Interpreting detrital modes and geochemistry of sandstones from the late paleozoic Tepuel-Genoa basin: Paleogeographic implications (Patagonia, Argentina)
(Pergamon-Elsevier Science Ltd, 2020-12)
The provenance of sandstones deposited in the late Paleozoic Tepuel-Genoa Basin is analyzed in this paper. Five sections were sampled in Esquel, Sierra de Tepuel, Sierra de Tecka, El Molle, and Río Genoa areas for petrographic ...
Isotopic studies on detrital zircons of Silurian-Devonian siliciclastic sequences from Argentinean North Patagonia and Sierra de la Ventana regions: comparative provenance
(Springer, 2011-12)
The Silurian-Devonian siliciclastic sedimentary units known as Sierra Grande Formation and the upper part of the Ventana Group crop out in the eastern area of the North Patagonian Massif and in the Ventania system, toward ...
Detrital-zircon geochronology and provenance of the Ocloyic synorogenic clastic wedge, and Ordovician accretion of the Argentine Precordillera terrane
(Geological Society of America, 2015-10)
The Precordillera terrane in northwestern Argentina is interpreted to be anexotic (Laurentian) continental fragment that was accreted to western Gondwanaduring the Ordovician. One prominent manifestation of the subductionand ...
U-Pb detrital ages on tuffaceous and sandstone levels from a Neogene foreland basin of the Central Andes of ArgentinaIdades U-Pb em zircões detríticos em níveis tufáceos e areníticos de uma bacia de antepaís neogénica nos Andes Centrais da Argentina
(Laboratório Nacional de Geologia e Energia, 2014-12)
Six tuffaceous and sandstone levels from an Andean (Mio-Pliocene) synorogenic succession were analyzed using the U-Pb LA-ICP-MS method on detrital zircons, in order to constrain maximum depositional ages and to define the ...
Detrital zircon geochronology and provenance of the Chubut Group in the northeast of Patagonia, Argentina
(Elsevier, 2015-11)
The Chubut Group constitutes the most widespread sedimentary unit in NE Patagonia, characterized by variable-energy fluvial deposits. U–Pb analysis of detrital zircons from two sections of the Chubut Group constraint the ...
Fluvial deposits of the Diamante Formation as a record of the Late Cretaceous tectonic activity in the Southern Central Andes, Mendoza, Argentina
(Servicio Nacional de Geología y Minería, 2020)
Estudios de procedencia de la Formación Toro Negro a partir de modas detríticas y edades U-Pb en circones detríticos: Implicancias para la evolución del antepaís fractura andino (La Rioja)Provenance studies of the Toro Negro Formation based on detrital modes and U-Pb detrital zircon ages: implications on the evolution of the Andean broken foreland (La Rioja)
(Academia Nacional de Ciencias Exactas, Físicas y Naturales, 2017-12)
La propuesta de este trabajo es mostrar la importancia de la integración de distintos métodos para analizar la procedencia de una unidad estratigráfica. Se toma como caso de estudio a la Formación Toro Negro (Mio-Pleistoceno ...
