Different types of minor faults are well developed in the lower part of the Miura group which is extensively distributed on the Boso and the Miura peninsulas, South Kanto, Japan. Although the characters of a minor fault are generally different in different places, each minor fault may probably be originated in unconsolidated or subconsolidated sediments. Minor fault of this kind is provisionally called "intraformational fault" by the writer. As to the mechanisms of origination of the intraformational faults in different places in Japan, many 'opinions have hitherto been expressed by some Japanese geologists. According to the writer's recent opinion, however, the principal mechanisms of origination of the intraformational faults in the lower part of the Miura group are as follows. 1) Differential subsidence of the sea-bottom which occurred during the deposition of strata. 2 Submarine sliding which occurred during the deposition of strata. 3) Differential compaction of strata caused by the lateral changes in rock-facies as well as in thickness of strata.
