Sediments from Leg 172 sites on the BOR exhibit nearly isotropic magnetic susceptibility with poor magnetic lineation and only slightly better developed magnetic foliation. Although ~50% of the lineation measurements and 75% of the foliation measurements from Sites 1057 and 1061 are probably statistically significant, error limitations make it difficult to confidently resolve downcore magnitude variations except for major foliation changes. The lineation axes are usually horizontal and zones of common polarity suggest some particle alignment may be occurring, but the intensity of the alignment does not follow glacial/interglacial patterns. The stronger foliation trends at Site 1061 show some variability that follows mean magnetic susceptibility and may indicate changes in sediment mineralogy. A weak circulation regime on the crest of the BOR may be partly responsible for the poor magnetic lineation, thus making it difficult to document circulation related sedimentary processes with magnetic fabrics at this location.
