sample_remark Roberts et al 2006 paraphrased "Pale-red, unwelded, ignimbrite containing scattered (5 - 10%), fine to coarse phenocrysts (up to 2.5 mm in length) of plagioclase, opaque minerals and, at one locality each, minor hornblende and quartz. Pumice fragments have flow-foliated and vesicle-rich textures. Volcanic rock fragments rare. Shards undeformed, frequently broken, commonly triaxons and randomly to moderately well oriented; vesicles common and slightly deformed. Groundmass normally a chlorite - zeolite mosaic."
