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 ...
Late Paleozoic deformation and exhumation in the Sierras Pampeanas (Argentina): 40Ar/39Ar-feldspar dating constraints
(Springer, 2017-09)
Systematic 40Ar/39Ar feldspar data obtained from the Sierras Pampeanas are presented, filling the gap between available high- (>~300 °C) and low-temperature (<~150 °C) thermochronological data. Results show Silurian–Devonian ...

U–Pb SHRIMP detrital zircon ages from the Neoproterozoic Difunta Correa Metasedimentary Sequence (Western Sierras Pampeanas, Argentina): Provenance and paleogeographic implications
(Elsevier Science, 2015-11)
The central and eastern parts of the Sierra de Pie de Palo (Western Sierras Pampeanas, Argentina) areformed by a Mesoproterozoic basement and a Neoproterozoic sedimentary cover. Both were involvedin an accretionary orogeny ...
Preandean geological configuration of the eastern North Patagonian Massif, Argentina
(Elsevier, 2013-01)
The Preandean geological configuration of the eastern North Patagonian Massif is established through the use of geological and geophysical analysis. The positive gravity anomalies located near the Atlantic coast are due ...
Provenance analysis of Devonian peripheral foreland basins in SW Gondwana, case of the Gualilán Group, Precordillera Argentina
(Springer, 2020-10)
We carried out a sedimentary provenance analysis of the Devonian Gualilán Group, Central Precordillera of western Argentina, focusing on the siliciclastic record of the Talacasto (Lower Devonian) and the Punta Negra ...
A cambrian mixed carbonate–siliciclastic platform in SW Gondwana: Evidence from the Western Sierras Pampeanas (Argentina) and implications for the early Paleozoic paleogeography of the proto-Andean margin
(Springer, 2018-10)
The Western Sierras Pampeanas (WSP) of Argentina record a protracted geological history from the Mesoproterozoic assembly of the Rodinia supercontinent to the early Paleozoic tectonic evolution of SW Gondwana. Two well-known ...

(Springer, 2018-05)
The Western Sierras Pampeanas (WSP) of Argentina record a protracted geological history from the Mesoproterozoic assembly of the Rodinia supercontinent to the early Paleozoic tectonic evolution of SW Gondwana. Two well-known ...
Synkinematic interplay between felsic dykes and host rock mylonitization: how magmatism assists the formation of ductile narrow shear zones in the Sierra Chica de Córdoba, Argentina
(Pergamon-Elsevier Science Ltd, 2021-03-09)
This study provides new insights about mechanisms of synkinematic interplay between dyking emplacement and ductile narrow shear zones formation in the Sierra Chica de Córdoba. A detailed analysis of structural, microstructural, ...
