Geosphere, October 2010, v. 6, p. 524-536, doi:10.1130/GES00537.1, Supplemental Figure 2 - PDF file image of pumiceous lapilli tuff to tuff. Deposits are moderately well sorted and are composed of clasts ranging from coarse ash to lapilli (~1 cm). Lapilli tuff are clast supported. Although sorting and bedding are partially obscured by alteration, faint normal grading occurs. Few coarse sand-sized grains of red scoria occur in the interval. Clasts are often cemented by calcite. Patches and lenses of pyrite occur.
