Figure F25. Magnetic susceptibility and remanent magnetization intensity, declination, and inclination of discrete samples as a function of depth, Hole C0018A. Green = natural remanent magnetization (NRM), Blue = 30 mT AF demagnetization. NRM inclinations are biased toward high positive inclinations, suggesting drilling-induced magnetization. AF demagnetization to 30 mT can effectively remove this drilling-induced magnetization, as indicated by changes in its inclination and intensity. MSCL = multisensor core logger. MTD = mass transport deposit.
