Quaternary glaciolacustrine deposits around a Triple Junction site: Paleolakes at the foot of the Northern Patagonian Ice field (Argentina and Chile)
(Servicio Nacional de Geología y Minería, 2020-05)
The area involved by the triple junction between the South American, Nazca and Antarctic plates activity was affected by Quaternary glaciations. Before 12,800 yrs BP an extended ice field occupied the top of the Patagonian ...
Ophiolite Emplacement and the Effects of the Subduction of the Active Chile Ridge System: Heterogeneous Paleostress Regimes Recorded in the Taitao Ophiolite (Southern Chile)
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2009)
A cold seep triggered by a hot ridge subduction
(Nature, 2021)
The Chile Triple Junction, where the hot active spreading centre of the Chile Rise system subducts
beneath the South American plate, offers a unique opportunity to understand the influence of the
anomalous thermal regime ...
First evidence of a mid-holocene earthquake-triggered megaturbidite south of the chile triple junction
(2018)
Megaturbidites have been the focus of many paleoseismic and paleoenvironmental studies because they can provide evidence for catastrophic and/or hazardous events with potentially major environmental implications. During a ...
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
(2018)
Desertification of Central Patagonia began between similar to 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. ...
Bimodal back-arc alkaline magmatism after ridge subduction: Pliocene felsic rocks from Central Patagonia (47 degrees S)
(ELSEVIER, 2008-03)
Volumetrically minor microsyenites, alkali microgranite and related trachytic dykes intrude early Pliocene OIB-like alkali basaltic and basanitic flows of the Meseta del Lago Buenos Aires in Central Patagonia (47 degrees ...
