  • 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 isocubanite
