    • Copper-arsenic decoupling in an active geothermal system: a link between pyrite and fluid composition 
      Tardani, Daniele; Reich Morales, Martín; Deditius, Artur P.; Chryssoulis, Stephen; Sánchez Alfaro, Pablo; Wrage, Jackie; Roberts, Malcolm P. (Elsevier, 2017-05-01)
      Over the past few decades several studies have reported that pyrite hosts appreciable amounts of trace elements which commonly occur forming complex zoning patterns within a single mineral grain. These chemical zonations ...
    • Exploring the structural controls on helium, nitrogen and carbon isotope signatures in hydrothermal fluids ... 
      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, ...
    • Geochemistry of thermal waters in the Southern Volcanic Zone, Chile - implications for structural controls ... 
      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 ...
    • 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 ...
    • Tectonics, magmatism and paleo-fluid distribution in a strike-slip setting: Insights from the northern ... 
      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 ...
    • 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 ...
    • Trace element signature of pyrite from the los colorados iron oxide-apatite (ioa) deposit, chile: a missing ... 
      Reich Morales, Martín; Simon, Adam C.; Deditius, Artur P.; Barra, Fernando; Chryssoulis, Stephen; Lagas, Gonzalo; Tardani, Daniele; Knipping, Jaayke L.; Bilenker, Laura; Sánchez Alfaro, Pablo (Soc Economic Geologists, 2016)
      Although studies have proposed that iron oxide-apatite (IOA) deposits may represent the deeper roots of some Andean iron oxide copper-gold (IOCG) systems, their genetic links remain obscure and controversial. A key ...
