Uran-Prospektion in der Bundesrepublik Deutschland

Two deposits that can be considered economically minable have been found during the last twenty years of prospecting for uranium in the Federal Republic of Germany. These deposits, Menzenschwand and Müllenbach, are situated in the northern and southern Black Forest, respectively. In addition, favorable indications have been found in Paleozoic granites of northeastern Bavaria, of the Black Forest, and Odenwald, as well as in Permian and Triassic sediments of Rheinland-Palatinate, Franconia, and Württemberg. The uranium resources that can be expected from all these deposits are insufficient to meet the domestic demand.
