Redeposition experiments of disintegrated hematite bearing sandstone have confirmed a tangent relationship between inclinations of the DRM and ambient magnetic field. Pronounced variations of DRM‐intensities with field inclination are attributed to processes acting during the depositional formation of laminated sediments. Coinciding azimuthal distributions of remanence and maximum susceptibility directions reflect intrinsic properties of flaky hematite grains in which the magnetic moment is parallel to the direction of maximum susceptibility. This parallelism probably depends on magnetic domain configurations.
