magnetic fabric determination

Show Summary Details

Quick Reference

The determination of the petrofabric using magnetic methods. Generally it is the determination of the magnetic susceptibility ellipsoid, as this is dependent on the shape of magnetite grains or the crystalline alignment of hematite grains. The magnetic fabric may also be due to paramagnetic and diamagnetic materials. Some instruments may be sensitive to the anisotropy of electrical conductivity in the absence of ferromagnetic materials.
