    • Fault-controlled development of shallow hydrothermal systems: Structural and mineralogical insights from ... 
      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 ...
    • Physical, chemical and mineralogical evolution of the Tolhuaca geothermal system, southern Andes, Chile: ... 
      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 ...
    • The effect of axial stress in maximum sustainable fluid pressure in Andersonian and non-Andersonian crust: ... 
      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 ...
    • The optimal windows for seismically-enhanced gold precipitation in the epithermal environment 
      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 ...
