Structural framework and evolution of the Golfo San Jorge Basin: a synthesis
Latin American Journal of Sedimentology and Basin AnalysisThe Golfo San Jorge Basin evolved through a complex multiphase structural history from the Middle Jurassic to the Neogene. Its stratigraphic record captures key tectonic events in central extra-Andean Patagonia during Gondwana fragmentation and the ...

Sedimentary Geology, 2013 Abstract The Upper Paleocene Rio Chico Formation is a 50–180 m thick fluvial succession developed in a passive-margin setting, Golfo San Jorge basin, Central Patagonia, Argentina. A detailed description and interpretation of outcrops was carried out, analyzing exposures from the northern basin margin to the most complete successions at the southern ...

Sedimentary Geology, 2008 Abstract Paleocene sedimentary rocks in the Golfo San Jorge Basin include the marine Salamanca Formation and the continental Rio Chico Formation. Both units contain soft-sediment deformation features and evidence of contemporary tectonics, which include: 1) sediment-filled fissures, hosted in muddy marine sediments of the Salamanca Formation ...

Journal of Quaternary Science, Volume 38, Issue 5, Page 629-646, July 2023., 2023 ABSTRACT This study presents the first detailed description of the upper sedimentary succession of the late Pleistocene and Holocene deposits in the Gulf of San Jorge (Patagonia) based on several hundred kilometers of high‐resolution seismic (sparker) profiles and numerous sediment cores. High‐resolution seismic stratigraphy confirms the existence of a
