dc.description.abstract | Lake Magadi area of the Kenya Rift is characterized by faulting, tectonic activities and geothermal
resources. The geothermal potential of the graben in the southern part of the lake was investigated using
magnetic methods (ground and airborne). This was done to determine the geometry of tectonic faults and
ascertain their influence on the flow of hot springs, which are manifested on the surface. Five N-S faults
were identified for ground investigation using ground magnetic survey. Magnetic data were processed
using vertical derivatives, analytical signal and Euler deconvolution. The faults were further mapped with
aeromagnetic data using 2D Euler deconvolution. Magnetic derivative grids and profiles revealed
subsurface faulting/tectonic activities up to a depth of 400m and the presence of fluid-filled zones within
the basin, which are marked by the absence of magnetic sources. A deeper investigation into the
lineaments from the aeromagnetic data showed that the surface faults extend into a depth of 7.5 km in
the subsurface. The alignment of magnetic sources at the rift axis showed that these faults are probably
the parallel faults which bound the basin/graben to the west and to the east. The N-S faults structures in
the south of the lake serve as conduits for fluids which support the upward flow of the hydrothermal fluid
along its margin. | en_US |
