The Hesperides basin: a continental-scale upper Palaeozoic to Triassic basin in southern Gondwana
(Wiley Blackwell Publishing, Inc, 2016-10)
The late Palaeozoic to Triassic sedimentary record of the central Argentinean offshore was analysed through the integration of data from exploratory wells and 2D seismic lines. Our interpretations were combined with existing ...
Neoproterozoic to lower Palaeozoic successions of the Tandilia System in Argentina: Implication for the palaeotectonic framework of southwest Gondwana
(Springer, 2011-04)
The Cryogenian to Uppermost Ediacaran successions of the Tandilia System (Sierras Bayas Group and Cerro Negro Formation) in central-eastern Argentina is exceptional because of its unmetamorphosed and nearly undeformed ...
Palaeomagnetism of the Upper Carboniferous-Lower Permian transition from Paganzo basin, Argentina
(Wiley Blackwell Publishing, Inc, 2004-06)
A palaeomagnetic study of Upper Palaeozoic rocks was performed on Paganzo basin, central-western Argentina and its western extension, Río Blanco subbasin. The volcanic-volcaniclastic Rio del Peñón and marine sedimentary ...
The marine upper Palaeozoic in Patagonia (Tepuel-Genoa Basin, Chubut Province, Argentina): 85 Years of work and future prospects
(Elsevier Science, 2010-12)
Argentina is a special place to study Late Palaeozoic life and environmental change because of the excellent exposures of Late Palaeozoic sedimentary sequences. In particular, Patagonia has an almost continuous Late ...
Lamellorthoceratid cephalopods in the cold waters of Southwestern Gondwana: Evidences from the Lower Devonian of Argentina
(Polish Academy of Sciences. Institute of Paleobiology, 2020-05)
Based on three specimens assigned to Arthrophyllum sp., the family Lamellorthoceratidae is reported from the Lower Devonian Talacasto Formation in the Precordillera Basin, central western Argentina. These Devonian cephalopods ...
The Choiyoi volcanic province at 34°S-36°S (San Rafael, Mendoza, Argentina): Implications for the Late Palaeozoic evolution of the southwestern margin of Gondwana
(Elsevier Science, 2009-08)
The Choiyoi rhyolitic province of Chile and Argentina (23°S-42°S) was emplaced at the SW margin of Gondwana during the Permian. The San Rafael Massif (Mendoza, Argentina, 34°-36°S), is a key area to analyse the relative ...
Evolution of the Palaeozoic basement of the North Patagonian Andes in the San Martín de los Andes area (Neuquén, Argentina): petrology, age and correlationsEvolución del basamento paleozoico de los Andes Norpatagónicos en el área de San Martín de los Andes (Neuquén, Argentina): petrología, edad y correlaciones
(Servicio Nacional de Geología y Minería, 2019-01)
En el entorno de San Martín de los Andes (Patagonia argentina), el basamento Paleozoico está constituido por rocas metamórficas e ígneas. Las rocas metamórficas de esta área incluyen esquistos, gneises y migmatitas ...
