Molina, Eduardo; Arancibia, Gloria; Sepúlveda, Josefa; Roquer, Tomás; Mery, Domingo; Morata Céspedes, Diego (Springer, 2020)The Southern Volcanic Zone of the Andes has a high potential in terms of geothermal resources and is an exceptional and poorly explored natural laboratory to study the interplay between tectonic stresses, thermal damage, ...

Roquer, Tomás; Arancibia, Gloria; Rowland, Julie; Iturrieta, Pablo; Morata Céspedes, Diego; Cembrano, José (Elsevier, 2017)Paleofluid-transporting systems can be recognized as meshes of fracture-filled veins in eroded zones ofextinct hydrothermal systems. Here we combined meso-microstructural analysis of 107 fractures andmechanical modeling ...

Pérez Estay, Nicolás; Yáñez, Gonzalo; Crempien, Jorge; Roquer, Tomás; Cembrano, José; Valdenegro, Pablo; Aravena, Diego; Arancibia, Gloria; Morata Céspedes, Diego (Amer Geophysical Union, 2020)Understanding the relationship between crustal faults and volcanic activity in transpressional environments is a main goal in geosciences and could help to understand geothermal resources and evaluate geological hazards. ...

Pérez Flores, Pamela; Cembrano, José; Sánchez Alfaro, Pablo; Veloso, Eugenio; Arancibia, Gloria; Roquer, Tomás (Elsevier, 2016)This study addresses the interplay between strain/stress fields and paleo-fluid migration in the Southern Andean Volcanic Zone (SVZ). The SVZ coexists with the margin-parallel Liquine-Ofqui Fault System (LOFS) and with ...

Roquer, Tomás; Arancibia, Gloria; Rowland, Julie; Veloso, Eugenio A.; Molina, Eduardo; Crempien, Jorge G. F.; Morata Céspedes, Diego (Pergamon-Elsevier, 2020)Fracture opening at low differential stress controls maximum sustainable fluid pressure (lambda) within cohesive brittle crust. Standard Andersonian stress states occur when two conditions are met: (1) one of the principal ...

Sepúlveda, J.; Arancibia Hernández, Gloria; Molina, Eder; Gilbert, J. P.; Duda, M.; Browning, Julianna; Roquer, Tomás; Morata Céspedes, Diego; Ahrens, Bodo; Bracke, Rolf (Elsevier, 2020)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 ...
