Figure F13. Whole-core magnetic susceptibility from Hole 1121B from the Bartington loop of the shipboard automated multisensor track, archive-half continuous measurements of NRM intensity and inclination before and after alternating-field demagnetization to 20 mT from the pass-though cryogenic magnetometer. Vertical and subvertical lines between 27-52 and 76-130 mbsf indicate intervals where measurements were not possible because of poor core recovery or nonrecovery. Polarity interpretation is given on the right. Black (white) shaded intervals indicate normal (reversed) polarity, and hatched shading indicates intervals where polarity could not be determined because of "flow-in," poor recovery, or nonrecovery. Interpretations of magnetochrons from correlation to the GPTS are labeled, where known (see discussion in text).
