3D Geoelectrical Resistivity Mapping of Tourmaline-Rich Pegmatite in AngwanDoka, Nassarawa State, Northcentral Nigeria

Abstract: 3D geoelectrical resistivity survey was carried out using the Multiple Vertical Electrical Sounding (MVES) along profile lines to determine the extent of mineralized tourmaline-rich pegmatite within a mining site in AngwanDoka community in Kokona Local Government Area, Nassarawa State, Nigeria. A total of 61 out of 90 soundings within a grid area which covered 200m2 were selected for convenience of modeling. Resistivity data were modeled using a combination of manual curve matching, data inversion and iteration with IP2WIN software, and 3D data modeling using rockworks software. This integrated approach with a resulting 3D model revealed a major trend of the pegmatite in the NE-SW direction which is in line with the overall regional structural strike in the region. The method can therefore be applied extensively for other related subsurface resistivity investigations.
