Thermochronologic results from zircon fission track and (U-Th)/He data collected across the Patagonian batholith, basement and thrust belt of the southern Patagonian Andes between 51°S and 53°S resolves new spatiotemporal ...

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 ...

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 Andes at ~31°-32°S lie above the Chilean-Pampean flat slab zone (~27–33°S), where several morphostructural units developed resulting in a large orogenic width. The core of the Andes is composed of the La Ramada ...

The studied sector of the central Ribeira Fold Belt (SE Brazil) comprises metatexites, diatexites, charnockites and blastomylonites. This study integrates petrological and thermochronological data in order to constrain the ...

To obtain thermal histories from fission track length data, the rates at which track lengths are reduced must be estimated. the usual method is to use empirical equations calibrated via laboratory analogues. A major concern ...

The Precambrian crystalline basement of southeast Brazil is affected by many Phanerozoic reactivations of shear zones that developed during the end of the Neoproterozoic in the Brasiliano orogeny. These reactivations with ...

The tectonic regime associated with the Oligo-Miocene Cura-Mallín Formationand equivalents in the Main Andean Cordillera between 35° and 40° S, theVentana and Abanico formations to the south and north, respectively, is ...
