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

Journal 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 ...

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

Journal 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)

Geophysical Journal International
ملخص في هذه الدراسة، نقدم نتائج البحوث الباليومغناطيسية التي أجريت على الوحدات الجوراسية لحوض كانيادون أسفالتو (CAB) في باتاغونيا، التي تشكلت أثناء تفكك غندوانا. هذا الحوض هو موقع رئيسي لفهم التشوه داخل الصفيحة داخل باتاغونيا خلال العصر الجوراسي. كانت طبيعة هذا الحوض موضوع نقاش، بناءً على ديناميكيات الكتل التي تشكل مراكزه.

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

Andean 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]

Climate 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 ...
