| Abstract | dc.description.abstract | The Villarrica-Quetrupillán-Lanín volcanic chain is surrounded by > 20 hot springs, located on the flanks and in the valleys around the volcanos. The hot springs that are extensively used for spa purpose discharge thermal water of intermediate temperatures (27° - 81°C), mostly alkaline pH and low mineralization. To investigate fluid origin and genesis of Villarrica geothermal system the thermal waters are analyzed for hydrochemical composition, δ18 O/δD isotopes and Sr/Sr isotope ratios. They are Na dominated indicating strong water-rock interaction. Anion composition varies significantly, without any clear spatial relationship. The majority of springs have similar concentrations of major anions spreading between the SO4-, bicarbonate- and Clendmembers. Magmatic degassing can be traced solely by slightly elevated B concentrations in springs around the volcanic chain. | |
