- It occurs in oxidized hydrothermal tungsten-lead ore deposits typically in association with raspite, cerussite, anglesite, pyromorphite and mimetite.
- Secondary minerals consist of lead minerals like anglesite, cerussite, pyromorphite and wulfenite, and of iron sulfides like marcasite and pyrite.
- Next comes a 5 centimeter wide quartz band in boxwork facies, that is also very rich in the secondary minerals pyromorphite and crocoite.
