Figure F16. A. Initial natural remanent magnetization (NRM) intensities within the uppermost 130 mcd (cored with the APC) in Holes 1232A, 1232B, and 1232C are compared to magnetic susceptibility values for Hole 1232A. The similarity between the NRM intensity prior to demagnetization and magnetic susceptibility suggest that the drill string magnetization is enhanced by the coarse terrigenous-rich sediments. B. Demagnetized NRM intensities (20 mT AF) within the uppermost 130 m in Holes 1232A, 1232B, and 1232C are compared to magnetic susceptibility values for Hole 1232A. C. Demagnetized inclinations (20 mT AF) for the uppermost 130 m of Holes 1232A, 12332B, and 1232C. The noisy intervals of reversed inclinations are not easily correlated between holes and are considered to result from variably removed drill string overprints.
