Tectonics, magmatism and paleo-fluid distribution in a strike-slip setting: Insights from the northern termination of the Liquiñe–Ofqui fault System, Chile

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 ...

Fault-controlled development of shallow hydrothermal systems: Structural and mineralogical insights from the Southern Andes

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 ...

Geochemistry of thermal waters in the Southern Volcanic Zone, Chile - implications for structural controls on geothermal fluid composition

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 ...

Reactivation of fault systems by compartmentalized hydrothermal fluids in the southern Andes revealed by magnetotelluric and seismic data

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 ...

Exploring the shallow geothermal resources in the Chilean Southern Volcanic Zone: Insight from the Liquine thermal springs

Daniele, Linda; Taucare Toro, Matías; Viguier, Benoît; Arancibia Hernández, Gloria; Aravena Noemi, Diego; Roquer, Tomás; Sepúlveda Araya, Josefa; Molina, Eduardo; Delgado, Antonio; Muñoz Díaz, Mauricio; Morata Céspedes, Diego (Elsevier, 2020)

Southern Volcanic Zone (SVZ) hosts numerous thermal springs (25-85 degrees C), related to Liquine-Ofqui Fault System (LOFS) and Andean Transverse Faults (ATFs), suggesting the feasibility of low- to high-enthalpy geothermal ...

Reactivation of Fault Systems by Compartmentalized Hydrothermal Fluids in the Southern Andes Revealed by Magnetotelluric and Seismic Data

Pearce, R. K.; Sanchez de la Muela, A.; Moorkamp, M.; Hammond, J. O. S.; Mitchell, T. M.; Cembrano, J.; Araya Vargas, J.; Meredith, P. G.; Iturrieta, P.; Perez-Estay, N.; Marshall, N. R.; Smith, J.; Yanez, G.; Ashley Griffith, W.; Marquardt, C.; Stanton-Yonge, A.; Nunez, R. (2020)

Multi-scale flow structure of a strike-slip tectonic setting: A self-similar model for the Liquine-Ofqui Fault System and the Andean Transverse Faults, Southern Andes (39-40 degrees S)

Roquer, Tomas; Arancibia, Gloria; Crempien, Jorge G. F.; Mery, Domingo; Rowland, Julie; Sepulveda, Josefa; Veloso, Eugenio E.; Nehler, Mathias; Bracke, Rolf; Morata, Diego (PERGAMON-ELSEVIER SCIENCE LTD, 2022)

The flow structure of a brittle crustal volume is defined by the multi-scale geometric and hydraulic properties of its fracture meshes. The length density distribution n(L,l) and the transmissivity distribution K(L,l) ...
