Figure F58. Close-up photograph showing orthopyroxene-bearing serpentinized dunite band sandwiched by harzburgite. The boundaries of the band are defined by the appearance of abundant pyroxene along contacts that are parallel or subparallel to the crystal-plastic foliation defined by the shape of the pyroxene within the harzburgite. Light gray areas in the dunite are talc altered, and buff brown bands are serpentine-altered fine-grained cataclastic regions (interval 209-1268A-6R-1, 46
