Aplicação de métodos geoelétricos e gamaespectrométricos na identificação de zonas hidrotermais em Lavras do Sul – RS

Abstract

The study area is located geologically in the nucleus of the Intrusive Complex Lavras do Sul (CILS), climbs two lithologies. Previous studies in the area show great research potential for hydrothermal zones. Based on this, this work used aerogeophysical data on a regional and detail scale to obtain more information about probable hydrothermal zones in the area. Gamaespectrometric maps (K, U, Th and Factor F) generated information about possible areas of hydrothermal alteration and together with the data of the geoelectric survey it was possible to evaluate discontinuity in the structures. Based on the integration of geophysical data, areas with great potential for hydrothermal alterations were defined.
