Text Description:
Block from brecciated material at Site 12. Fine grained, vesicular, holocrystalline, seriate porphyritic with a matrix of mesostasis, opaque, microlites, plagioclase, and olivine. Plagioclase phenocrysts (An28-An61) are up to 7 mm, most <1.8 mm, and some display sieve textured cores and normal or oscillatory zoning. Olivine phenocrysts are up to 1.5 mm and a few display resorption embayments or opaque inclusions. Orthopyroxene phenocrysts are up to 0.5 mm.
