    Chalcopyrite: Mineral information, data and localities.

    Chalcopyrite Group. 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).Also, the Mid-Atlantic-ridge

    University of Minnesota’s Mineral Pages: Chalcopyrite

    Some Spanish chalcopyrite and pyrite bodies have been continuously mined for over three thousand years to produce copper and sulfur, along with other associated minerals such as gold. More recently, copper’s high conductivity, softness, and resistance to corrosion, have given it a critical role in generating and distributing electrical power.
