Tectonic insight based on anisotropy of magnetic susceptibility and compaction studies in the Sierras Australes thrust and fold belt (southwest Gondwana boundary, Argentina)
(American Geophysical Union, 2016-04-28)
The Sierras Australes fold and thrust belt (Buenos Aires Province, Argentina) was in the southwestern Gondwanaland margin during the Paleozoic. The Tunas Formation (Permian) is exposed along the eastern part of it and ...
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 ...
Neoarthropitys gondwanaensis gen. nov. et sp. nov. from the Middle Triassic of Gondwana: an intermediate stage in the anatomical trend of Equisetalean stems
(Elsevier Science, 2020-11)
A new petrified stem from the Middle Triassic Quebrada de los Fósiles Formation (Puesto Viejo Group, San Rafael Basin) in Mendoza Province, central-western Argentina, is described. The specimen shows affinities with fossil ...
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 ...

Trace fossils and the agronmomic revolution at the Neoproterozoic – Cambrian transition in Southwest Gondwana
(Elsevier, 2009-12)
The Ediacaran-Early Cambrian transition in the southwestern margin of Gondwana is represented in the Andean Margin of South America by the thick sequence of the Puncoviscana Basin. In southern Africa, the Nama and Vanrhynsdorp ...
Comments on “Devonian to Permian post-orogenic denudation of the Brasília Belt of West Gondwana: Insights from apatite fission track thermochronology” by Fonseca et al. (2020)
(2022-01-01)
In a recent paper published in the Journal of Geodynamics (vol. 137, June 2020, 101733), Fonseca et al. (2020) proposed a thought-provoking model aiming to elucidate the exhumation history of the Neoproterozoic Brasília ...
