Failed tableland: geomorphological map of the Sarmiento Basin (extra-Andean Patagonia, Argentina)

open access: yesJournal of Maps
We present a 1:120,000 landslide-focused geomorphological map of the Sarmiento Basin (Chubut Province, Argentina) and the adjacent landscape. The study area covers about 8000 km2 and can be schematically described as an endorheic basin enclosed by ...

Geochemistry of Cenozoic plutonic rocks in the extra-Andean southern Patagonia as evidence for a magmatic arc migration process [PDF]

open access: yesAndean Geology, 2021
In this work, we present the results of a petrographic and geochemical study that involves seven Cenozoic plutons located in a NS trending belt in western Patagonia, south of the present Chile Triple-Junction and to the east of the present magmatic arc. Four plutons were studied in the northern end, and three in the southern part of the belt.

Climate history of the Southern Hemisphere Westerlies belt during the last glacial–interglacial transition revealed from lake water oxygen isotope reconstruction of Laguna Potrok Aike (52° S, Argentina) [PDF]

open access: yesClimate of the Past, 2014
The Southern Hemisphere Westerlies (SHW) play a crucial role in large-scale ocean circulation and global carbon cycling. Accordingly, the reconstruction of how the latitudinal position and intensity of the SHW belt changed during the last glacial ...

U–Pb geochronology of the meta-volcanic rocks from Sierra de Calcatapul: Implications for the Middle Triassic syn-rift volcanism and tectonic evolution of northern extra-Andean Patagonia

open access: yesJournal of South American Earth Sciences, 2021
Abstract This contribution deals first new ICP-MS U–Pb zircon ages that indicate Middle- and Late Triassic magmatic episode and tectonometamorphic events, respectively, for the central Patagonia region, instead of a Paleozoic history as previously estimated.

Intraplate deformation during Gondwana breakup: a study of the Jurassic units of the Cañadón Asfalto Basin (extra-Andean Patagonia, Argentina)

open access: yesGeophysical Journal International
SUMMARY In this study, we present the results of palaeomagnetic research conducted on Jurassic units of the Cañadón Asfalto Basin (CAB) in Patagonia, formed during Gondwana breakup. This basin is a key locality for understanding intraplate deformation within Patagonia during the Jurassic.

Structural framework and evolution of the Golfo San Jorge Basin: a synthesis

open access: yesLatin American Journal of Sedimentology and Basin Analysis
The Golfo San Jorge Basin evolved through a complex multiphase structural history from the Middle Jurassic to the Neogene. Its stratigraphic record captures key tectonic events in central extra-Andean Patagonia during Gondwana fragmentation and the ...
