(Society of Economic Geologists (SEG), 2020)Pyrite is ubiquitous in the world-class iron oxide copper-gold (IOCG) deposits of the Candelaria-Punta del Cobre district, documented from early to late stages of mineralization and observed in deep and shallow levels of ...
-
(Elsevier Ltd, 2019)© 2018 Elsevier Ltd The chemical composition, textures and mineral associations of pyrite provide key information that help elucidate the evolution of hydrothermal systems. However, linking the compositional and micro-textural ...

(Springer-Verlag, 1979)Seventeen granitoid samples from batholiths in central Chile (33 °-34 ° S) have been analyzed for trace element content. The samples range in age from Paleozoic to Tertiary, and in rock type from quartz diorite to granite. ...
-
(Elsevier, 2018-07)Besides temperature, mineralogy, residence time and dilution are crucial for assessing water-rock interaction intensity. The geothermal system at the Villarrica-Quetrupillan-Lanin volcanic chain, Southern Chile, is located ...

(ELSEVIER SCIENCE BV, 2005-06)The Central Atlantic Magmatic Province (CAMP) is one of the largest igneous provinces on Earth, extending more than 5000 km north to south, on both sides of the Atlantic Ocean. Its emplacement occurred about 200 Ma ago, ...
-
(PERGAMON-ELSEVIER SCIENCE, 2005-03)Geochemical data from basalts, basaltic andesites, and andesites of the Mesozoic-Cenozoic (143-44 Ma) from Livingston, Greenwich, Robert, King George, and Ardley Islands of the South Shetland archipelago, Antarctica, are ...
-
(Elsevier, 2016)This study presents the first geochemical data of fluid discharges collected from February 2010 to March 2015 from the Planchon-Peteroa-Azufre Volcanic Complex (PPAVC), located in the Transitional Southern Volcanic Zone ...
-
(Elsevier, 2018)The Manantiales Foreland Basin, located at similar to 32 degrees 15'S in the Frontal Cordillera, Argentina, contains the sedimentary record of erosion of igneous basement and Miocene volcanic rocks exhumed during the Andean ...
-
(Elsevier, 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 ...
-
(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 ...
