The anisotropy of magnetic susceptibility (AMS) has been recognized as a highly sensitive indicator of rock fabric and widely employed in the field of structural geology. The combination of rock magnetic measurements (e.g. low temperature and high magnetic field measurements) with nonmagnetic analysis (e.g., neutron texture analysis) demonstrates that magnetic minerals distribution has an important control on magnetic anisotropy. The integration of magnetic and mineral fabric analysis demonstrates to be a suitable tool to study strain mechanism on the grain scale and regional deformation pattern in claystones, even if macroscopic evidence is not visible at the mesoscale.
