Comments on the geologic information

  • Geologic Description = Network of low grade cross-and slip-fiber chrysotile veinlets 0.5-2.0 in. (1-4 cm) wide in area of serpentine float 800 ft. (244 m) long, several hundred feet (60 m) wide and up to 8 ft. (2.5 m) deep. Nearby magnesite veinlets and asbestos as well as residual boulders of nephrite occurr over a wide area of serpentinized ultramafic rocks cutting schist (Heide and others, 1949, p.16-18).
