Tardani, Daniele; Reich Morales, Martín; Roulleau, Emilie; Takahata, Naoto; Sano, Yuji; Pérez Flores, Pamela; Sánchez Alfaro, Pablo; Cembrano, José; Arancibia, Gloria (Elsevier, 2016)There is a general agreement that fault-fracture meshes exert a primary control on fluid flow in both volcanic/magmatic and geothermal/hydrothermal systems. For example, in geothermal systems and epithermal gold deposits, ...

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 Flores, Pamela; Veloso, Eugenio; Cembrano, José; Sánchez Alfaro, Pablo; Lizama, Martín; Arancibia, Gloria (Elsevier, 2017)In this study, we examine the fracture network of the Tolhuaca geothermal system located in the Southern Andean volcanic zone that may have acted as a pathway for migration and ascent of deepseated fluids under the ...

Wrage, Jackie; Tardani, Daniele; Reich Morales, Martín; Daniele, Linda; Arancibia, Gloria; Cembrano, José; Sánchez Alfaro, Pablo; Morata Céspedes, Diego; Pérez Moreno, Rodrigo (Elsevier, 2017)Thermal waters in the Southern Volcanic Zone (SVZ) of Chile between 36 degrees-41 degrees S were studied using major and selected trace element relationships to characterize their geochemistry, formation mechanisms, and ...

Sepúlveda, Fabián; Lahsen Azar, Alfredo; Bonvalot, Sylvain; Cembrano, José; Alvarado, Antonia; Letelier, Pablo (ELSEVIER SCIENCE BV, 2005-11-15)The Cordon Caulle geothermal region (40.5 degrees S) is a 13 km X 6 kin, NW-SE elongate, volcano-tectonic depression hosting numerous monogenetic volcanic centers, fumaroles, and hot-springs, most of which occur spatially ...

Sánchez Alfaro, Pablo; Arancibia, Gloria; Reich Morales, Martín; Pérez Flores, Pamela; Cembrano, José; Driesner, Thomas; Lizama, Martín; Rowland, Julie; Morata Céspedes, Diego; Heinrich, Christoph A.; Tardani, Daniele; Campos, Eduardo (Elsevier, 2016)In this study, we unravel the physical, chemical and mineralogical evolution of the active Tolhuaca geothermal system in the Andes of southern Chile. We used temperature measurements in the deep wells and geochemical ...

Pearce, R. K.; Sánchez de la Muela, A.; Moorkamp, M.; Hammond, J. O. S.; Mitchell, T. M.; Cembrano, J.; Araya Vargas, J.; Meredith, P. G.; Iturrieta, P.; Pérez Estay, N.; Marshall, N. R.; Smith, J.; Yánez, G.; Ashley Griffith, W.; Marquardt, C.; Stanton Yonge, A.; Núñez, R. (American Geophysical Union., 2020)In active volcanic arcs such as the Andean volcanic mountain belt, magmatically sourced fluids are channeled through the brittle crust by faults and fracture networks. In the Andes, volcanoes, geothermal springs, and ...

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. ...

Iturrieta, Pablo Cristián; Hurtado, Daniel E.; Cembrano, José; Stanton Yonge, Ashley (Elsevier, 2017)Orogenic belts at oblique convergent subduction margins accommodate deformation in several trench parallel domains, one of which is the magmatic arc, commonly regarded as taking up the margin-parallel, strike-slip component. ...

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 ...

Heuser, Gert; Arancibia, Gloria; Veloso, Eugenio E.; Cembrano, José; Oliveira Cordeiro, Pedro Filipe; Nehler, Mathias; Bracke, Rolf (Elsevier, 2020)The Fe-Cu Dominga deposit (2082 Mt at 23% Fe, 0.07% Cu), located in the Coastal Cordillera of northern Chile, is hosted by volcanic rocks of the Punta del Cobre Formation (131.5 +/- 1.5 Ma zircon U-Pb) and into subvolcanic ...
