1R-1 (1) 1 0.00 0.06 0.06 Fresh, moderately vesicular, sparsely plagioclase-phyric dacite. Plagioclase, clinopyroxene, and rare magnetite phenocrysts (1-3 vol%) are generally <1 mm (maximum dimension). Unaltered to slightly altered. Alteration includes: incipient groundmass bleaching, silica hairline veins, silica ± clay ± sulfate films, Fe oxide films, zeolite crystals in vesicles, and Fe oxide spots with calcium carbonate.
