Linarite xls; Tsumeb Mine, Otavi Mountains, Namibia; TN; unique piece
Light green Linarite crystals from the Tsumeb Mine, Otavi Mountains, Namibia – micromount as unique piece
This micromount specimen from before 1986 shows lime green Linarite crystals from the Tsumeb Mine in Namibia. The piece stands out due to its vivid coloration and the typical appearance of this rare secondary copper mineral.
The Linarite crystals display intense blue green to lime green tones contrasting strongly with the darker matrix. The crystals are finely developed and form an irregularly structured matte surface. Despite the rather massive appearance the crystalline character is clearly recognizable giving the specimen a visually striking and colorful presence.
Geology & Origin
Linarite is a secondary lead copper sulfate hydroxide mineral forming in the oxidation zone of lead and copper deposits. It develops through complex weathering processes and is especially known for its intense blue to blue green coloration.
The Tsumeb Mine in the Otavi Mountains is one of the most important mineral localities in the world. Its exceptional geochemical conditions have produced a wide variety of secondary minerals including rare and vividly colored Linarite specimens.
