• The auther investigated terraces developing along the Iwami River, southeast of Akita City. The results are summerized as follows. (Refer to Figure 7, a model cross section of terraces.)The terrace surfaces of this region are classified into 8 levels. The highest and Tsubakidai (the fourth from the higher) terrace surfaces were formed at the stages of transgression. Each of them is the upper surface of littoral or estuarine deposits about 50m thick. Most of the other terraces are of fluvial origin and top of them consists of a veneer of gravel. Their surfaces were formed at the stages of regression.The properties of the terraces of this region, near the coast of Japan Sea, resemble to those of some regions on the coast of the Pacific Ocean, where the formation of terraces is often considered to have relations to the glacial eustacy.
