Figure F33. Downhole variation in magnetic properties and relationship to lithology and alteration. A. Lithology. B. Multisensor track (MST) magnetic susceptibility. C. Foliation intensity measured by the structural team illustrates regions where degree of serpentinization is high. D. Inclination direction of natural remanent magnetization (NRM). Red dots = value for demagnetized half core, purple circles = minicore sample values after demagnetization to remove drilling overprint, dashed lines = fault zones (see "Structural Relationships").
