A fault running NW to SE is observed in the Saijyô Basin (broken line in the illustration). From the extension of fault line and the features of fault seen in a outcrop, it seems probable that the faulting along this line occurred intermittently since early Quaternary. The bearing with the tectonic line of NE-SW trend in the Chûgoku Mountains must be examined in relation to the formation of the Saijô Basin.
