Figure F2. Plot of remanent intensity (A) before and (B) after 60-mT AF demagnetization and (C) volume magnetic susceptibility all as a function of sub-bottom depth in Hole 1070A. Upon demagnetization to 60 mT, a significant decrease in intensity and a shift of inclination toward negative values were observed, suggesting that drilling-induced magnetization is present. Horizontal axes are log scales.
