The South American ancestry of the North Patagonian Massif: geochronological evidence for an autochthonous origin?
New U-Pb and 40 Ar/ 39 Ar age data from deformed and undeformed granitoids of the North Patagonian Massif establish the presence of Early Cambrian and widespread Ordovician magmatism in northernExpand

Did Patagonia collide with Gondwana in the Late Paleozoic? Some insights from a multidisciplinary study of magmatic units of the North Patagonian Massif
The origin of Patagonia and its relations with the South American crustal blocks to the north have been a matter of debate for decades. We report results from a multidisciplinary study centered onExpand

Crustal segments in the North Patagonian Massif, Patagonia: An integrated perspective based on Sm–Nd isotope systematics
Abstract New insights on the Paleozoic evolution of the continental crust in the North Patagonian Massif are presented based on the analysis of Sm–Nd systematics. New evidence is presented toExpand
