Petrological Model of Berlin Geothermal Field, El Salvador Based on Fluid Inclusion Studies

Abstract

Summary Fluid inclusions studies have been undertaken in Berlin geothermal field, El Salvador since 2001 as part of the training given by IAEA. From then on, interest in this field has been focused. With the proper training from well-known institutions like Italy and USA, Lageo acquired its fluid inclusion system in 2012. Several temperature measurements (Th and Tf) were done and in collaboration with CNR of Italy, a petrological model was constructed in Berlin geothermal field. The model correlates well with geochemistry and reservoir models, where the hottest temperature is located at the TR-4 and TR-5 zones. The outflow zone was also delimited by fluid inclusion studies.
