The Andes Cordillera resulted from the interaction of the Nazca Plate and the South American Plate. The subduction process occurring between both plates has controlled all geological evolution of such territory since ...

The Andean volcanic arc includes over 200 active stratovolcanoes and at least 12 giant caldera systems. Nevertheless, there is not a standard procedure for estimating geothermal resources associated with unexplored volcanic ...

Magnetotelluric (MT) data were recorded to investigate a geothermal prospect in northern Chile. The exploration area is located in the Atacama region, at the southern edge of the Chilean Altiplano, at an altitude of similar ...

The Villarrica-Quetrupillán-Lanín volcanic chain is surrounded by > 20 hot springs, located on the flanks and in the valleys around the volcanos. The hot springs that are extensively used for spa purpose discharge thermal ...

The reconstruction of the stratigraphical-structural framework and the hydrogeology of geothermal areas is fundamental for understanding the relationships between cap rocks, reservoir and circulation of geothermal fluids ...

Fractures and faults in granitic rocks play an important role in geothermal systems because they permit the circulation of hot fluids. However, the thermo-hydro-mechanical behavior of granitic rocks has predominantly been ...
