Descoizite thumbnail mineral, Namibia.
Descloizite is a rare lead-zinc vanadate mineral that is known for its distinctive and complex crystal formations. It is a secondary mineral, typically forming in the oxidized zones of lead-zinc deposits. Descloizite was first discovered in the early 19th century and was named after the French mineralogist Alfred Louis Olivier Descloizeaux.
Namibia is one of the notable locations where descloizite specimens are found. The Tsumeb Mine in Namibia is renowned for producing high-quality descloizite crystals. The mineral occurs in a variety of colors, including brown, red-brown, yellow-brown, and green-brown. Its crystals often exhibit tabular or prismatic habits and can form in dense clusters.
The Tsumeb Mine, located near the town of Tsumeb, has been a prolific source of descloizite specimens. These Namibian descloizite specimens are sought after by mineral collectors for their well-defined crystals and unique coloration. The green-brown descloizite from Namibia is particularly prized.
Descloizite is often associated with other secondary minerals like vanadinite, wulfenite, and mimetite. Its formation is linked to the oxidation of primary lead-zinc ore deposits in the presence of vanadium-bearing fluids.
Collectors appreciate Namibian descloizite specimens not only for their aesthetic appeal but also for their geological significance. The crystals are typically found in association with a variety of minerals, creating visually interesting specimens that showcase the complex mineralogical history of the Tsumeb Mine. Care should be taken when handling these specimens to avoid damage to the delicate crystal formations.
