Vandenbrandeite is a rare secondary mineral in the oxide zone of hydrothermal copper-bearing uranium deposits (HOM).

Localities

At the Shinkolobwe Mine, Shinkolobwe, Kambove District, Haut-Katanga, DR Congo, vandenbrandeite is associated with curite, uranophane and sharpite (HOM).

At the Luiswishi Mine, Lubumbashi, Haut-Katanga, DR Congo, vandenbrandeite occurs as doubly terminated crystals to 1 cm in length (Dana).

At the type locality, the Kalongwe deposit, Kolwezi mining district, Lualaba, DR Congo, vandenbrandeite is associated with cuprosklodowskite, kasolite, sklodowskite, malachite, chalcocite, chalcopyrite, uraninite, goethite, uranophane and torbernite (Dana, HOM).

At Rabejac Est, Le Puech, Lodève, Hérault, Occitanie, France, vandenbrandeite occurs on pitchblende associated with chalcopyrite, chalcocite, kasolite, sklodowskite and malachite. It is an alteration product of pitchblende and chalcopyrite. (AM 18.179-180).
