Dec 07, 2005 (D Laidlaw) - The occurrence was described by Spence (1940) as soft, yellowish to pale brown renesselaerite-steatite derived from altered pyroxenite. The dolomite which hosts the pyroxenite is in part serpentinized. The rock has a coarse, irregular grain, as the original form of the pyroxene crystals was preserved. The talc unit was examined in thin section by LeBaron and van Haaften (1989) and found to be pyroxene crystals replaced by 80 percent talc and 10 percent carbonate. In the quartz-free zones, the rock was reported by Spence (1940) to cut easily. The majority of material however contains a mixture of quartz, dolomite and serpentine.
