Nadorite occurs as an alteration product of other antimony-bearing minerals in hydrothermal mineral deposits, associated with jamesonite, galena, sphalerite, bindheimite, senarmontite, valentinite, anglesite, cerussite, smithsonite and mimetite (HOM, Mindat).

Localities

At the type locality, the Nador n'Bails mine, Djebel Nador, Guelma District, Guelma Province, Algeria, nadorite is associated with smithsonite, bindheimite and anglesite (Mindat, Dana).
