Text Description:
Basaltic hyaloclastite lava flow. Augite, olivine, and hornblende phenocrysts in a slightly vesicular groundmass of plagioclase microlites, olivine, augite, and dark brown devitrified glass. Olivine phenocrysts occur as both large euhedral and small skeletal crystals. Augite commonly occurs in rounded clots of augite +/- olivine. Plagioclase is absent as a phenocryst but several rounded, sieve textures crystals are present as xenocrysts.
