Auricupride

Auricupride

Named for the gold and copper in the composition, which in Latin are aurum and cuprum, respectively. Auricupride is a rare mineral that can be found in localities in Russia, the island of Cyprus, Switzerland, Chile, and additional localities in Argentina, South Africa, Australia, the Czech Republic, and Greece. At its Russian localities, Auricupride occurs “in serpentinites as a product of low-temperature ordering and [separation] of Au-Cu solid solution alloys,” and at a Swiss locality it can be found in reduction halos in red beds.
