La Peligrosa caldera (47° 15'S, 71° 40'W): A key event during the Jurassic ignimbrite flare-up in Southern Patagonia, Argentina
(Elsevier Science, 2014-01)
Pyroclastic and lava vent-facies, from the Late Jurassic El Quemado Complex, are described at the southern Lake Ghío, in the Cordillera Patagónica Austral. Based on the comprehensive study of lithology and structures, the ...
A revised interpretation of the Chon Aike magmatic province: Active margin origin and implications for the opening of the Weddell Sea
(2021)
Late Triassic – Jurassic igneous rocks of the Antarctic Peninsula and Patagonia provide evidence for the evolution of the margin of southwestern Gondwana. We present new geochronological (LA-ICP-MS zircon Usingle bondPb ...

Petrogenetic study of the Lonco Trapial volcanism and its comparison with the Early-Middle Jurassic magmatic units from northern Patagonia
(Pergamon-Elsevier Science Ltd, 2020-08)
One of the largest silicic igneous provinces of the world, the Chon Aike Volcanic Province, is related to an extensional regime developed in Patagonia in Early to Middle Jurassic times. This work presents new geochemical ...
Triassic to Middle Jurassic geodynamic evolution of southwestern Gondwana: From a large flat-slab to mantle plume suction in a rollback subduction setting
(Elsevier Science, 2019-07)
A novel geodynamic evolution model of the southwestern region of Gondwana from the late Triassic to the middle Jurassic period is proposed in this contribution, based on new data collected in the Patagonian region and an ...
