Anhydrous arsenate containing hydroxyl, tarbuttite group, triclinic paramorph of orthorhombic adamite, zinc-bearing mineral
Specific gravity: 4.55
Colour: Pale yellow
Paradamite is a rare secondary mineral in the oxidised
zone of some hydrothermal polymetallic base-metal deposits
At the type locality, the Ojuela Mine, Mapimí, Mapimí Municipality, Durango, Mexico, paradamite was found as a secondary mineral in the oxidised zone of the silver-lead-zinc mine (Webmin ). It occurred as sheaflike aggregates of crystals and as equant crystals up to 5 mm in size. The paradamite was associated with mimetite and adamite on a matrix of limonite. Legrandite, plattnerite and murdochite occur at the same locality (AM 41.958). Other associated minerals include ojuelaite and mapimite (HOM).
At the Tsumeb Mine, Tsumeb, Oshikoto Region, Namibia, paradamite is associated with köttigite, adamite, smithsonite, wulfenite and chalcocite (HOM).
