| 内容記述 | The Niigata, Kashiwazaki, Takada and Kuninaka plains as well as the basins such as Muikamahi, Tokamachi, etc., are considered to have been formed during the Pleistocene. In these plains and basins, the areas where the topography changes often suffer mass-movement or some other upland disasters. The present writer has been working to clarify the time and process of the topographical changes in the Quaternary period. The anticlines that are developed in the mountainland and hills surrounding the plains and basins appear to have been cut at their boundaries (Fig.1). The writer and his colleagues interpreted this feature as a result of reverse faulting which occurred in the Late Pleistocene age (Fig.2). The recent investigation of the Niigata district, referring to the groundwater survey report of the Sanjo Area (1974), has disclosed that the geology of the Kamo and Sanjo areas is markedly discordant between the hilly part and the plain part, as is noticed in Figs.3 and 4. This may be ascribed to faulting which occurred much later than the deposition of the Yashiroda formation at least. But the time when the fault was active and the time when it was activated again are the subject for future research. As for the assignment of the Yashiroda formation, which has been a problem in the Niigata district awaiting solution, the writer in this paper insists that the formation does not belong to the Uonuma group as it is clearly distinct from the latter. His view is grounded on the fact that the Middle Pleistocene system of the Japanese Island has the characteristic red soil in two horizons and the Yashiroda formation is associated with the red soil (Table 1). Next, the writer infers that in the formative stage of the highーlevel terrace, which is correlatable with the Tama terrace of the Kanto district, the Niigata district already began to suffer the block-type faulting as shown in Fig.6, and the distinctive signs of plains, basins, mountains and hills of today were taking form. | |||||
