Cupropavonite from Pioche, NV, USA – micromount as unique piece
This micromount specimen shows Cupropavonite from Pioche, Nevada, USA. The piece is set in a light colored quartz rich matrix with finely distributed metallic areas. The surface appears irregular and shows typical intergrowth features of this rare sulfosalt mineral.
The mineralization occurs in a compact form and is mostly embedded in the matrix. Distinct crystals are not developed, instead a fine grained metallic shimmering distribution is visible, giving the specimen an interesting visual appearance.
Geology & Origin
Cupropavonite belongs to the group of sulfosalts and forms in hydrothermal vein systems, commonly associated with lead, silver and copper bearing mineralization. Its formation takes place under low to moderate temperature conditions in complex geochemical environments.
The Pioche mining district in Nevada is well known for its diverse sulfide and sulfosalt assemblages. It is considered a classic locality for rare ore minerals and continues to produce interesting specimens for specialized collectors.
