| 内容記述 | The geohistorical investigation has been made on the two different kinds of large-scale mass movements in the eastern marginal region of the Niigata Sedimentary basin, i.e., the Gozu debris flows and the Aburuma-gawa landslides. The stratigraphic successions of these mass movement deposits show the following important characteristics common to the both. 1) These mass movements have occurred repeatedly at nearly the same sites since the Middle Pleistocene to the present. 2) During Middle Pleistocene and early Late Pleistocene time, the large-scale debris flows and the primary landslide occurred almost contemporaneously with the development of the mountain topography. The origin and development of these mass movements have been strongly controlled by the crustal movements since Middle Pleistocene time. The amount of upheaval of the Gozu Mountains in this period have reached about 1,000 m in maximum height. The rapid block upheaval of the Gozu Mountains and the Uonuma Hills with an increasing elevation had brought about the fracturing and collapse associated with faulting and successive erosive rejuvenation, and finally resulted in generation of the large-scale mass movements. The sea level lowering and periglacial process in the glacial epoch are not essential for the origin of mass movement in the region studied. | |||||
