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 ...
The origin of the San Jorge Gulf Basin in the context of the Mesozoic-Cenozoic evolution of Patagonia
(Pergamon-Elsevier Science Ltd, 2020-01)
The retroarc region of central Patagonia recorded three contractional stages (Late Triassic, Late Cretaceous, and Miocene) coincident with eastward broadening of arc magmatism. Inboard arc migration may be linked to ...
Constraints on Trenchward Arc Migration and Backarc Magmatism in the North Patagonian Andes in the Context of Nazca Plate Rollback
Geochemical and geochronological data reveal that late Oligocene-early Miocene time is a break point in the evolution of Andean magmatism. The Patagonian Andes registered the onset of arc volcanism since the late Eocene ...
The Oligo-Miocene Tectonic Mode Switch: From a Brief Period of Widespread Extension to the Final Closure of the Neuquén Basin
(Springer, 2020)
Geological observations in the Neuquén Basin indicate a Late Oligocene to Early Miocene episode of extension followed by an abrupt shift towards regional compression. However, the reasons behind this brief extensional ...
