Damaraite
Damaraite is an IMA-recognized mineral species in the halide class, with the chemical formula Pb₃O₂(OH)Cl.
It crystallizes in the orthorhombic crystal system (space group Pmc2_1).
Key properties: Mohs hardness 3; specific gravity 7.84; White streak; Adamantine luster.
IMA symbol Dm, IMA status: approved, named in 1989.
From a late-stage vein cutting a banded manganese ore lens in Cu–Pb–Ag ores formed by hydrothermal and metasomatic replacement of dolostones (Kombat mine, Namibia).
It is found associated with Jacobsite, hausmannite, hematophanite, defernite, crednerite, asisite, andradite, vesuvianite, copper, calcite, barite (Kombat mine, Namibia).
The name refers to the Damara dolostone sequence, which hosts the Kombat deposit.
