Abstract: The formation mechanism of the rock magnetic structure includes that volcanic, tectonic, and fluid activities caused the orientation alignment of magnetic minerals , changes of the alignment direction of minerals or of the original residual magnetism (mineral structure) of a part of minerals, the re-magnetization of directional aligned magnetic minerals under the influence of the earth's magnetic field at the time, or to give new magnetic characteristics. The rock magnetic structure reflects the dynamics of minerals at that time. The magnetic susceptibility anisotropy can be well used to analyze, display and restore the geodynamic process and is a good method and tool for studying geodynamics.

Keywords: magnetic structure; mineral particles; mineral composition; magnetic susceptibility anisotropy; geodynamics
