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
