New invertebrate peri-glacial faunal assemblages in the Agua de Lucho formation, Río Blanco basin, Argentina: the most complete marine fossil record of the early mississippian in South America
(Pergamon-Elsevier Science Ltd, 2021-03)
A new fossil record of early Mississippian marine faunas is described from the Agua de Lucho Formation in the Sierra de las Minitas (La Rioja province, Río Blanco Basin, western Argentina). Considered Tournaisian in age ...
Unraveling the origin of the Parnaíba Basin: Testing the rift to sag hypothesis using a multi-proxy provenance analysis
(2020-08-01)
Syneclises are long-lived sedimentary basins characterized by complex subsidence and erosion histories. The premise that these geotectonic units evolve from initial rifting processes following thermal (or flexural) subsidence ...
Dinos among the dunes: Dinoturbation in the Pirambóia Formation (Paraná Basin), São Paulo State and comments on cross-section tracks
(2021-08-01)
Soft-sediment deformation structures are conspicuous features found in both ancient and modern, shallowly buried, loose, and water-saturated sediments related to diverse depositional environments. Numerous triggering ...
Mesozoic break-up of SW Gondwana: Implications for regional hydrocarbon potential of the southern South Atlantic
(Elsevier, 2003-06)
This work provides new palinspastic palaeofacies reconstructions of SW Gondwana incorporating rotation of a Falkland/Malvinas microplate. We discuss the implications of this for the tectonic evolution of the southern South ...
Neoproterozoic tectonic and magmatic episodes in the NW sector of Borborema Province, NE Brazil, during assembly of Western Gondwana
(Pergamon-Elsevier B.V. Ltd, 2008-05-01)
The Medio Coreau domain of NE Brazil is located along the northwest margin of Borborema Province, the western branch of a Brasiliano/Pan-African collisional belt that formed during the assembly of Western Gondwana. The ...

The Medio Coreau domain of NE Brazil is located along the northwest margin of Borborema Province, the western branch of a Brasiliano/Pan-African collisional belt that formed during the assembly of Western Gondwana. The ...
Tracción de losa en el margen boreal del océano paleotetis y deformación en el interior de Gondwana (incluyendo el cordón plegado de Ventana)Slab pull in the northern margin of Paleothetys ocean and internal deformation in Gondwana (including Ventana fold belt)
(Asociación Geológica Argentina, 2015-09)
Durante el Paleozoico tardío tuvieron lugar varios procesos tectónicos en el interior de Pangea que generaron estructuras reconocidas en diferentes lugares de nuestro planeta. Con el objetivo de relacionar estos procesos ...
First late Ordovician paleomagnetic pole for the Cuyania (Precordillera) terrane of western Argentina: A microcontinent or a Laurentian plateau?
(Elsevier Science, 2004-12)
Time and tectonic processes involved in docking of the Argentine Precordillera. (Cuyania terrane) against SW Gondwana has been a matter of much debate. A paleomagnetic study on the Early Caradoc Pavón Formation, exposed ...
Inter- and intratill boulder pavements in the Carboniferous Hoyada Verde Formation of West Argentina: An insight on glacial advance/retreat fluctuations in Southwestern Gondwana
(Elsevier Science, 2016-04)
Two glacially abraded surfaces have been identified in the glaciomarine section of the Carboniferous Hoyada Verde Formation, Calingasta-Uspallata basin in west Argentina. The Glacial Erosion Surfaces (GES) found in the ...
