dc.description.abstractThis study presents the geophysical characterization of PMD of Mpanda Mineral Field in SW Tanzania. The study is based on high-resolution airborne geophysical data and ground electrical data aided by fieldwork works and petrophysical investigations. Low magnetic signatures possibly due to hydrothermal processes, moderate to high conductive bodies and high K alteration were observed to characterize the known gold bearing veins, base metal rich veins and gold and base metal deposits of D-reef, Kapanda, Magamba, Mpanda and Nsimbo deposits. High IP signatures, low resistivity in silica poor provinces and high resistivity over silicified ore bodies; and negative SP signatures coincided the known mineral deposits. However, there is no clear cut in geophysical signatures between the gold bearing veins, base metal rich vein, gold and base metal rich veins. They all exhibit the same geophysical signatures depending on either absence or presence of silica alteration. The host rocks were observed to exhibit magnetic highs, poor conductive signatures, and high resistivity in silica poor provinces, poor K alteration, positive SP signatures and low IP signatures.The low magnetic signatures were observed where faults and shear zones cut across the known gold rich veins, base metal, gold and base metal rich vein deposits. Superimposing these structures into AEM and radiometric images; and interpolating their existence on IP, resistivity and SP profiles, the structures controlling mineralization exhibited conductive signatures, high K alteration, high IP, low to high resistivity depending on alteration and negative SP signatures. The host structures exhibited high magnetic signatures, poor conductivity, and high resistivity in silica poor bodies, low IP and positive SP signatures.en_US
