Text Description:
Fine-grained to very fine-grained, dark-gray (N 3), porphyritic andesite (S; high-silica andesite G) containing common very light-gray (N 8) phenocrysts of plagioclase. Major minerals are plagioclase (An 65), clinopyroxene, and sparse orthopyroxene. Pilotaxic groundmass contains weakly flow foliated plagioclase laths and glass.
