Stratigraphic cross-section and sequence-stratigraphic classification of the upper Umegase Formation. Modified from Ito (1998). The oxygen isotopic data are from Pickering et al. (1999) and are adjusted to the stratigraphic section 6. The inset map shows the locations of the measured sections and the distribution of the submarine-fan system. U8–Ku5 denotes the coding of tephra key beds. SB11 is a sequence boundary defined by Ito and Katsura (1992). See Fig. S1 for the stratigraphic position of SB11 within the Kazusa Group
