Geosphere, October 2010, v. 6, p. 524-536, doi:10.1130/GES00537.1, Supplemental Figure 4 - PDF file image of volcanic diamictite predominantly composed of granuleto small pebble-sized (up to 4 cm in diameter) clasts of pumice, scoria, and lava immersed in sand-sized matrix. The volcanic clasts are subangular to angular; red vesicular scoria are abundant. Beds are faintly stratified horizontally by changes in clast content and dominant clast types at decimetric scale. The matrix of this breccia is mainly composed of pumice sand that typically forms >50% of the matrix but locally exceeds 90%. The matrix also includes zeolites and calcite.
