Abstract
It is often that profile curves of the surface of mountainlands show the reliefs of the district more clearly than are done by mere morphological maps. Characteristics of surface features, such as peneplane-remnants, faultscarps, warping surfaces, etc., are emphasizee.
In this report, the author tried to classify these profile curves, but without success owing probably to lack of data. The Tanzawa Mountainland, from which the present profiles are taken, is known as being extraordinarily complicated in its fine structure of fault-line nets. Careful attention was paid to the ridges-profiles, that is, the longitudinal profile along the mountian ridges. These profiles when compared with those of rivers, seabottoms, summitlevels, etc., are far more irregular, and difficult to analyse. They alone, however, retain the profiles and point to any small abnormalities that may exist.
Some of the profile curves are shown in the figures, among which fig. 11 and fig. 13 indicate typically the step-faults and the horst respectively. Attempts were made to compare fault-scarps quantitatively.
