Depositional age and provenance in the San Luis Formation, Sierras Pampeanas, Argentina: Evidence from detrital zircon studies
(Elsevier Ltd, 2019)
The San Luis Formation is one of the lithostratigraphic units constituting the early Paleozoic crystalline basement of the Sierras de San Luis, which are part of the Sierras Pampeanas of central Argentina. The low-grade ...
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 ...

The late stages of the Pampean Orogeny, Córdoba (Argentina): Evidence of postcollisional Early Cambrian slab break-off magmatism
(Pergamon-Elsevier Science Ltd, 2015-08)
Widespread rhyolitic and mafic volcanism in the northern and southern sectors respectively of Eastern Sierras Pampeanas, central western Argentina, are associated with an important phase of extension and uplift linked to ...
Aeromagnetic Surveys as a Tool for Regional Geological Mapping: A Review of the Case Study of the Southeastern Pampean Ranges, Argentina
(ARC Publications, 2021-03)
A geological interpretation of the aeromagnetic survey of the southeastern Pampean Ranges of Argentina –referred to as “Sierras Pampeanas Orientales” in Spanish– , whose basement ages range from late Neoproterozoic to early ...
The age and tectonic setting of the Puncoviscana Formation in northwestern Argentina: An accretionary complex related to Early Cambrian closure of the Puncoviscana Ocean and accretion of the Arequipa-Antofalla block
(Pergamon-Elsevier Science Ltd, 2011-12)
TIMS and SHRIMP U-Pb zircon geochronology of selected parts of the Puncoviscana Formation suggest its deposition took place mainly during the Early Cambrian, coeval with 540-535. Ma calc-alkaline Pampean arc volcanism ...
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 ...
Untangling the Neoproterozoic-Early Paleozoic Tectonic Evolution of the Eastern Sierras Pampeanas Hidden in the Isotopical Record
(Springer, 2018)
The Sierras Pampeanas of Central Argentina are an example of a continuous and fast overlap of episodes of high- to medium- and low-grade metamorphism, deformation, anatexis, magmatism and mineralization along the belts ...
Late oligocene to quaternary tectonic evolution of the extra andean basins of the pampean plain, Argentina
(Pergamon-Elsevier Science Ltd, 2019-10)
The extra-Andean Pampean plain of central Argentina shows a complex evolution history. Three basins were identified in the subsurface (Salado, Macachín and Laboulaye) generated during the opening of the South Atlantic Ocean ...
