Tectono-metamorphic evolution of the proto-Andean margin of Gondwana: Evidence of internal high-grade metamorphism along the northern portion of the Famatinian orogen, Sierra de Aconquija, Sierras Pampeanas Orientales, Argentina
(Pergamon-Elsevier Science Ltd, 2021-10)
The present work gives a detailed analysis of the metamorphic and structural evolution of the back-arc portion of the Famatinian Orogen exposed in the southern Sierra de Aconquija (Cuesta de La Chilca segment) in the Sierras ...
The Famatinian orogen along the protomargin of Western Gondwana: Evidence for a nearly continuous Ordovician magmatic arc between Venezuela and Argentina
(Springer, 2018)
The continental protomargin of Western Gondwana in South America records an important Early-Middle Ordovician magmatic activity associated with the development of the Famatinian orogen. Almost the entire margin has evidence ...
High T/P evolution and metamorphic ages of the migmatitic basement of northern Sierras Pampeanas, Argentina: Characterization of a mid-crustal segment of the Famatinian belt
(Elsevier, 2011)
New petrologic, thermobarometric and U-Pb monazite geochronologic information allowed to resolve
the metamorphic evolution of a high temperature mid-crustal segment of an ancient subduction-related
orogen. The El Portezuelo ...
Crustal shortening, exhumation, and strain localization in a collisional orogen: the Bajo Pequeño Shear Zone, Sierra de Pie de Palo, Argentina
(American Geophysical Union, 2014-07)
The Bajo Pequeño Shear Zone (BPSZ) is a lower-crustal shear zone that records shortening and exhumation associated with the establishment of a new plate boundary, and its placement in a regional structural context suggests ...
Constraining the timing and evolution of a long-lived tectonic boundary: An example from the Early Paleozoic, Argentina
(Pergamon-Elsevier Science Ltd, 2021-04)
The Guacha Corral shear zone (GCSZ) is one of the most prominent crustal-scale shear zones in the Eastern Sierras Pampeanas of Argentina, juxtaposing two different metamorphic terranes: the eastern hanging wall, which was ...
Evolución del orógeno Famatiniano en la Sierra de San Luis: magmatismo de arco, deformación y metamorfismo de bajo a alto gradoEvolution of the Famatinian orogen in the Sierra de San Luis: arc magmatism, deformation, and low to high-grade metamorphism
(Asociación Geológica Argentina, 2003-12)
Se ha realizado una revisión integral de la información geológica para el basamento ígneo-metamórfico de la Sierra de San Luis y esto permite elaborar un modelo de evolución dividido en tres etapas: 1) Procesos pre-famatinianos: ...
Time constraints on the tectonic evolution of the Eastern Sierras Pampeanas (Central Argentina)
(Springer, 2010-09)
The application of the SHRIMP U/Pb dating technique to zircon and monazite of different rock types of the Sierras de Córdoba provides an important insight into the metamorphic history of the basement domains. Additional ...
