instumentite

Instrumentite is a mineral species that was first discovered in 1997. It is a rare, secondary mineral that forms in the oxidation zone of copper deposits. The mineral is typically found in association with other secondary copper minerals such as malachite, azurite, and chrysocolla. Instrumentite is named for its unique, instrument-like appearance, which is characterized by its elongated, prismatic crystals that often form in clusters or radiating groups.

The chemical composition of instrumentite is complex, with the ideal formula being (Cu,Zn)2(OH)3Cl. The mineral is typically a bright blue to blue-green color, although it can also occur in shades of green, yellow, or brown. Its hardness on the Mohs scale is approximately 3.5, and it has a specific gravity of around 3.5. Instrumentite is translucent to transparent, with a vitreous to pearly luster.

Instrumentite is of limited economic importance, as it is not typically mined for its own sake. However, it is sometimes collected by mineral enthusiasts due to its unique appearance and rarity. The mineral is also of interest to scientists studying the processes of mineral formation and weathering in copper deposits.
