Contribution of ERT on the Study of Ag-Pb-Zn, Fluorite, and Barite Deposits in Northeast Mexico

The results on the effectiveness of five 2D electrical resistivity tomography (ERT) survey profiles for Ag-Pb-Zn, fluorite, and barite exploration Mississippi Valley Type (MVT) magmatic deposits northeast Mexico, are presented. were made in areas with mining activities or mineralization outcrops. Schlumberger, dipole-dipole, Wenner array configurations used measurements. showed that electric can be to distinguish between mineralized zones. In magmatic-type Pb-Zn MVT deposits, values shown as low. fluorite well deposit, low-resistivity related Fe sulfides clays. With these it is possible connect observed surface underground mineralization. New zones also found their geometries, extensions, dipping reported. Therefore, lower linked mineral bodies higher Ag-Pb-Zn contents, enriched sulfides, oxides, clays mineralizations. most ERT models, fractures faults identified, indicating a structural control From geoelectric patterns we infer origin deposits.
