Effective elastic thickness in the Central Andes. Correlation to orogenic deformation styles and lower crust high-gravity anomaly [PDF]

open access: yes, 2018
Global studies have assessed the importance of elastic thickness (Te) on orogenic evolution, showing that the style and nature of upper crustal shortening are influenced by the inherited lithospheric strength. Thus, pioneer works have identified that the

Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]

open access: yes, 2014
Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.

Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone

open access: yesTerra 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‐

Range‐Parallel Extension of the Andes in the 2020 Mw 5.7 Humahuaca Earthquake

open access: yesJournal 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.
