Bozzo Navarrete, Sergio; Arancibia Salvo, Claudia; Contreras Reyes, Daniel Ignacio; Pérez González, Leonardo (Sociedad Médica Santiago, 2020)Background: Practice is essential in clinical training and can be carried out with simulations. The medical school of the University of Chile performs Objective Structured Clinical Examinations (OSCE) using standardized ...

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, ...

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 ...

Gomila, Rodrigo; Arancibia, Gloria; Mery, Domingo; Nehler, Mathias; Bracke, Rolf; Morata Céspedes, Diego (Elsevier, 2019)Fault zone permeability and the real 3D-spatial distribution of the fault-related fracture networks are critical in the assessment of fault zones behavior for fluids. The study of the real 3D-spatial distribution of the ...

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 ...

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 ...

Sánchez Alfaro, Pablo; Reich Morales, Martín; Driesner, Thomas; Cembrano, Jose; Arancibia, Gloria; Pérez Flores, Pamela; Heinrich, Christoph A.; Rowland, Julie; Tardani, Daniele; Lange, Dietrich; Campos, Eduardo (Elsevier Science BV., 2016)Epithermal gold (Au) deposits result from the combination of a sustained flux of metal-rich fluids and an efficient precipitation mechanism. Earthquakes may trigger gold precipitation by rapid loss of fluid pressure but ...
