Caracterización geoquímica y petrográfica del sector La Fortuna en la concesión minera Los Santos 2.1

Abstract

Abstract: This titling work is based on the geochemical and petrographic characterization of the La Fortuna sector, located in the Atahualpa canton of the Oro province. The purpose of this work is to identify and define mineralized zones. The exploration was based on the sampling of soils and rocks (outcrops). For the identification of possible mineralized deposits, mineralogical and chemical analyzes were carried out, as well as geostatistical studies. The analyzes performed were: ICP-OES, microscopic descriptions of thin slices and polished sections. The data obtained allowed us to identify gold and silver mineralizations in the hydrothermal veins and an anomaly of copper in soils and in a hydrothermal breccia. In addition, the elaboration and interpretation of thin sheets, determined three lithologies: schist to the south of the area, meta andesite in the center of the area and granodiorite to the north of the study area and with all this information it was possible to propose 7 drilling wells to define zones enriched.
