    Typical Pre-Cretaceous flysch type sediments, called the Yubetsu Group, are exposed on the northeastern part of the Hidaka Belt. The authors have done a three dimensional analysis of internal sedimentary structures utilizing the soft X-ray technique for paleocurrent study of the group. From the data obtained in this study the prevailing current direction in the turbidite of the study area is a lateral current from east to west with minor occurrence of axial current along north-south direction. Therefore, the provenance of the middle to upper Yubetsu Group of the present study is located to the east
