Marine and fluvial terraces in the Kanto Plain mostly formed in marine oxygen isotope stage (MIS) 5 under the concurrent influence of eustatic sea-level changes and Kanto basin-forming movements. In the central part of the plain, however, it remains unknown when and how terraces composed of the upper Pleistocene Joso and Kioroshi Formations, Shimosa Group developed. Terrace surfaces are classified by integrating geomorphic, sedimentary facies, and tephra analyses focusing on the southern Sashima and Tsukuba Uplands, including the northwestern Shimosa Upland. Terrace surfaces are classified into levels I to III . Terrace sediments distributed over levels I to II from the top in the Sashima, Tsukuba, and Shimosa Uplands are divided into two formations: Kioroshi Formation composed of beach facies and Joso Formation composed of flood plain and fluvial channel facies.Found in the Joso Formation were tuffaceous silt layer and pumiceous sand layer, including tephra grain correlated with On-Pm1 (c. 96 ka: Aoki et al., 2008) and Nk-Ma (c. 100 ka: Yamamoto, 2012) in the southern Sashima and Tsukuba Uplands, which allow fluvial terraces formed in the Central Kanto Plain after MIS 5c to be identified. * 東京大学大学院新領域創成科学研究科自然環境学専攻 ** 千葉県立中央博物館地学研究科 *** 農業・食品産業技術総合研究機構農村工学研究部門 **** 産業技術総合研究所地質情報研究部門 + 現所属:東京都港湾局 * Department of Natural Environmental Studies, Graduate School of Frontier Sciences, The University of Tokyo, Kashiwa, 277-8563, Japan ** Division of Earth Sciences, Natural History Museum and Institute, Chiba, 260-8682, Japan *** National Agriculture and Food Research Organization, Institute for Rural Engineering, Tsukuba, 305-8609, Japan **** National Institute of Advanced Industrial Science and Technology, Research Institute of Geology and Geoinformation, Geological Survey of Japan, Tsukuba, 305-8567, Japan + Present address: Bureau of Port and Harbor, Tokyo Metropolitan Government, Shinjuku, 163-8001, Japan 地学雑誌  Journal of Geography(Chigaku Zasshi)  128(6)905⊖92
