Vesicular pillows (15-20% vesicles, <2 mm across, spherical) with some thin but fresh glass. Mildly phyric with 5% plagioclase phenocrysts and ~1% olivine phenocrysts, both 2-3 mm across and occurring separately or as clusters.
As for 43-01.
Light grey lava, more finely vesicular with smaller (~1 mm) phenocrysts of plagioclase and olivine. Altered green-grey to reddish exterior and to a lesser degree throughout.
