malachite (redirected from Green carbonate of copper)

malachite (măl`əkīt), a mineral, the green basic carbonate of copper occurring in crystals of the monoclinic system or (more usually) in masses. It is translucent or opaque; the luster is silky, vitreous, adamantine, or dull. It takes a good polish. An important ore of copper, it also serves as a gem and for various ornamental purposes and, when finely ground, as a pigment. It is found associated with other ores of copper (especially azurite) in various parts of the United States and in Chile, Russia, Congo (Kinshasa), Zimbabwe, and Australia.

malachite

Widespread carbonate mineral of copper, a hydrous copper carbonate, Cu₂CO₃(OH)₂. Because of its distinctive, bright green colour and its presence in the weathered zone of nearly all copper deposits, malachite serves as a prospecting guide. It is found in Siberia, France, Namibia, and Arizona. Malachite has been used as an ornamental stone and as a gemstone.
