Becquerelite occurs as a weathering product of uraninite in oxidised portions of uranium deposits, and, more rarely, in pegmatites (HOM).

Localities

At the type locality, the Shinkolobwe mine, Shinkolobwe, Kambove District, Haut-Katanga, DR Congo, becquerelite occurs among weathering products of uraninite in the oxidised portions of a uranium deposit, associated with uraninite, schoepite, soddyite, curite, fourmarierite, dewindtite, ianthinite, wölsendorfite, rutherfordine, masuyite and kasolite (HOM), Mindat.

At the Wölsendorf fluorite mining district, Upper Palatinate, Bavaria, Germany, becquerelite occurs in a fluorite deposit with schoepite and uraninite (Dana).

At the Happy Jack Mine, White Canyon, San Juan county, Utah, USA, becquerelite is associated with johannite, uranopilite and zippeite (HOM).
