GRD028ZT0: Serpentine with occasional clusters of pyroxene and subhedral opaque minerals as well as white and yellow veins. The thin section has both the highly-fractured center ot the sample and the less-fractured portion of the sample. Small fractures/veins seem to be radiating out from the center (see thin section slide scan.) (Thin section is with the sample.) (C. Eichler)
