 Text Description:
Flow cascading over 94SJP121B from the Tanada Cinder Cone at Site 15. Fine grained, vesicular, dikytaxitic, holocrystalline, trachytic, porphyritic with a matrix of mesostasis, opaque, plagioclase, olivine, and pyroxene?. Plagioclase phenocrysts (An47-An59) are up to 0.3 mm, and most are small laths, the largest grain is sieve textured. Olivine phenocrysts are up to 0.75 mm and occasionally have skeletal habits. May be orthopyroxene? present.
