Transient plate contraction between two simultaneous slab windows: Insights from Paleogene tectonics of the Patagonian Andes
(Pergamon-Elsevier Science Ltd, 2018-11)
Plate kinematic reconstructions show that the Farallon-Phoenix (Aluk) spreading center subducted under South America sometime between the Late Cretaceous and the Paleogene periods. Geological studies have supported a ...

Crustal structure of the high Andes in the North Pampean flat slab segment from magnetic and gravity data
(Pergamon-Elsevier Science Ltd, 2017-01)
The Main Andes at the northern Chilean-Pampean flat slab segment were formed by the inversion of late Oligocene to early Miocene extensional depocenters in Neogene times. Their structure, size and depth are loosely constrained ...
Stratigraphic architecture and paleosols as basin correlation tools of the early Paleogene infill in central–south Patagonia, Golfo San Jorge Basin, Argentinean Patagonia
(Pergamon-Elsevier Science Ltd, 2020-04)
The Paleogene infill of the eastern Golfo San Jorge Basin, Patagonia, Argentina, is composed of marine and terrestrial deposits. The latter are fluvial, pedogenically modified successions interlayered with eolian volcaniclastic ...
