The Neogene distributed in the south district of Mt. Horaiji is studied stratigraphically. The result is as follows; (1) The ill-sorted conglomerated eveloped at the basal part of the Neogene System is pressumed to be a marginal conglomerate formed by collapse movement. (2) The disconformity pointed out by KATO (1962) is not found. (3) We found newly the angular disconformity between the Kuroze formation and the Oro formation. (4) We have a new difinition of the Hokusetsu and the Nansetsu subgroups on the basis of the angular disconformity (Table 1). (5) The upheaval movement forming the disconformity is greater in the south. (6) In the south district, there are many faults along the Median Tectonic Line. It is pressumed that the upheaval movement may have relation to the activity of these faults because it has no effect on the Nansetsu formation. (7) The collaspe basin is pressumed to be located in the area where the amount of denudation is the largest. (8) In the Shidara basin, there happened the formation of collaspe basin twice.
