Uranium concentrations of soils, and their use for prospection . U 3 O 8 ‐ concentration in about 300 samples, exceed but in few hydromorphous and subhydric materials 5 ppm, not so in A‐horizons of marsh soils and samples taken from deposits of the small streams and creeks to and from the Eifel‐maar's. Elevated U 3 O 8 ‐concentrations observed in maar gyttja could be due to volcanic discharge into the maar. In uranium bearing crystallin regions (regions Mähring, Böhmerwald; Weißenstadt, Fichtelgebirge; Ellweiler, Nahesenke; Menzenschwand and Wittichen near Alpirsbach, Black Forest) all measurement indicated strongly elevated U 3 O 8 ‐ concentrations, especially in creek deposits and gley soil, but not so in A and B horizons of terrestric soils (dystrophic cambisols) even in the core of the uranium bearing region. Thus, U 3 O 8 analysis in creek deposits and gleys can render assistance in uranium prospections. U 3 O 8 measurements in soil fractions are highest in the acid treated fractions ‘fulvic acid’ and ‘residue after humine precipitation’. Uranium contents relative to sample ‐ C are highest in the whole soil and extraction residue of the soil, pointing either to stronger link with the mineral part of the soil or to desorption of the uranium from the humic matter fractions in course of the alkali extraction.
