Pyrite
iron(II) disulfide mineral / From Wikipedia, the free encyclopedia
The mineral pyrite,[1] or iron pyrite, is an iron sulfide with the formula FeS2. This mineral's metallic lustre and pale-to-normal, brass-yellow colour have earned it the nickname fool's gold because of its resemblance to gold.[2][3][4][5][6][7] The term pyrite may also be used for some other sulphides such as copper sulphide.
