Chenevixite
Chenevixite is an IMA-recognized mineral species in the arsenate class, with the chemical formula CuFe³⁺(AsO₄)(OH)₂.
It crystallizes in the monoclinic crystal system (space group B2_1). It is a member of the Chenevixite structural group.
Key properties: Mohs hardness 3.5–4.5; specific gravity 4.38; Greenish yellow streak; optically biaxial.
IMA symbol Cvx, grandfathered status — known before the IMA’s founding, named in 1866.
Occurs as an uncommon secondary mineral in the oxidized zone of some hydrothermal polymetallic mineral deposits.
It is found associated with Quartz (Cornwall, England); olivenite, quartz (Tintic district, Utah, USA); olivenite, scorodite (Majuba Hill, Nevada, USA); malachite, bystromite.
The mineral was named to honor Richard Chenevix (1774–1830), Irish chemist, who early analyzed a Cornish Cu–Fe arsenate.
