Notes. The values r10v, r50v and r90v represent the 10th, 50th, and 90th percentiles of the cumulative volume-based grain size distribution of the respective materials. The last column is a measure for the width of the size distribution. (1) Güttler et al. (2009); (2) Meisner et al. (2012); (3) Machii et al. (2013); (4) Schräpler et al.
