oa Geophysical Investigation of the Subsurface Structures of the Usangu Basin Based on Gravity and Aeromagnetic Data

The Usangu basin is among the rift basins that have been developed along the western arm of the Cenozoic East African rift system (EARS) during the Pliocene-Pleistocene epochs. The basin is stationed at the Mbeya triple junction and seismically active zone with high heat flow as emanated by geothermal activities. These activities triggered the formation of different basement structures and their response on sedimentary portion. To investigate these structures and the variation of sediment thickness along the basin, the magnetic and gravity data in conjunction with SRTM data were used.
