Chloroxiphite
Chloroxiphite is a rare olive green to pistacio green lead copper halide mineral with formula: Pb3CuO2Cl22.
It was first discovered in 1923 in the Mendip Hills, Somerset, England associated with mendipite. Like mendipite it is an oxychloride mineral and formed from the alteration of lead ore by secondary oxidation. In addition to mendipite, it occurs with diaboleite, parkinsonite, wulfenite, cerussite and hydrocerussite. Its name comes from the Greek words "green", describing its color, and "blade" as its crystal form is long blade-like crystals that often show the growth pattern and time taken to form.
