4-8-026: diabase - Mineral Creek District - Ray Mine

Details

Specimen Number4-8-026Alternate NumberR-6CommentsDiabase, from same zone as sample R-5 (4-8-025). Sample is cut by veinlets of coarse pyrite and quartz with selvages which show variation in degree of silicification and sericitization. The watery gray material adjacent to veins is strongly silicified/sericitized diabase. Relict diabase can still be seen away from veinlets in cores of now altered diabase. Minor chalcopyrite and pyrite, non-ore material in general.In Teaching CollectionNoMineral(s)pyritepyroxenequartzsericiteRock NamediabaseDistrictMineral CreekMineRayExternal LinkMindatGeo-LocationundefinedSub-LocationundefinedDeposit TypePorphyry CopperGeo-Coords^[1]Reference MaterialACL-115: Hoelscher, S.A., 1977, Structural Geology of the Ray mine, Recent Developments, AZ Conference AIME, Mining Geology Division Meeting, Ray Mine, AZ, April 16, 1977, 18 p.
