Fig. 2

Stratigraphic summary of the Pleistocene Shimosa Group and correlation with MISs. The stratigraphic framework and depositional age summarised in Nakazawa and Tanabe (2011) are shown in the left column. Among the widespread tephra beds in the Shimosa Group, those detected in core GS-UR-1 (J4, Km2, Km4, and Hk-TP) are shown in bold (Nakazawa and Nakaszto 2005). The Yokota and Kiyokawa formations shown in shaded boxes are lacking due to the erosion during MIS 6 at the core site of GS-UR-1 (Nakazawa and Nakaszto 2005). The marine oxygen isotope curve is adapted from Lisiecki and Raymo (2005)
