A New Tectonic Model for the Contact Relationships of Mesozoic and Cenozoic Domains in the Principal Cordillera, Central Chile (33°–34°S) Open
The origin of the contact between Cenozoic rocks of the Western Principal Cordillera (WPC) and Mesozoic rocks of the Eastern Principal Cordillera (EPC) in the Chilean Andes at 33°–34°S has been debated for several years. Most authors inter…

The Miocene lacustrine carbonate factory of the Ñirihuau Formation, Ñirihuau Basin, North Patagonian Andes, Argentina Open
Facies, microfacies and stable isotope analyses of limestone beds in the northernmost Ñirihuau Basin, North Patagonian Andes, Argentina, document and constrain the past hydrological, sedimentological and climate conditions that prevailed d…

The transition from backarc extension to Andean growth: Insights from geochronologic, sedimentologic, and structural studies of Mesozoic and Cenozoic sedimentary and volcanic rocks in south-central Chile (36°S) Open
Many studies propose a significant shift in the tectonic and paleogeographic evolution of the Andes in south-central Chile and Argentina during the Late Cretaceous. It has been proposed that the preceding Jurassic-Early Cretaceous extensio…

Oxfordian microbial laminites from La Manga Formation, Neuquén Basin, Argentina: Remarkable nanobacteria preservation Open
[EN] Exceptionally preserved stromatolites have been found in the shallow marine carbonate facies of the Callovian-Oxfordian La Manga Formation,
\nin the Neuquén Basin (Argentina). The stromatolites exhibit planar and crinkle lamination, o…
