Details

Specimen Number5-3-011Alternate NumberSB-10CommentsSilverbell alaskite. Nicely developed supergene alteration. Pervasively phyllically altered characterized by sericite + quartz + pyrite. Also contains quartz + pyrite + chalcopyrite veinlets. Some relict K-spar. Most pyrite and chalcopyrite have thin coating of supergene chalcocite. It's interesting to note that the amount of chalcocite is quite minor but would look like more as most primary sulfides are thinly coated. Sample from the west end of the El Tiro pit on the 2470 bench, and would likely run 1% Cu.In Teaching CollectionNoMineral(s)chalcocitechalcopyritefeldsparquartzRock NamealaskiteDistrictSilver BellMineSilver BellExternal LinkMindatGeo-LocationWeat of El Tiro pit;2470 benchSub-LocationundefinedDeposit TypePorphyry CopperGeo-Coords^[1]Reference MaterialACL-127: Dilbert, C., and Davis, S., 1981, Trip #10 Silver Bell-North Silver Bell Deposits, in Wilkins, J., coord., AZ Geol.
