Text Description:
Blocky outcrop that may be a remnant of a blocky flow. Overlies bomb lahar unit 94SJP113C. Fine grained, vesicular, holocrystalline, porphyritic with a matrix of mesostasis, plagioclase, and opaque. Plagioclase phenocrysts (An36-AN59) are up to 1.0 mm. Olivine phenocrysts are up to 0.75 mm and the grains are altered and have black coronas. Clinopyroxene phenocrysts are up to 0.5 mm and are often rounded. One orthopyroxene phenocryst, 0.1 mm, was observed.
