Successive reactivation of older structures under variable heat flow conditions evidenced by K-Ar fault gouge dating in Sierra de Ambato, northern Argentine broken foreland
(Pergamon-Elsevier Science Ltd, 2015-12)
The Argentine broken foreland has been the subject of continuous research to determine the uplift and exhumation history of the region. High-elevation mountains are the result of N-S reverse faults that disrupted a W-E ...
Isotopic and thermochronologic evidence of extremely cold lithosphere associated with a slab flattening in the Central Andes of Argentina
(Wiley Blackwell Publishing, Inc, 2017-02)
We present mineralogic, isotopic and thermochronologic analyses on psammopelitic andtuffaceous levels from the Bermejo and Vinchina basins ? both foreland depocentres of theCentral Andes of Argentina ? that define a ...
Dating recurrent shear zone activity and the transition from ductile to brittle deformation: white mica geochronology applied to the neoproterozoic Don Feliciano Belt in South Brazil
(Pergamon-Elsevier Science Ltd, 2020-09-22)
Argon geochronology of white mica has a good potential of recording recurrent dynamic recrystallization in shear zones in the transition from ductile to brittle deformation, as temperature ranges for mineral crystallization ...
Coupled anthropogenic anomalies of radionuclides and major elements in estuarine sediments

Source area evolution and thermal record of an Early Cretaceous back-arc basin along the northwesternmost Colombian Andes
(Pergamon-Elsevier Science Ltd, 2019-10)
Identifying the provenance signature and geodynamic setting on which sedimentary basins at convergent margins grow is challenging since they result from coupled erosional and tectonic processes, which shape the evolution ...
A história do intemperismo na Província Borborema Oriental, Nordeste do Brasil: implicações paleoclimáticas e tectônicas
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2008-07-25)
Until some years ago, weathering geochronology was primarily based on the K-Ar and 40Ar/39Ar dating of supergene minerals. Recent advances in the analysis of supergene goethite by the (U-Th)/He method expanded the number ...
Isotopic evidence for the late Brasiliano (500-550 Ma) ore-forming mineralization of the Araes gold deposit, Brazil
(BELLWETHER PUBL LTD, 2008)
The Araes gold deposit, located in eastern Mato Grosso State, central Brazil, is hosted in Neoproterozoic volcanosedimentary rocks of the Paraguay belt, which formed during collision of the Amazonian craton and the Rio Apa ...
