 Text Description:
Three to four foot diameter block/bomb on Tanada Cinder Cone at Site 15. Fine grained, vesicular, holocrystalline, seriate porphyritic with a matrix of mesostasis, opaque, plagioclase, olivine and pyroxene?. Plagioclase phenocrysts (An55) are up to 0.75 mm; most are small laths. Olivine phenocrysts are up to 0.75 mm, and occasionally have skeletal habits. May be some orthopyroxene? present. Mode: 78.2% matrix, 0.2% plagioclase, 1.3% olivine, 20.3% vesicles.
