In order to explain why the magnetic directions of naturally and artificially deposited fine silts show deviations from the direction of the ambient field a theoretical model has been postulated of the process of deposition.
The deviations have been explained satisfactorily on the assumption that the sediment consists of quasi-spherical, non-cohesive particles which roll into hollows in the existing bed. A model of this kind provides a theoretical basis for the quantitative study of certain sedimentological questions which may be applied to the study of such problems as the apparent anomalous resistance to erosion of very fine grained sediments, their mechanism of compaction and the determination of current direction and velocity.
Since it does not depend on direct observation either visual or mechanical the magnetic method may be particularly fruitful for sediments of fine silt grade where such observation is very difficult.
