Cupalite

Native element class, alloy

Cupalite is a rare mineral which is mostly composed of copper and aluminium , but might contain up to several percent of zinc its chemical structure is therefore described by an approximate formula (Cu,Zn)Al or (Cu,Fe)Al. It was discovered in 1985 in placers derived from serpentine, in association with another rare mineral khatyrkite (CuAl2). Both minerals are thus far restricted to the area of Listvenitovyi Stream, in the Khatyrka (silicon -poor) zone of the Koryak–Kamchatka fold area, Koryak Mountains , Chukotka Autonomous Okrug , Far Eastern Federal District The mineral name derives from cuprum (Latin for copper) and aluminium. Its holotype (defining sample) is preserved in the Mining Museum, and parts of it can be found in other museums, such as Museo di Storia Naturale di Firenze
