Figure F29. Close-up photograph showing a small intrusion of gabbro into serpentinized harzburgite. The gabbro is represented by the rubbly, talc-altered material in the center of this section. The margins of the serpentinized harzburgite are overprinted by talc alteration. This observation suggests that at least some of the observed talc alteration is related to the presence of gabbro (interval 209-1268A-16R-2, 43
