Campylite

Campylite is a variety of the lead arsenate mineral Mimetite. It received its name from the Greek ‘kampylos’ meaning bent, on account of the barrel-shaped bend of its crystals. It occurs in the upper lead deposits through the oxidation of galena or cerussite. The main deposits are Pribam in Bohemia, Czech Republic, and Dry Gill, Caldbeck Fells, near Wigton, Cumbria, UK.
