Abstract
The anisotropy of magnetic susceptibility is measured in Kimachi sandstone, which is massive sandstone from Miocene Omori Group. Grain fabrics are also measured on three planes, they cross orthogonally, one is horizontal and others are parallel / vertical to the paleo-current direction which is rarely observed in a quarry. Measuring the grain fabrics, grain shapes on each plane are traced as ellipses, and long axes of them are measured. The most preferred orientation of long axes of the oval grains is ENE-WSW as same as the direction vertical to the paleo-current. The second preferred orientation of long axes of the oval grains is NNW-SSE as same as the direction of the paleo-current. The vertical direction, in which there is no preferred orientation of long axes, is as same as the direction of minimum magnetic susceptibility. It is cleared that Kimachi sandstone has anisotropy of grain fabrics, even if it seems massive one without bedding planes.
