Nadorite

Nadorite is a mineral with the chemical formula PbSbO2Cl. It crystallizes in the orthorhombic crystal system and is brown, brownish-yellow or yellow in colour, with a white or yellowish-white streak.

Nadorite is named after Djebel Nador in Algeria, where it was first identified in 1870. Djebel Nador and Djebel Debbar (both in the Constantine Province of Algeria) are its co-type localities.
