Stratigraphy
| Geological group: | Osaka | Formation: | Shoudai | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: "The leaf fossil assemblage was in fluvial silt 2.5 m below the Kasuri tephra bed, dated to 0.42 ± 0.08 Ma by the FT method (Suzuki, 1988). The Ma 8 marine clay bed situated just at or several meters above the Kasuri tephra bed in this area (Mitamura, 1992) was correlated with MIS 13 (Yoshikawa & Mitamura, 1999), which was astronom- ically tuned to ca. 0.5 Ma (Lisiecki & Raymo, 2007)."
