Stannoidite
Stannoidite is a sulfide mineral composed of five chemical elements: copper, iron, zinc, tin and sulfur. Its name originates from Latin stannum and Greek eides. The mineral is found in hydrothermal Cu-Sn deposits.
Stannoidite was first described in 1969 for an occurrence in the Konjo mine, Okayama prefecture, Honshu Island, Japan.
