Oct 16, 2017 (A Wilson) - The outcrop at site RAM-02 is about 50 m X 12 m in area, with a blocky surface caused by deep weathering along joint planes. The rock is a white, fine to medium grained dolomite with minor amounts of hematite, mica, graphite, tremolite, pyrite, and calcite. The chemistry of samples 1804 from Papertzian and Kingston (1982) and 89 RAM-02, shown below,indicate the high purity of this dolomite. The width of the dolomite zone appears to be about 15 m, flanked by calcitic marble and diorite to the north and by impure dolomite containing greater than 5% tremolite and serpentine to the south.
