Sedimentary facies and physical properties of the latest Pleistocene to Holocene sediment core GS-TKT-1 in the Arakawa Lowland, Toda City, Saitama Prefecture, central Japan

Fluvial response to sea-level changes since the latest Pleistocene in the near-coastal lowland, central Kanto Plain, Japan

“…The profiles downstream from the lower Arakawa Lowland in Fig. 5 are from previous studies (Matsuda, 1974(Matsuda, , 1993Kaizuka et al, 1977;Ando et al, 1987;Ando and Fujimoto, 1990;Ando and Watanabe, 1996;Ando and Houtigai, 1997;Komatsubara et al, 2009). Along the profile in the upper Arakawa Lowland and middle Arakawa Lowland, the average gradients of surfaces II and III are 0.85/1000 and 0.92/1000, respectively.…”

“…The timing of this change of sedimentary environment corresponds to the onset of delta progradation between 7.5 and 7.0 ka in the lower Arakawa Lowland (Komatsubara et al, 2009). Sea level had stabilized by ca.…”
