Stratigraphic variation of the fusion residues. a, c, e Mass fraction of the fusion residues for a MR14-E02 PC11, c KR13-02 PC05, and e IODP Site U1366 (Usui et al. 2018). b, d, f Stack plots showing mineral proportions in the fusion residues of b MR14-E02 PC11, e KR13-02 PC05, and e IODP Site U1366 (Usui et al. 2018). Ages are based on (1) Nozaki et al. (2019), (2) Usui and Yamazaki (2021), (3) Ohta et al. (2020), (4) Yamazaki et al. (2020), and (5) Dunlea et al. (2015a). Qz: Quartz, Pl: Plagioclase, Kfs: K-feldspar, Cpt: Clinoptilolite. The chemostratigraphic units (Tanaka et al. 2020a) are shown at the top of a, b, c, and d. For a color cord, see Fig. 1
