Shallow anatomy of hydrothermal systems controlled by the Liquin?e-Ofqui Fault System and the Andean Transverse Faults: Geophysical imaging of fluid pathways and practical implications for geothermal exploration
(PERGAMON-ELSEVIER SCIENCE LTD, 2022)
We combined geoelectric and seismic ambient noise methods to image the shallow depth (<30 m) distribution of thermal waters in two fault-controlled hydrothermal systems located in southern Chile. The bedrock depth was ...
Tectonics, magmatism and paleo-fluid distribution in a strike-slip setting: Insights from the northern termination of the Liquiñe–Ofqui fault System, Chile
(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
(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 ...
Reactivation of fault systems by compartmentalized hydrothermal fluids in the southern Andes revealed by magnetotelluric and seismic data
(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 ...
The effect of axial stress in maximum sustainable fluid pressure in Andersonian and non-Andersonian crust: A field-based numerical study from the Southern Andes (39 degrees S)
(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 ...
Geochemistry of thermal waters in the Southern Volcanic Zone, Chile - implications for structural controls on geothermal fluid composition
(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
(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 major ...
Visualizing preferential magmatic and geothermal fluid pathways via electric conductivity at Villarrica Volcano, S-Chile
(Elsevier, 2020)
Preferential fluid pathways along regional fault systems are crucial for the spatial localization of volcanic and geothermal manifestations. Differences in electric properties of fluids and hydrothermal alteration products ...
