Growth pattern of the Tehuelche and Mapuche ethnic population groups of the rural districts of Chubut, South Patagonia, Argentina

International Journal of Anthropology, 2002
This investigation is aimed at recording the conditions of life and of reproduction of the population of the rural districts of the Province of Chubut, in South Patagonia. These districts, where in 1991 more than 50% of the population lived in towns of less than 2000 inhabitants, have an important indigenous component of the Tehuelche and Mapuche ...

Comparative structural analysis of inverted structures in the San Bernardo fold belt (Golfo San Jorge basin, Argentina): Inversion controls and tecto-sedimentary context of the Chubut Group

Journal of South American Earth Sciences, 2020
Abstract The Golfo San Jorge Basin is one of the most important hydrocarbon-bearing basins of Argentina. Its position in the distal Patagonian Broken Foreland confers a particular structural architecture. Specifically, the western margin was affected by positive tectonic inversion, with higher degrees of inversion at the San Bernardo Fold Belt (SBFB).

Patterns and origins of the porosity in the productive reservoirs of the upper part of the Chubut Group, southern flank of the Golfo de San Jorge Basin, Patagonia Argentina

Journal of South American Earth Sciences, 2020
Abstract The Mina del Carmen, Bajo Barreal and Canadon Seco Formations bear the most important Cretaceous reservoirs in the southern flank of the Golfo de San Jorge Basin, in which the porosity is mainly secondary in origin. Primary porosity is about 4% in average and can be divided in intergranular and intercrystalline porosity, the former is better

Sandstone petrography and provenance of the Chubut Group (Cretaceous) in the Matasiete Canyon (Golfo San Jorge Basin, central Patagonia): implication for basin evolution and alluvial organization

2020
Sandstone petrographic data have been used to investigate the provenance of the Matasiete, Pozo D-129, and Castillo formations (Chubut Group) in the Cañadón Matasiete, San Bernardo Fold Belt at Golfo San Jorge Basin, Argentina. Available petrographical data provides evidence of several distinctive volcanic source areas, with minor contributions of ...
