Several African countries, particularly those with substantial mineral deposits, are marked by low economic progress and unstable institutions. This study aims to explore the effects of mineral resource rents and renewable energy consumption on real economic growth across eight countries in the East and...
The rock units exposed in the Jabal Hamadat area are presented in chronological order (Fig. 2), with the youngest formations listed as follows: (1) Recent wadi deposits: consisting of beach and wadi gravel deposits, silt and sandy bands, and remnants of coral reefs. (2) Old alluvium: ...
Uranium concentrations from four major phosphate rocks and four commonly used phosphate fertilizer types in East Africa were determined. The study involved phosphate rocks collected from the following deposits: Matongo (Burundi), Minjingu (Tanzania), Mrima Hill (Kenya), and Sukulu Hill (Uganda). ...
Particularly interesting is the flexible and on-demand integration pathway in the Finnish zoning plans: Zoning plans can be ‘reformulated’ (flexible) based on land-use processes in case new deposits are discovered or re-evaluation of existing deposits (on-demand) becomes necessary. The only case...

The Mineral Policy Act granted 10-year leases for the right to extract publicly owned deposits of oil and minerals. The general principle was that the leases would be awarded based on a competitive bidding process. However, there were irregularities of which Teapot Dome Scandal was one of the ...
Kajjansi and Ntawo clay depositsWe analyzed the mineralogical and chemical (including rare earth element [REE]) composition of the >63, 32–63, and <32 μm grain-size fractions of clay-rich sediments from Kajjansi and Ntawo valleys, central Uganda. This was done to understand the changes ...
For several months, the rebels have also controlled Rubaya, a mining town in North Kivu that harbors one of the world’s largest coltan deposits. This valuable mineral is used in the production of mobile phones. Bintou Keita, who heads the UN mission in DR Congo, told the Security Council...
