In the artificial deposits prepared by experimental sediment discharge at Tateyama Caldera Sabo Museum, the maximum principal axis, ‘Kmax', of anisotropy of magnetic susceptibility (AMS), was found to be parallel to the current direction.The results indicated that the magnetic particles in the deposits were arranged in the current direction. This was concordant with observation under the reflecting microscope on the polished block of the deposit. The AMS study was also applied on the mountain stream deposits of the Kiso Mountains. The Kmax of AMS was parallel to the mountain stream direction which transported the deposits. The AMS method seems to be useful in the study of transportation and depositional process of sediment discharge.
