内容 The Shimosa Group composed of marine sands periodically intercalated with thin beds of non-marine muds, sands and gravels, is distributed mainly in the northern Boso Peninsula, central Japan. Contents of the element B, K, Sr, Ca, Ni, Li, Sc, Cu, W, V, Ti, Co and Zn in the clay from the sediments are determined and discussed geochemically on their relationship to the sedimentary environments. As the results of this` study, following conclusions are obtained: (1) B, K, Sr and Ca are significantly more abundant in the marine than in the fresh-water sediments, whereas Sc, Cu, W, V, Ti and Zn are more abundant in the fresh-water sediments than in the marine ones. (2) It is indicated that the element B, K, Cu, Sr and Sc are especially good geochemical indicator for the discrimination between marine and non-marine sedimentary environments. (3) There is a positive correlation in Ca-Sr, Ti-Sc, Ti-V, V-W and Sc-Cu in diagram.
