There is a series of distinct breaks of hillslopes at the height of 30-70m in the hills situated at the north and west suburbs of Sendai City, which consist of flattopped erosion surfaces (150-100m) cutting Pliocene sandstone and shale. Above these breaks develop the foregoing landforms, e. g. high level valleys, concave slopes, and erosion surfaces; below the breaks, on the other hand, predominate present landforms, e. g. V-shaped valleys, Sohlen-kerbtal, and valley plains. Separated by the breaks these two kinds of forms co-exist in the hills discontinuously adjacent to each other.The breaks bring the slopes to have a two-cyclic form on their profiles, and indicate a front line of the area of fluvial erosion encroaching into the area of surface denudation. The breaks are favorably preserved in the hills near the main divide, due to a kind of locational conditions.
