Laurionite

Laurionite (PbCl(OH)) is a lead halide mineral.

It forms colorless to white crystals in the orthorhombic crystal system and is dimorphous with paralaurionite, both members of the matlockite group.

[2] It occurs as an oxidation product in lead ore deposits, and is also produced on lead-bearing slag by reaction with saline solutions.

It occurs associated with paralaurionite, penfieldite, fiedlerite, phosgenite, cerussite and anglesite.
