Qinglong Mine, Qinglong, Qianxi'nan Autonomous Prefecture, Guizhou, Southwest Region, China.
Cyanotrichite is a secondary mineral of the oxidation zone of copper deposits. Its genesis seems facilitated by an acid environment and a clayey surrounding. It owes its name to the Greek kuanos (blue) and thrix (hair) in connection with its color and its habitus in tufts of acicular crystals. It comes in orthorhombic fibers assembled in radiate rosettes, urchins with velvety aspect and silky luster. Its sky blue to azure blue color and its pale blue streak are characteristic as well as its association with other arsenates and sulphates of copper (chalcophyllite, spangolite, brochandite, adamite, etc...). It is a mineral little known to collectors who has no particular use.
