abstract
Block fields are newly found around the Mt. Dake near the block fields of Kui and Yano. In this paper, we described the occurrence of these block fields and weathering grade of granite. The block fields at Kui and Yano were formed on the residual hill on the Sera surfaces. On the other hand, Mt. Dake is not surrounded by small-relief surface at present. However, Mt. Dake is one of residual hill on the Sera surface, because the surface has been eroded by the Ashida river. This means that formation of the block fi eld is closely related with weathering and the formation of small-relief surface.
