Figure F144. Remanent magnetization before and after 30-mT AF demagnetization, as a function of depth. (A) Inclination and (B) intensity of archive halves from Section 210-1276A-35R-5 are shown. The natural remanent magnetization (NRM) inclinations are biased toward high positive inclinations, suggesting that drilling-induced magnetization is present. AF demagnetization by 30 mT can effectively remove this drilling-induced magnetization, as indicated by the changes in inclination and intensity.
