Tectonothermal evolution and exhumation history of the Paleozoic Proto-Andean Gondwana margin crust: The Famatinian Belt in NW Argentina
(ELSEVIER SCIENCE BV, 2011)
We studied the P-T-t evolution of a mid-crustal igneous-metamorphic segment of the Famatinian Belt in the eastern sector of the Sierra de Velasco during its exhumation to the upper crust. Thermobarometric and geochronological ...
Exhumation history of the Andean broken foreland revisited
(Geological Society of America, 2013-04)
The Andean broken foreland in west-central Argentina, located 400–800 km from the Peru-Chile Trench is associated with fl at subduction linked to collision of the oceanic Juan Fernandez Ridge. While the conditions associated ...
Tectonothermal evolution and exhumation history of the Paleozoic Proto-Andean Gondwana margin crust: the Famatinian Belt in NW Argentina
(Elsevier Science, 2011-09)
We studied the P-T-t evolution of a mid-crustal igneous-metamorphic segment of the Famatinian Belt in the eastern sector of the Sierra de Velasco during its exhumation to the upper crust. Thermobarometrical and geochronological ...
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 ...
Thermochronologic Evidence for Late Eocene Andean Mountain Building at 30°S
(American Geophysical Union, 2017-11)
The Andes between 28° and 30°S represent a transition between the Puna-Altiplano Plateau and the Frontal/Principal Cordillera fold-and-thrust belts to the south. While significant early Cenozoic deformation documented in ...
Structural and Thermochronological Constraints on the Exhumation of the Chos Malal Fold and Thrust Belt (~37° S)
(Springer, 2020)
This chapter reviews the evolution of the Chos Malal fold and thrust belt based on structural and thermochronological data. This fold and thrust belt can be divided into an inner-western zone, characterized by exposed ...
The relationships between tectonics, climate and exhumation in the Central Andes (18-36 degrees S): Evidence from low-temperature thermochronology
(Elsevier, 2020)
The Central Andes between 18 degrees S and 36 degrees S latitude strike north-south for 2000 km along the Chilean subduction margin, cross several climate zones from hyperarid to humid and exhibit mean elevations in excess ...
Fission track thermochronology of Neogene plutons in the Principal Andean Cordillera of central Chile (33-35°S): Implications for tectonic evolution and porphyry Cu-Mo mineralization
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2009)
Detrital Thermochronology Reveals Major Middle Miocene Exhumation of the Eastern Flank ofthe Andes That Predates the PampeanFlat Slab (33°–33.5°S)
(American Geophysical Union, 2020-04)
The Cordón del Plata and Cordón del Portillo (32.6°?33.8°S) are the portions of the FrontalCordillera that straddle the transition zone between the Pampean flat‐slab subduction segment to thenorth and the normal subduction ...
Evolution of the South Atlantic passive continental margin in southern Brazil derived from zircon and apatite (U-Th-Sm)/He and fission-track data
(2013-09-24)
The area between São Paulo and Porto Alegre in southeastern Brazil plays a key area to understand and quantify the evolution of the South Atlantic passive continental margin (SAPCM) in Brazil. In this contribution, we ...
