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

ERT对墨西哥东北部Ag-Pb-Zn，萤石和重晶石矿床研究的贡献

提出了关于五种二维Ag-Pb-Zn，萤石和重晶石勘探密西西比河谷类型（MVT）的二维电阻层析成像（ERT）有效性以及墨西哥东北部的岩浆矿床的结果。剖面图是在具有采矿活动或矿化露头的地区制作的。测量中使用了斯伦贝谢，偶极-偶极和Wenner阵列配置。结果表明，电阻率可用于区分矿化带。在岩浆型Pb-Zn和MVT Pb-Zn矿床中，电阻率值显示为低。在岩浆型萤石和MVT萤石矿床以及MVT重晶石矿床中，低电阻率值与硫化铁和粘土有关。利用这些结果，可以将观察到的地表矿化与地下矿化联系起来。还发现了新的矿化带，并报告了它们的几何形状，延伸和倾角。因此，较低的电阻率值可以与具有较高Ag-Pb-Zn含量的矿体以及萤石和重晶石矿化中富含Fe硫化物，Fe氧化物和粘土的矿体相关。在大多数ERT模型中，可以识别出裂缝和断层，表明对矿化的结构控制。从地电模式，我们可以推断出这些矿床的岩浆和MVT成因。识别出裂缝和断层，表明对矿化的结构控制。从地电模式，我们可以推断出这些矿床的岩浆和MVT成因。识别出裂缝和断层，表明对矿化的结构控制。从地电模式，我们可以推断出这些矿床的岩浆和MVT成因。
