Fig. 4. The intensity and direction of the permanent magnetism of core sample KV297 from depth 0-50 m. Both graphs have colours to represent different magnetisms; blue for negative inclination and green represents induced magnetism that is presented for comparison. The real declination of the permanent magnetism of core samples is not known.
