An interesting mineral assemblage consisting of uraninite, anilite, covellite, clausthalite, chalcopyrite, tetrahedrite and naumannite? accompanied with wulfenite and supergene uranium minerals was identified using electron microprobe and XRD in material collected in dumps of the small abandoned uranium occurrence at Dlažov, western of Klatovy, SW Bohemia (Czech Republic). Uranium mineralization is bound to quartz-carbonate hydrothermal veins penetrating mostly contact metamorphosed sediments of Proterozoic age adjacent to the Klatovy granodiorite. Sulphides and selenides forms a tiny unequal veinlets in quartz gangue accompanied by uraninite. Supergene uranium minerals comprise meta/autunite, meta/torbernite, uranophane, and β-uranophane.
