A synthesis of palynological data recovered from “Neocomian” deposits of the Golfo San Jorge Basin

Latin American Journal of Sedimentology and Basin Analysis
This contribution provides a synthesis of the palynological studies carried out on “Neocomian” units of the Golfo San Jorge Basin. Additionally, a revision of the palynological zones established for these units in previous works is presented ...

Expanding knowledge of hothouse conditions through the study of paleosols in the southern Golfo San Jorge Basin

Latin American Journal of Sedimentology and Basin Analysis
Hothouse periods, such as the mid-Cretaceous and early Eocene, were times of global warming with high levels of greenhouse gases, elevated temperatures, and ice-free poles that provide a case study for understanding past climate dynamics.

Paleoecology and paleoenvironments of Podocarp trees in the Ameghino Petrified forest (Golfo San Jorge Basin, Patagonia, Argentina): Constraints for Early Paleogene paleoclimate

Geologica Acta, 2011
During the Early Paleocene (Danian), Central Patagonia had a warm-temperate climate and was dominated by evergreen coniferous forests. Abundant permineralized conifer woods along with some dicot and palm leaf compressions were found in the Ameghino ...

A method for estimation of hydrologycal sensibility applied in Golfo San Jorge basin. Province of Chubut. Argentina

Boletín Geológico y Minero, 2009
A method developed and used in an area of Chubut Province is described. The object of the method is to determine the underground andsurficial hydrological sensitivity in order to select the site of petroleum facilities with the least possible environmental hydric risk. It isbased on the conjunction of the GOD method used to assess the intrinsic aquifer
