Specimen Number9-4-032Alternate Number83-33CommentsAn oddity in the vicinity of the mine is the presence of some gilsonite-type veins that contain low-grade hydrocarbons that were likely "cooked" out of the host sediments. These are samples of this material. Some thin section work would help, almost looks like a calc-silicate.In Teaching CollectionNoMineral(s)clayRock NamegilsoniteDistrictBritish ColumbiaMineIsland CopperExternal LinkMindatDeposit TypePorphyry CopperGeo-Coords[1] Reference MaterialACL-6: Fleming, J., Walker, R., and Wilton, P., 1983, Mineral Deposits of Vancouver Island: Westmin Resources (Au-Ag-Cu-Pb-Zn), Island Copper (Cu-Au-Mo), Argonaut (Fe), Field Trip Guidebook #9, May 13-16, 1983, Joint Annual Meeting GAC-MAC-CGU, Victoria, British Columbia, 41 p.
