The Gondwana-South America Iapetus margin evolution as recorded by Lower Paleozoic units of western Precordillera, Argentina: The Bonilla Complex, Uspallata
(Instituto Superior de Correlación Geológica, 2013-06)
Terrane, accreted to Gondwana South America during Ordovician times. The Bonilla Complex, which represents the southern tip of the Precordillera, is constituted of metasedimentary rocks of internal and external platform ...
The age of the Tunas formation in the Sauce Grande basin-Ventana foldbelt (Argentina): Implications for the Permian evolution of the southwestern margin of Gondwana
(Elsevier, 2013-08)
New SHRIMP radiogenic isotope dating on zircons in tuffs (280.8 1.9 Ma) confirms the Early Permian (Artinskian) age of the uppermost section of the Tunas Formation. Tuff-rich levels in the Tunas Formation are exposed in ...
New time constraints for the age of metamorphism at the ancestral Pacific Gondwana margin of southern Chile (42-52°S)
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2002)
Shrimp zircon geochronology constrains on Permian pyroclastic levels, Claromecó Basin, South West margin of Gondwana, Argentina
(Pergamon-Elsevier Science Ltd, 2018-08)
Pyroclastic levels are descripted in Sierras Australes outcrops and Claromeco Basin sub-surface records, interbedded with mudrocks and coal beds in the base of the Tunas Formation sequence that correspond to the Permian ...
Pre-Carboniferous Evolution of the San Rafael Block, Argentina. Implications in the SW Gondwana Margin: An Introduction
(Springer, 2017)
The San Rafael Block as part of the Cuyania terrane, lies eastwards of the present-day Andean Cordillera in Mendoza province and it develops south of the Nazca flat-slab subduction zone. It is a geographical region constituted ...
Mississippian lamprophyre dikes in western Sierras Pampeanas, Argentina: Evidence of transtensional tectonics along the SW margin of Gondwana
(Pergamon-Elsevier Science Ltd, 2018-04)
In the Famatina range, Sierras Pampeanas of Argentina (SW Gondwana), subvertical calc-alkaline lamprophyric dike swarms crop out through >300 km. The dikes cut Ordovician units with a prominent NW-SE trending and are covered ...
Assembly of Pampia to the SW Gondwana margin: A case of strike-slip docking?
(Elsevier Science, 2012-03)
Different hypotheses have been proposed to account for the geologic evolution of the southwestern margin of Gondwana in the Early Paleozoic, involving accretion and displacement of different terranes in a protracted ...
Contemporaneous assembly of Western Gondwana and final Rodinia break-up: Implications for the supercontinent cycle
(Elsevier Science, 2017-11)
Geological, geochronological and isotopic data are integrated in order to present a revised model for the Neoproterozoic evolution of Western Gondwana. Although the classical geodynamic scenario assumed for the period ...
