Pre-Carboniferous Evolution of the San Rafael Block, Argentina. Implications in the SW Gondwana Margin: An Introduction
(Springer, 2017)
The San Rafael Block as part of the Cuyania terrane, lies eastwards of the present-day Andean Cordillera in Mendoza province and it develops south of the Nazca flat-slab subduction zone. It is a geographical region constituted ...
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 ...
P-T-t evolution of an Early Silurian medium-grade shear zone on the west side of the Famatinian magmatic arc, Argentina: Implications for the assembly of the Western Gondwana margin
(ELSEVIER, 2008-03)
The geodynamic evolution of the proto-Andean margin of Gondwana during the Paleozoic was characterized by repeated subduction processes associated with the docking of several terranes, including the Cuyania-Precordillera ...
Pre-Carboniferous Tectonic Evolution of the San Rafael Block, Mendoza Province
(Springer, 2017)
The pre-Carboniferous evolution of the San Rafael Block is described in different stages. The first one is referred to the Mesoproterozoic basement derived from a complex plutonic and volcanic protolith of Cerro La Ventana ...
Late Cambrian-Early Ordovician magmatism in the Sierra de Pie de Palo, Sierras Pampeanas (Argentina): Implications for the early evolution of the proto-Andean margin of Gondwana
(Cambridge University Press, 2020-02-18)
The Sierra de Pie de Palo, in the Argentinean Sierras Pampeanas (Andean foreland), consists of a Mesoproterozoic basement and an Ediacaran-upper Cambrian sedimentary cover that underwent folding, thrusting and metamorphism ...
Ordovician metamorphic event in the carbonate platform of the Argentine Precordillera: Implications for the geotectonic evolution of the proto-Andean margin of Gondwana
(Geological Society of America, 2009-12)
An Ordovician metamorphic event is recorded by means of conodont paleothermometry in the slope sedimentary sequences of the Western Precordillera. Allochthonous conodonts from reworked deposits of the eastern carbonate ...
