Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite. Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits. Bornite is also found as disseminations in mafic igneous rocks, in contact...

Bornite occurs globally with the usual copper ore deposits. 126.96.36.199 Chalcocite. Chalcocite is a black lead-gray color copper sulfide (Cu 2 S) mineral with shiny black streak. The harness and specific gravity vary between 2.53.0 on the Mohs scale and 5.55.8, respectively. Chalcocite is a characteristic mineral formed by weathering and
Chalcocite (UK: /ˈkælkəˌsaɪt/), copper(I) sulfide (Cu2S), is an important copper ore mineral. It is opaque and dark-gray to black with a metallic luster. It has a hardness of 2 1⁄2 3 on the Mohs scale. It is a sulfide with an orthorhombic crystal system. The term chalcocite comes from the alteration of the obsolete name chalcosine
Chalcocite forms from the alteration of other minerals, especially other copper sulfides such as Bornite, Covellite, and Chalcopyrite, and may also form pseudomorphs after these minerals.It often forms in association with Chrysocolla, with the Chrysocolla forming as an alteration around the Chalcocite.
Upon surface exposure, bornite will weather to chalcocite or other copper minerals. Bornite is a popular and fast-selling mineral specimen at museums, mineral shows, and tourist shops. However, some material sold as "peacock ore" has a tarnish with spectacular colors greatly exceeding what is expected on bornite.
