Jonas Mgundulwa Mwano Libri

The book explores the untapped geothermal potential of the East African Rift region, highlighting that despite a capacity exceeding 10,000 MWe, only Kenya and Ethiopia are currently utilizing geothermal energy. It identifies key challenges, such as a lack of trained personnel and modern exploration tools, that hinder development in countries like Tanzania, Uganda, Eritrea, and Djibouti. By addressing local training needs and increasing awareness among policymakers, the book aims to facilitate the growth of geothermal energy in the region.

In Kalenga area, the surface and subsurface geology of the area is not well understood for many years due to superficial covers and extensive swamps. Integrated interpretation of aerogeophysical and satellite image data were used to delineate the concealed lithology into five geological units; Nyanzian granite-greenstone belt, the Karagwe-Ankolean Supergroup, the Bukoban group, the younger sediments of the Uha group and superficial deposits (mbuga), chocolate brown soils and laterites.Two major dyke swarms of probable Proterozoic age (1350 Ma) have been characterized using airborne magnetic data. The dyke swarms are NE-SW and NNE-SSW. The quantitative interpretations of the dyke swarms deduced that the dip angles vary in the order of 16 - 50 dipping towards NW. The geological boundaries of the three tectonic domains of the Nyanzian Supergroup, the Karagwe-Ankolean Supergroup and the Bukoban group have been elucidated. The results of this study has demonstrated the effectiveness of using digital integration based on satellite images and aerogeophysical data in systematic surface and subsurface geological mapping in developing countries such as Tanzania.
