Figure F15. A. Natural remanent magnetization (NRM) within Hole 1232A before AF demagnetization. Notice the extremely high NRM intensities, especially within the APC section, and the high positive inclinations throughout. These inclinations are interpreted to be the result of a drill string magnetic overprint. B. NRM within Hole 1232A after 20-mT AF demagnetization. Notice the significantly reduced intensities (although still high in value) and significant shift of most inclinations to negative values. We interpret these results to indicate normal polarity (Brunhes Chron) throughout Hole 1232A.
