The interplay between a heat source, primary plus secondary permeability, and
hydrothermal fluids makes geothermal systems a highly dynamic environment where …

This study focuses on hydrothermal alteration in the geothermal reservoir of Cerro Pabellón
(Andean Cordillera, Northern Chile). It is based on CP2A and CP5A production wells drilled …

Thermal waters in the Southern Volcanic Zone (SVZ) of Chile between 36°–41° S were
studied using major and selected trace element relationships to characterize their …

Detailed mineralogical analyses in areas with surface hydrothermal alteration zones
associated with recent volcanism (< 1 Ma) in the Central Andean Volcanic Zone could …

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 …

Two distinct domains of the geothermal systems, viz. structural (or non-volcanic) and
volcanic have been identified in the southcentral Chile, based on the chemistry of the …

Investigating, from surface, deep-seated geothermal systems below hundreds to thousands
of meters of thick clastic and unconsolidated sediments is always a timely theme for …

Sulphate, clay, silica and oxide-hydroxide minerals were identified by means of fieldwork,
XRD and SEM, both in the active and fossil zones of the Cerro Apacheta volcano (Cerro …

The main characteristics of geothermal systems at flat-slab segments are not well
understood. This work reports a geological and fluid geochemistry survey at the southern …

Abstract Southern Volcanic Zone (SVZ) hosts numerous thermal springs (25–85° C), related
to Liquiñe-Ofqui Fault System (LOFS) and Andean Transverse Faults (ATFs), suggesting the …
