The Agrio Fold and Thrust Belt (FTB), situated in the Southern Central Andes at 37–39°S, underwent two phases of contractional deformation: Late Cretaceous‐Eocene and middle‐late Miocene. Despite advances in understanding its tectonic history, many questions persist regarding the timing and activity of specific structures during these deformation p...
Shallowing-upward clastic successions are very common in ancient shelfal systems. These deposits are commonly described as “parasequences” controlled by high-frequency sea-level changes. Nevertheless, the real significance of these parasequences in terms of depositional environments is controversial. This contribution discusses the origin of shallo...
