Galena: PbS or (Pb,Ag,As,Sb,Cu)S.

Is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantite-tetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces. The crystals are bright when fresh but often tarnish after exposure to air and especially when people touch it. Lead sulfide may contain impurities, such as silver, arsenic, antimony, and copper.

Chalcopyrite: CuFeS2.

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.
