Northward propagation of Andean genesis: Insights from Early Cretaceous synorogenic deposits in the Aysén-Río Mayo basin
(Elsevier Science, 2020-01)
Decoding the earliest orogenic stages in the Andes, the largest subduction orogen on Earth is fundamental to understanding changes in climate, drainage organization, and biodiversity in South America. Furthermore, it is ...
Cretaceous intraplate contraction in Southern Patagonia: A far-field response to changing subduction dynamics?
(American Geophysical Union, 2018-08-13)
The origin, extent, and timing of intraplate contraction in Patagonia are among the least understood geological processes of southern South America. Particularly, the intraplate Deseado fold-thrust belt (FTB), located in ...
Basin development at the eastern border of the Northern Puna and its relationship with the plateau evolution
(Pergamon-Elsevier Science Ltd, 2015-11)
Seismic and field-sedimentary evidence from the eastern border of the Northern Puna represent important constraints for depositional development in Andean sedimentary basin studies. The studied basin fill sequences ...
Soft-sediment deformation structures in gravelly fluvial deposits: A record of Cretaceous seismic activity in Patagonia?
(Pergamon-Elsevier Science Ltd, 2019-03)
Cretaceous sedimentary rocks corresponding to the Las Plumas Member of the Cerro Barcino Formation were deposited in the eastern margin of the Somuncurá - Cañadón Asfalto Basin. The analyzed succession records alluvial ...
Structural geology of the Fuegian Andes and Magallanes fold and thrust belt: Tierra del Fuego Island
(Universidad de Barcelona, 2008-12)
A synthesis of the structural geology of the Tierra del Fuego Island, which integrates a new data set derived from field surveys and literature data of the last few years, is here presented. The main geological features ...
