Ibadakuli geothermal site lies within the sukumaland greenstone belt in the Archean Nyanzian Greenstone belt of Lake Victoria goldfield. The area is a lowland and swampy, dominated by alluvial sand, with significant composition of quartz, as a result of weathering of felsic units, probably from basement complex of granitoid.
2.Mtagata geothermal site
The site is located in Rwabigaga village in Kamuli ward, Mabira division, Kyerwa district in Kagera region.
