Histograms of sizes of the partitioned phases: solid (s) and void (v). In the upper row, the relative frequencies (relative number of occurrences, ℘_gn and ℘_pn) as functions of cube root of grain and pore volumes (\({V}_{\mathrm{g}}^{1/3}\) and \({V}_{\mathrm{p}}^{1/3}\)) are shown. A few very voluminous outliers are omitted to improve resolution. In the lower row, there are the volume fractions (℘_gv and ℘_pv) as functions of the characteristic radii of grains and pores (R_g and R_p shown in the full range)
