Extending the Pampean orogen in western Argentina: New evidence of Cambrian magmatism and metamorphism within the Ordovician Famatinian belt revealed by new SHRIMP U–Pb ages
(Pergamon-Elsevier Science Ltd, 2021-02-10)
New SHRIMP U–Pb zircon and monazite ages from the Sierra de Fiambalá (Sierras Pampeanas, NW Argentina) record coeval granitoid peraluminous magmatism and high-grade metamorphism at ca. 525 Ma (Lower Cambrian) that resulted ...
Time lag between metamorphism and crystallization of anatectic granites (Córdoba, Argentina)
(Universidad de Barcelona, 2020-11)
SHRIMP and LA-ICP-MS analyses carried out on zircons from the Río de los Sauces granite revealed their metamorphic and igneous nature. The metamorphic zircons yielded an age of 537±4.8 (2σ)Ma that probably predates the ...

Anatectic granites of the Sierras Pampeanas from Córdoba (Argentina): U-Pb SHRIMP and zircon trace element LA-ICP-MS study of diachronic metamorphism and crystallizationGranitos anatécticos de las Sierras Pampeanas de Córdoba (Argentina): edades U-Pb SHRIMP y estudio LAICP-MS de elementos traza en circón de metamorfismo y cristalización diacrónicos
(Sociedad Geológica de España, 2020-05-29)
En este trabajo se aportan nuevos datos de edades U-Pb SHRIMP y análisis in situ LA-ICP-MS de elementos traza de circones provenientes del granito Río de los Sauces, Córdoba, Argentina. A partir de marcadas diferencias ...
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 ...
Syn-deformational anatexis along the Santa Rosa river section, Argentina: Feedback relations between deformation, metamorphism and melt extraction
(Pergamon-Elsevier Science Ltd, 2019-07)
Mass transference from lower to upper crustal levels requires an efficient network of pathways that act as channels for draining melts from the source and transferring magmas through the crust. We report on a mid-crustal ...

Neoproterozoic backarc basin: Sensitive high-resolution ion microprobe U-Pb and Sm-Nd isotopic evidence from the Eastern Pampean Ranges, Argentina
(Geological Society of America, 2007-06)
The Eastern Pampean Ranges comprise high-grade supracrustal sequences with linear belts of mafic-ultramafic bodies representing ophiolite remnants. New U-Pb and Nd isotopic data suggest that the tectonic evolution of the ...
Detrital-zircon U-Pb geochronology of the Quebrada del Carrizo Metamorphic Complex and El Jardin Schists and spatially-related granitoids of the Sierra Castillo Batholith
(Servicio Nacional Geología Minerva, 2015)
U-Pb detrital-zircon geochronology of two discrete outcrops of mica schists of the western border of the Domeyko Cordillera in the Region of Atacama, northern Chile, indicates that the maximum age of sedimentation of their ...
