内容記述 | The Noshiro coastal dune in Akita Prefecture, northeastern Japan, is classified as a superpositioning coastal dune and consists of five basic units composed of three aeolian sand units bounded by layers of humic soil. Topographical map survey on study area situated south of the Yoneshiro River revealed differences in topographical characteristics between the northern part of the dune and the southern part. In addition, field survey revealed differences in the number of humic soil layers in both the northern and southern parts of the dune. These differences cannot be entirely explained by the commonly accepted interpretation that crustal movement caused a dipping to the northeast in the vicinity of the research area. Another possible interpretation for the differences is explored here; that a shortage in the sedimentary supply from the beach to the southern coastal dune, which decreases southward from the Yoneshiro river mouth, promoted the formation of barchans. These are recognizable in topographic maps of the study area, and their accumulation has given the southern coastal dune a complex structure. |
