Abstract:
Magnetic properties are reported for samples from sediment cores recovered at Site 1081 on the Walvis Ridge (~20°S) during Leg 175 of the Ocean Drilling Program. Rock magnetic data indicate that the remanence is carried by low-coercivity minerals. Paramagnetic and diamagnetic minerals dominate the susceptibility. Comparison of measurements made aboard ship with those made on shore after the cruise indicate a marked loss of magnetization, probably due to dissolution of some magnetic minerals after core recovery similar to that which has occurred at other Leg 175 sites.
