Abstract

A feasibility study was done to evaluate the Southwestern Tanzania geothermal prospects for their power potential. Vertical Electrical Sounding (VES), a geophysical survey method was deployed in this study. VES was done to study the vertical variations of electrical resistivity in the geothermal prospects and to locate the extent of the reservoir/ fracture zones or the outflow regime of the thermal waters. The result showed that at Na John, River-muddy, Bwana Hutu, Mampulo, Mwakalinga and Kasumulo springs (VES 1, 2, 3, 4, 5 and 6 respectively), the apparent resistivities decreased with depth as one moves from the first top layer to the second. It was noted that in VES 3, 4 and 6, the second layers have low resisti
