Zincolivenite
The zinc-bearing member of the olivenite group — green-blue copper-zinc arsenate crusts.
Intro adapted from Wikipedia (CC BY-SA).
Zincolivenite is an IMA-recognized mineral species in the arsenate class, with the chemical formula CuZn(AsO₄)(OH).
It crystallizes in the orthorhombic crystal system (space group Pnnm). It is a member of the Andalusite structural group.
Key properties: Mohs hardness 3.5; specific gravity 4.34; White streak; Vitreous luster; refractive index 1.888; optically biaxial.
IMA symbol Zoli, IMA status: approved, named in 2006.
Secondary in weathered tennantite deposits.
It is found associated with Jarosite, conichalcite, alumopharmacosiderite, arseniosiderite, scorodite, ‘limonite’ (Lavrion); azurite, tyrolite (Dolyhir quarry); philipsburgite.
The prefix identifies the zinc-dominant analogue of olivenite. Formerly ‘cuproadamite’.
