Geochemistry of fluid discharges from Peteroa volcano (Argentina-Chile) in 2010-2015: Insights into compositional changes related to the fluid source region(s)
(Elsevier Science, 2016-04)
This study presents the first geochemical data of fluid discharges collected from February 2010 to March 2015 from the Planchón–Peteroa–Azufre Volcanic Complex (PPAVC), located in the Transitional Southern Volcanic Zone ...
Geochemistry of thermal waters in the Southern Volcanic Zone, Chile – Implications for structural controls on geothermal fluid composition
(2017)
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 geochemistry, formation mechanisms, and to explore the ...
Abanico East Formation: petrology and geochemistry of volcanic rocks behind the Cenozoic arc front in the Andean Cordillera, central Chile (33°50'S)
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2006)
Chemical and isotopic features of cold and thermal fluids discharged in the Southern Volcanic Zone between 32.5 degrees S and 36 degrees S: Insights into the physical and chemical processes controlling fluid geochemistry in geothermal systems of Central Chile
(Elsevier, 2016)
The Principal Cordillera of Central Chile is characterized by two belts of different ages and lithologies: (i) an eastern Mesozoic belt, consisting of limestone- and gypsum-rich sedimentary rocks at the border between ...
Jurassic to Early Cretaceous subduction-related magmatism in the Coastal Cordillera of northern Chile (18 degrees 30 '-24 degrees S): geochemistry and petrogenesis
(2007)
Jurassic to Early Cretaceous magmatism in the Coastal Cordillera of northern Chile is represented by thick sequences of mostly basaltic- and esitic to andesitic lava flows and minor sedimentary rocks. The volcanic sucession ...
The geochemistry of apatite from the Los Colorados iron oxide–apatite deposit, Chile: implications for ore genesis
(Springer Verlag, 2019)
Apatite grains from the Los Colorados iron oxide–apatite (IOA) deposit, the largest IOA deposit in the Chilean Iron Belt (CIB), exhibit significant intracrystalline spatial variability with respect to the concentrations ...
Geochemistry of metals and metalloids in siliceous sinter deposits: Implications for elemental partitioning into silica phases
(2017)
Sinter deposits are formed by precipitation of silica from hydrothermal fluids that have reached the surface environment. They are commonly found around hot springs and represent surface expressions of underlying geothermal ...
