    SCARCE OLD REPORT
    This is USGS Bulletin 1513,
    Sapphirine in Precambrian Rocks Associated with Stratabound Sulfide Deposits, Custer County, Colorado
    . Published in 1980, this 22 page book discusses a new occurrence of sapphirine, a rare mineral known from few localities in the world. The occurrence in Custer county is unusual for its association with sulfide bodies in Precambrian rocks, not the usual associations. This short report comes with a location map and several photographs of the mineral and its associates in the microscope. The occurrences are at the a couple of the mines near San Isabel. The mines are:
    Marion mine
    Amethyst prospect
    Sapphirine was found on mine dumps and in rocks near the mine openings at one location. Details are given for both locations.
    This is a cool old report that may help you find examples of this rare mineral.
