N2 - The depositional remanent magnetization of samples collected on ODP Leg 110 is partially overprinted by a magnetization acquired in the Brunhes and an enigmatic coring or sampling remanence. The overprint acquired in the Brunhes may be a result of deformation related to grain fabric modification or to diagenetic alteration of the remanence-carrying titanomagnetite, derived from volcanic ash. In some samples from Hole 671B the primary remanence is partially retained, leading to a polarity stratigraphy that correlates with part of the Pleistocene-Pliocene sequence. However, the polarity stratigraphy is of too poor a quality to enable any meaningful time constraints. In the section with steeply dipping bedding in Hole 671B the anisotropy of magnetic susceptibility can be used to correct the remanence inclination because of the unique relationship between geomagnetic north and the E-W compression direction at this site.
