Chalcopyrite: Mineral information, data and localities.

Chalcopyrite-Eskebornite Series. A major ore of copper. Common in sulfide veins and disseminated in igneous rocks. Weathering may lead to the formation of malachite, azurite, brochantite, langite and numerous other secondary copper minerals. A Zn-rich variety is known from Atlantis II Deep see zincian chalcopyrite .

Chalcopyrite - Wikipedia

Chalcopyrite is an accessory mineral in Kambalda type komatiitic nickel ore deposits, formed from an immiscible sulfide liquid in sulfide-saturated ultramafic lavas. In this environment chalcopyrite is formed by a sulfide liquid stripping copper from an immiscible sili e liquid.
