Petrology and geochronology of the San Martín de los Andes batholith: Insights into the Devonian magmatism of the North Patagonian Andes
(Pergamon-Elsevier Science Ltd, 2021-08)
Evidence is growing that a belt of Devonian plutonism is present in the Northern Patagonian segment of the present-day Andes. This plutonism formed along the paleo-Pacific margin of the Gondwana supercontinent. New whole ...
Geochronology and facies analysis of subaqueous volcanism of lower ordovician, Famatinian arc, Argentina
(Pergamon-Elsevier Science Ltd, 2018-04)
The Chuschín formation is a sedimentary-volcanic succession of the Famatina System subduction-related arc magmatism. This formation developed along the western margin of Gondwana during the early and middle Ordovician. The ...
Constraints on the Neogene growth of the central Patagonian Andes at the latitude of the Chile triple junction (45–47°S) using U/Pb geochronology in synorogenic strata
(Elsevier Science, 2018-10)
Desertification of Central Patagonia began between ~14–12 Ma and therefore was not directly connected to the opening of the Drake Passage and initial conformation of the Antarctica ice cap in early Miocene times. Local ...
New insights on landscape and environmental evolution in the Subandean region, Southern Central Andes: Sedimentology and geochronology of Guanaco Formation in the Río Chico (Jujuy, Northwestern Argentina)
(Elsevier Science, 2021-10)
During the late Miocene, the development of topography of the eastern margin of the Puna Plateau of the Central Andes, was related to the onset of the eastward migration and foreland fragmentation. The Guanaco and Piquete ...
