Petrogenesis of Upper Paleozoic post-collisional peraluminous leucogranites, Sierra de Ancasti, northwest Argentina
(E SCHWEIZERBARTSCHE VERLAGS, 2011)
The Santa Rosa and Sauce Guacho plutons are two post-collisional peraluminous Late Devonian to Early Carboniferous leucogranites that intruded the banded schists of the Ancasti Formation. The leucogranites are composed of ...
Paleogeography of the upper Paleozoic basins of southern South America: An overview
(Pergamon-Elsevier Science Ltd, 2006-12)
The paleogeographic evolution of Late Paleozoic basins located in southern South America is addressed. Three major types of basins are recognized: infracratonic or intraplate, arc-related, and retroarc. Intraplate basins ...
Deformation understanding in the Upper Paleozoic of Ventana Ranges at Southwest Gondwana Boundary
(Nature, 2021-10)
At the east of the Ventana Ranges, Buenos Aires, Argentina, outcrops the Carboniferous-Permian Pillahuincó Group (Sauce Grande, Piedra Azul, Bonete and Tunas Formation). We carried out an Anisotropy of Magnetic Susceptibility ...
Bimodal character of the Late Paleozoic glaciations in Argentina and bipolarity of climatic changes
(Elsevier Science, 2010-12)
The Upper Paleozoic sedimentary rock sequences of Argentina show an outstanding record of climatic fluctuations during this interval and the complexity and rapidity of the climatic changes. There were two distinct events ...
An Approach to the Carboniferous-Early Permian Stratigraphy, Paleontology, Paleogeography And Paleoclimatology of the Calingasta-Uspallata Subbasin (Western Argentina) and Tepuel-Genoa Basin (Patagonia), Argentina: A Fieldguide
(International Comission on Stratigraphy. International Union of Geological Sciences, 2009-06)
The purpose of this contribution is to present to all Upper Paleozoic workers an adaptation of the fieldguide used in the “Second International Symposium and Field Workshop on the Carboniferous-Early Permian Stratigraphy, ...
Geological Characteristics of Unconventional Gas in Coal Measure of Upper Paleozoic Coal Measures in Ordos Basin, China
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencia, 2016-01-01)
There are enormous resources of unconventional gas in coal measures in Ordos Basin. In order to study the geological characteristics of unconventional gas in coal Measures in Ordos Basin, we analyzed and summarized the ...
Some interesting fossils from the upper Paleozoic in Chaparra area, Southwest Peru
(Palaeontological Society of JapanJP, 1979-09)
Four fusulinid species and one new coral species described in this article were found from the Upper Paleozoic at the south of Pampa Lobos, Chaparra area, Southwest Peru. Judging from the paleontological data, the present ...
Deciphering the late paleozoic–cenozoic tectonic history of the inner central andes forearc: an update from the salar de Punta Negra basin of Northern Chile
(Frontiers Media, 2022)
We integrated new and existing geological, geochronological, thermochronological, and two-dimensional (2D) seismic data from the Salar de Punta Negra Basin to define the Late Paleozoic-Cenozoic tectonic evolution of the ...
Deciphering the Late Paleozoic–Cenozoic Tectonic History of the Inner Central Andes Forearc: An Update From the Salar de Punta Negra Basin of Northern Chile
(Frontiers Media S.A., 2022-01)
We integrated new and existing geological, geochronological, thermochronological, and two-dimensional (2D) seismic data from the Salar de Punta Negra Basin to define the Late Paleozoic–Cenozoic tectonic evolution of the ...
Provenance of the Lower Paleozoic Balcarce Formation (Tandilia System, Buenos Aires Province, Argentina): Implications for paleogeographic reconstructions of SW Gondwana
(Elsevier Science, 2009-07)
Lower Paleozoic moderately sorted quartz-arenites from the Balcarce Formation deposited in eastern Argentina (Tandilia System) comprise mainly detrital material derived from old upper crustal material. The sources were ...
