Lithological logs of the Yoro River and Yoro-Tabuchi sections. The horizons of the samples for geochemical analyses (CN analysis, and XRF analysis) are highlighted. Logs are modified from Suganuma et al. (2018). The Lower-Middle Pleistocene boundary corresponds with the base of the Byk-E tephra (at 0 m in the lithological logs)
