Crude oils from Austral and Golfo San Jorge Basins. Similarity and differences based on Biomarker Ratios

Dyna, 2021
The biomarker profiles are characteristic of oils. The goal of this study was to evaluate the biomarkers in oil samples using geochemical analysis. Oil samples were obtained from Austral Basin and from Golfo San Jorge Basin.

Structural framework and evolution of the Golfo San Jorge Basin: a synthesis

Latin American Journal of Sedimentology and Basin Analysis
The 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 ...

Late Pleistocene and Holocene transgression inferred from the sediments of the Gulf of San Jorge, central Patagonia, Argentina

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

Sr ages for the Chenque Formation in the Comodoro Rivadavia region (Golfo San Jorge Basin, Argentina): Stratigraphic implications

Latin American Journal of Sedimentology and Basin Analysis, 2021
The age and stratigraphic subdivisions for the late Oligocene-Miocene, marine deposits of Patagonia (Patagoniense succession) have been largely debated. Most studies for the Comodoro Rivadavia region were focused on its biostratigraphy and stratigraphic

Control of crustal strength, tectonic inheritance, and stretching/ shortening rates on crustal deformation and basin reactivation: insights from laboratory models [PDF]

Solid Earth, 2022
Geological settings characterized by multiple coeval tectonic regimes provide a unique opportunity to understand complex interactions among different geodynamic processes. However, they remain comparatively less studied from an experimental point of view

TURTLES FROM THE MATA AMARILLA FORMATION (CENOMANIAN), SANTA CRUZ, ARGENTINA: THE SOUTHERMOST RECORD OF PROCHELIDELLA SPP. (PLEURODIRA: CHELIDAE)

Publicación Electrónica de la Asociación Paleontológica Argentina, 2022
The fossil record of Cretaceous turtles in Santa Cruz Province is scarce. Turtles have been reported from the Mata Amarilla Formation (Cenomanian), the Cerro Fortaleza Formation (Campanian–Maastrichtian), and the Chorrillo Formation (early Maastrichtian).

Climatic signals in lacustrine deposits of the Upper Yacoraite Formation, Western Argentina: Evidence from clay minerals, analcime, dolomite and fibrous calcite

Sedimentology, Volume 67, Issue 5, Page 2282-2309, August 2020., 2020
Abstract Authigenic clays are an important control on reservoir quality in lacustrine carbonates but remain challenging to predict. Lacustrine depositional systems respond to climatic variations in rainfall, surface runoff and groundwater input, and evaporation, and result in rapid and frequent changes in lake volume; this is expressed through changing

Explosive Volcanism in a tuff-dominated Intraplate Setting, Sarmiento Formation (Middle Eocene- lower Miocene), Patagonia Argentina

Latin American Journal of Sedimentology and Basin Analysis, 2021
The Sarmiento Formation (middle Eocene to early Miocene) represents the distal record of the activity of the Andean volcanic arc in central Patagonia, mainly dominated by accumulation and reworking of fine ash in a low-gradient continental setting ...

Photo‐identification and satellite telemetry connect southern right whales from South Georgia Island (Islas Georgias del Sur) with multiple feeding and calving grounds in the southwest Atlantic

Marine Mammal Science, Volume 40, Issue 2, April 2024.
Abstract The sub‐Antarctic waters of South Georgia Island (Islas Georgias del Sur, SG/IG) are a regularly visited feeding ground for southern right whales (Eubalaena australis, SRW) in the southwest Atlantic. Satellite telemetry and photo‐identification records were compared to better understand the role of SG/IG in the SRW migratory network.
