Whole-core magnetic susceptibility measurements define a detailed stratigraphy that enables correlation between the various Pleistocene, Pliocene, and upper Miocene sections cored on ODP Leg 110, near the Tiburon Rise. The magnetic susceptibility in these sections is primarily related to the content of volcanic ash, rich in titanomagnetite, and also inversely related to calcium carbonate content. The high resolution of the susceptibility record enables correlations with a resolution of about 0.3 m of sediment thickness, and the identification of minor faults not definable by biostratigraphic means. Reverse and normal faults identified in Hole 672A are probably a result of normal oceanic sediment dewatering and compaction processes. This work indicates some of the problems of using visible ash layers as time-stratigraphic markers.
