mineral and ore clasification

Ore clasts may be replaced by chalcopyrite and in rare cases by bornite associated with enrichment of the upper part of the layers in gold Sulphide sandstones are well preserved mineralogically as pyritic ore clasts at the base of turbiditic units commonly retain primary sphalerite framboidal and colloform pyrite …
