Pyrite | Common Minerals
In calcite and quartz veins, pyrite is commonly associated with chalcopyrite and other sulfide minerals and metallic ores. Pyrite oxidizes to other iron sulfate minerals that in turn alter to limonite, so the presence of a weathered 'rusty' limonite layer may indicate the presence of pyrite in the underlying rock.
