Figure F29. Lower hemisphere equal area projection of dispersion of magnetization direction before and after demagnetization, Sections 315-C0001F-1H-2 and 315-C0001F-7H-4. N = direction of the single line at the bottom of the archive half (see Fig. F18 in the “Expedition 315 methods” chapter). Top diagrams show clustering of natural remanent magnetization (NRM) directions, with a downward and very steep mean direction. Remanence directions after 20 mT show a larger dispersion interpreted as core twisting.
