Localities
At the type locality, the Shinkolobwe mine, Shinkolobwe, Kambove District, Haut-Katanga, DR Congo, bijvoetite
and lepersonnite-(Gd) occur with hydrated uranium oxides near
primary uraninite in
the lower part of the oxidation zone. Bijvoetite is rare and is known only from a single specimen here.
Associated minerals include lepersonnite-(Gd),
sklodowskite, curite,
uranophane, becquerelite,
rutherfordine, studtite
torbernite, soddyite,
kasolite, schoepite and
oursinite.
Bijvoetite is present as minute tabular yellow crystals
(AM 68.1248, HOM).
