Figure F70. Photomicrographs showing phenocrysts. A. Fresh olivine phenocrysts in fresh glassy margin (Sample 206-1256D-14R-2, 84-96 cm; width of view = 0.7 mm). B. Pseudomorph of a skeletal large olivine phenocryst in a cluster with plagioclase laths, which enclose smaller equant olivine (Sample 206-1256D-46R-1, 24-28 cm; width of view = 1.4 mm).
