sample_remark Roberts et al 2006 paraphrased "Brown welded ignimbrite with medium to coarse (<0.5 - 2 mm, rarely 4 mm) phenocrysts (25 - 30%) of plagioclase, sanidine, quartz, an altered Fe/Mg mineral and opaque minerals. Pumice fragments large, lensoidal, coarsely recrystallised or spherulitic. Rock fragments (up to 14 mm) mainly fine devitrified ignimbrites. Shards thick, flattened, strongly aligned. Vesicles almost flat. Groundmass chloritic to partially micropoikilitic."
