Paraschoepite occurs as an alteration product of schoepite in the oxidised zone of uranium-bearing mineral deposits (HOM).

Localities

At the type locality, the Shinkolobwe mine, Shinkolobwe, Kambove District, Haut-Katanga, DR Congo, crystals of paraschoepite to several millimetres have been found directly on pitchblende or with secondary uranium minerals; they are very closely associated with becquerelite and are frequently found as deposits on that mineral. Other associates include schoepite and uraninite (AM 32.344-348, HOM).

At the Cherkasar U Deposit, Pap, Chatkal-Kuraminskii Range, Namangan Region, Uzbekistan, paraschoepite is associated with schoepite, arsenuranylite, metazeunerite, uranospinite and nováčekite (HOM).
