Deposits of copper bearing pyrite are widely distributed and often of great size. They usually occur in or near the contact of eruptive rocks with schists or slates. Pyrite weathers rapidly to hydrated iron oxide, goethite, or limonitedomorphs of goethite after pyritemon. This weathering produces a characteristic yellow brown stain or coating, such as on rusty quartz
