Upper Triassic to Middle Jurassic magmatic evolution of northern Patagonia: Insights from the tectonic and crustal evolution of the Los Menucos area, North Patagonian Massif, Argentina
(Elsevier Ltd., 2021-11)
The Upper Triassic magmatic and tectonic evolution of the central North Patagonian Massif is evaluated on the basis of the zircon U–Pb-Hf record and whole-rock geochemistry for volcanic rocks of the Los Menucos area. The ...
Upper Triassic to Middle Jurassic magmatic evolution of northern Patagonia: Learned insights from the tectonic and crustal evolution of the Los Menucos area, North Patagonian massif, Argentina
(Elsevier B.V., 2021-11)
The Upper Triassic magmatic and tectonic evolution of the central North Patagonian Massif is evaluated on the basis of the zircon U–Pb-Hf record and whole-rock geochemistry for volcanic rocks of the Los Menucos area. The ...
The mejillonia suspect terrane: late triassic fast burial and metamorphism of sediments in a magmatic arc environment extending into the early jurassic
(INTERNATIONAL ASSOCIATION FOR GONDWANA RESEARCH, DEPARTMENT OF GEOSCIENCE, 2014)
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 ...
A review on the tectonic evolution of the Paleozoic-Triassic basins from Patagonia: Record of protracted westward migration of the pre-Jurassic subduction zone
(Pergamon-Elsevier Science Ltd, 2019-11)
The Paleozoic-Triassic Patagonian basins, at present comprising the Andean hinterland and structural basement of active basins, document a pre-Jurassic evolution associated with accretionary processes at the paleo-Pacific ...
The Mejillonia suspect terrane (Northern Chile): Late Triassic fast burial and metamorphism of sediments in a magmatic arc environment extending into the Early Jurassic
(Elsevier Science, 2014-04)
The Mejillonia terrane, named after the Mejillones Peninsula (northern Chile), has been traditionally considered an early Paleozoic block of metamorphic and igneous rocks displaced along the northern Andean margin in the ...
On the onset of Central Atlantic Magmatic Province (CAMP) volcanism and environmental and carbon-cycle change at the Triassic–Jurassic transition (Neuquén Basin, Argentina)
(Elsevier Science, 2020-09)
The Triassic–Jurassic transition is characterized by the end-Triassic mass extinction approximately synchronous with the onset of emplacement of the Central Atlantic Magmatic Province (CAMP), and associated with a major ...
