Details

Specimen Number4-8-019Alternate NumberP-9CommentsMetaargillite or metaarkose. From what mine geologists referred to as the gray-green zone. Appears to be an argillized sediment with banding reflecting variable quartz content within joint and fracture sets that are not bedding parallel. Alteration phases include quartz, K-spar, minor sericite, kaolinite, and montmorillonite. Grade from 0 to 0.05% Cu with trace Mo to 0.01%. This material is from an irregular zone within the hanging wall clastics that is disconformable with respect to bedding, and is related to the upper and outer contact of the quartz monzonite porphyry dikes.In Teaching CollectionNoMineral(s)chalcopyritepyritequartzsericiteRock NamemetaarkoseDistrictPimaMinePimaExternal LinkMindatGeo-LocationundefinedSub-LocationundefinedDeposit TypePorphyry CopperGeo-Coords^[1]Reference MaterialACL-109: Thurmond, R.E., and Storms, W.R., 1958, Discovery and Development of the Pima Copper Deposit, Pima Mining Co., Pima County, Arizona, Bur.
