Prospecção Geofísica de Água Subterrânea em Xinguara/PA Aplicação do Método HLEM em Meio Cristalino

Electromagnetic methods have been successful when applied for ground water survey in metamorphic and igneous terrains, especially if perfectly combined with information of structural components. During the research done in Xinguara, in the Southeast of Para, Brazil, HLEM profiles were run in the transversal direction of both the fractures and the foliation. Even though the fractures didn’t seem to be opened, the high foliation dips must have deepened the intemperism, creating vertical bodies with promising permo-porosity for water infiltration and aquifers formation.
