Native copper is widespread in the oxidized zone of copper deposits, but even in these deposits is a relatively minor ore mineral. Copper is also found associated with basalts, but the only place it was a major ore mineral was in the Keweenaw peninsula. Copper is also a major ore mineral as a cement in the sedimentary rocks at Corocoro. Mineral de cobre (Cu) minerales son compuestos naturales que contienen cobre en varias composiciones químicas.
