Review of the geodynamic evolution of the SW margin of Gondwana preserved in the Central Andes of Argentina and Chile (28°-38° S latitude)
(Pergamon-Elsevier Science Ltd, 2017-11)
In the southwestern margin of Gondwana, preserved in the Argentinean-Chilean Andes (28-38° S latitude), three subduction events, Famatinian, Chanic and Gondwanan, took place from the Ordovician to the middle Permian. The ...
Triassic floras of Argentina: biostratigraphy, floristic events and comparison with other areas of Gondwana and Laurasia
(Taylor & Francis Ltd, 2003-09)
Study of the Triassic floristic record of several stratigraphic units of southern and west‐central Argentina has permitted recognition of five Assemblage Biozones and three Stages, defined on the basis of Assemblage Biozone ...
Western Paraná suture/shear zone and the limits of Rio Apa, Rio Tebicuary and Rio de la Plata cratons from gravity data
(Elsevier Science, 2017-04)
We present a new gravity map between 45°?70° W and 5°?40° S integrating open source terrestrial gravity data of Argentina with the South American Gravity Model 2004 (SAGM04), a 5 min-arc resolution gravity model. The Bouguer ...

Low-temperature thermochronology of the South Atlantic margin along Uruguay and its relation to tectonic events in West Gondwana
(Elsevier, 2020)
The geodynamic forces acting during Jurassic-Cretaceous South Atlantic rifting provoked intense transformations in West Gondwana, such as the reactivation of ancient basement structures, voluminous magmatism and general ...
Proveniência sedimentar do intervalo Devoniano : Carbonífero da Bacia Subandina de Tarija (Bolívia) e a relação com as Bacias do setor SW de Gondwana
(2022-08-30)
A evolução da margem sudoeste de Gondwana durante o Devoniano-Carbonífero tem sido
amplamente debatida. Alguns autores propõem o estabelecimento de uma margem passiva para
esse intervalo de tempo, baseado principalmente ...
Sr–Nd isotope data of basement rocks from the northernmost argentine Precordillera and its implications for the early Paleozoic evolution of SW Gondwana margin
(Pergamon-Elsevier Science Ltd., 2014-08)
The Precordillera terrane (Cuyania) in western Argentina is commonly accepted as an exotic fragmentderived from Laurentia in the Early Paleozoic. Evidence supporting such an interpretation is manly basedon similarities in ...
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 ...
Triassic continental oblique rifting controlled by Paleozoic structural grain: The Puesto Viejo Basin, western Argentina
(Pergamon-Elsevier Science Ltd, 2019-11)
The aim of the present study was to characterize in detail the Triassic structures of the Puesto Viejo Basin in San Rafael Block, western Argentina, and to establish the role of these previous structures in the development ...
