a K2O vs. SiO2 contents on an Na2O-free basis. This figure shows mass balance among the bulk rock composition of the sieved FOB 2021 floating pumice (open circles), averaged composition of groundmass glass (cross), and averaged composition of whole crystals (square). Solid circles represent bulk rock composition of the gray pumices from Yoshida et al. (2022b). b K2O content on an Na2O free basis vs. particle size of sieved floating pumice. Shaded range represent bulk rock composition of the gray pumices from Yoshida et al. (2022b)
