Schultenite is a rare secondary mineral in the oxidised zone of lead-arsenic hydrothermal deposits (HOM).
Associated minerals include anglesite, bayldonite,
cuprian adamite, keyite,
galena, quartz and
Schultenite alters to anglesite (Dana).
At North Bend, King county, Western Australia, schultenite has been found in vugs in a quartz - arsenopyrite vein with galena and mimetite, and associated with cuprian adamite, keyite and tennantite (Dana).
At the type locality, the Tsumeb Mine, Oshikoto Region, Namibia, schultenite has been found in the oxidised zones of lead deposits, on a matrix of bayldonite pseudomorphous after anglesite, azurite and mimetite (AM 12.296).
