Abstract
An integrated geophysical interpretation has been conducted around La Selva basin that show strong geochemical and geologic evidences of hydrothermal with the intent of define a conceptual model for exploration of low and intermediate enthalpy geothermal resources. The geophysical data involved in this study consist of gravity, magnetic and geoelectrical, supplemented by geological and hydrogeochemical information. The interpretation of gravity anomalies has been useful for defining the main structural discontinuities, magnetic map show the existence of several anomalies related to mafic intrusions while geoelectrical prospecting let delineate more conductive areas which could correspond to an increase in thermal fluid circulation. The results obtained by the different geophysical methods are in good agreement and allows defining a reliable geostructural model of the subsurface of the studied area.
