Based on fundamental laws of physicochemical mechanics of disperse structures, a magnetorheological model of lithogenetic structures in open (far from land) regions of the Pacific Ocean is constructed. Special attention is given to the magnetization mechanism of bottom sediments below the water-seafloor interface. This process is most active in the so-called Tucker-Khramov zone, where strength properties of a suspension are either unobservable or weak. A quantitative model describing both the filtering (smoothing) of a geomagnetic signal and its time lag in the rheological Tucker-Khramov zone is proposed for sedimentary rocks of various water contents. In the lower part of the zone, the sediment is a thixotropic solidifying structure in which the spatial orientation of magnetic dipoles is fixed due to an increase in the strength properties of the soil.
