| Large pillow. 5-10% vesicles, with spherical ~1 mm across vesicles evenly distributed throughout the rock and some larger generally elongate vesicles up to 5 x 2 mm. 10-15% plagioclase phenocrysts both discrete and in clusters up to ~3 mm across, with rare crystals to 5 mm across. One plagioclase megacryst >1 cm across. Sparse dark green clinopyroxene phenocrysts appears light green where fractured, and occurs as rounded 1-2 mm across crystals. Lava exfoliated when hammered, leaving a solid ~20 cm diameter core. Exterior covered with red/brown FeMnOx and palagonite. All glass appears devitrified. | ||
