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).
