Kolwezite
Kolwezite is a rare copper-cobalt hydroxyl carbonate with the formula CuCo(CO3)(OH)2, chemically and structurally related to rosasite and glaukosphaerite within the rosasite group. First described in 1980, it takes its name from the town of Kolwezi in the Katanga Copper Crescent of the Democratic Republic of Congo, where it was discovered at the now-legendary Musonoi Mine, still recognized today as its type locality. As a member of the oxidized zone assemblage typical of copper-cobalt hydrothermal ore deposits, kolwezite forms through the alteration of primary sulfides in a supergene environment rich in both copper and cobalt, a geochemical combination found in very few places on Earth.
