Figure F71. Photomicrographs showing phenocryst clots (Sample 206-1256D-55R-2, 63-64 cm; width of view = 0.7 mm). A. Normally zoned plagioclase partially enclosing augite microphenocrysts. B. Reversely zoned plagioclase in a crystal clot with augite and olivine. Note that augite microphenocrysts are not in direct contact with riddled, resorbed core of plagioclase.
