynamics of mountain building. To date, well‐documented examples of range‐parallel extension come primarily from the Tibetan Plateau, limiting our ability to test different models for its cause.

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.

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 ...
