The anisotropy of magnetic susceptibility as a method to study Quaternary deposits: theory and applications
The anisotropy of magnetic susceptibility is used as a geophysical method, based on the non-uniform magnetic properties of rocks, within which it exploits the individual types of minerals, their quantity, and distribution in the rocks. The anisotropy of minerals may be a result of their crystalline structure or the shape of mineral grains. If the anisotropy is connected to the shape of the minerals, as in the case of magnetite, the axis of maximum magnetic susceptibility is perpendicular to the grain long axis. This indirectly allows determination of grain orientation in the rocks studied. Therefore, this method can be used to reconstruct the directions of transport of rock components, such as in loess, fluvial or ice-dammed sediments, and to determine the directions of ice-sheet movement based on glacial till studies. The method is also used in tectonic stress reconstruction, complementing the results of palaeomagnetic dating or the logging of borehole cores. The rapid, inexpensive measurement of anisotropy of magnetic susceptibility along with low human error in measurement has made this method competitive with traditional research methods
期刊介绍：
The policy of the Geological Quarterly is to publish significant contributions of information and geological insight relevant to an international readership. The journal has been issued since 1957 at the Polish Geological Institute - National Research Institute and, at present, is the leading Earth sciences journal in Poland. All aspects of Earth and related sciences, and universal and broad regional rather than locally oriented topics are covered.
The journal is intended to be an international forum for the exchange of information and ideas, particularly on important geological topics of Central Europe.
