Paleotethys slab pull, self-lubricated weak lithospheric zones, poloidal and toroidal plate motions, and Gondwana tectonics
(Geological Society of America, 2017-07)
The Gondwana megacontinent was composed of different domains separated by self-lubricated weak lithospheric zones, two of which could have extended into Laurasia. Displacement vectors determined through three consecutive ...
Fast sediment underplating and essentially coeval juvenile magmatism in the Ordovician margin of Gondwana, Western Sierras Pampeanas, Argentina
(Elsevier Science, 2012-09)
Metasedimentary high-pressure upper amphibolite facies gneisses (1.2 ± 0.1. GPa and 780 ± 45 °C) at Las Chacras, Sierra de Valle Fértil, are tectonically juxtaposed to the westernmost parts (outboard) of the Famatinian ...

Thermochronology of the Ventana Ranges and Claromecó Basin, Argentina: Record of Gondwana breakup and South Atlantic passive margin dynamics
(Pergamon-Elsevier Science Ltd, 2021-01)
The Ventana Ranges and the neighboring Claromecó basin display multiple extensional and compressional tectonic events throughout their Phanerozoic evolution. A passive continental margin setting during the early Paleozoic ...

Hf and Nd isotopes in Early Ordovician to Early Carboniferous granites as monitors of crustal growth in the Proto-Andean margin of Gondwana
(Elsevier Science, 2013-05)
We report the first study integrating in situ U-Pb and Hf isotope data from magmatic zircon and whole-rock Sm-Nd isotope data for granitic rocks of the Sierras Pampeanas, Argentina, in order to evaluate the Palaeozoic ...
Reconciling Patagonia with Gondwana in early Paleozoic? Paleomagnetism of the Valcheta granites, NE North Patagonian Massif
(Pergamon-Elsevier Science Ltd, 2021-03)
A paleomagnetic study was carried out in the Ordovician granitoids located in the northeastern North Patagonian Massif (NPM), close to Valcheta town (Río Negro Province, Argentina), to provide new evidence on the relation ...
