抄録

The remanence properties of 62 cement samples from Cores 7R, 11R, and 12R recovered from Hole 648B were examined. The remanent magnetization consists of two components, where the soft component is carried by the basalt fragments in the cement sample and the hard component is carried by fine magnetic grains originally contained in cement. The hard component was used to estimate the variation of the magnetic field inclination within the hole. The result indicates that some parts of the basalt section within the sub-bottom depth between 15 and 20m are reversely magnetized, which can be attributed to the displacement of pillow basalt after its solidification. -Authors
