| Outline of Final Research Achievements |
A key frame of terrains in the Japanese Alps (JA) has been created by igneous and orogenic activities in the Quaternary period. However, we should pay more attention to the role of landslides in warm periods that affected the formation of the middle to small scale landforms in the JA. Although previous geomorphologists in Japan have emphasized glacial and periglacial processes in the late Pleistocene, relict forms produced by those processes are sporadic in the JA under the present condition. Topographies and deposits caused by glaciations sometimes resemble those derived from landsliding. However, simplification of methodology and introduction of new techniques in chronology help us to distinguish landslide topographies-deposits from glacial ones. Landslides have also related to the development of alpine lakes as well as unique vegetation patches. This study is successful in providing new facts of landslide features to geomorphology, Quaternary science, and geoecology in Japan.
