Metallic Oxides
A mineral composed of the hydroxide carbonate of zinc and copper (Zn, Cu)5(OH)6(CO3)2. It is commonly found with malachite in the oxidized zone of zinc and copper deposits as at Tomsk, Siberia; Santander, Spain; and Bisbee, Ariz., U.S. Its pale blue-green featherlike form distinguishes it from malachite; and, because it is a weathered product of zinc-rich ores, it can serve as a guide to zinc deposits.
