The general agreement of the GHMT polarities to the core paleomagnetic polarities demonstrates that, in broad terms, the GHMT polarities for the Leg 178 sediment drift sites are valid and may be used to complement the core results and for age interpretation in intervals where core was not recovered.
The sediment magnetization derived from the GHMT logs has a similar absolute value to the core magnetization before AF demagnetization; however, the GHMT results indicate that the sediment surrounding the borehole has not suffered a significant drill string overprint, unlike the core.
Comparison of time averaged Koenigsberger ratios in different sediment types shows that silty clays (from sediment drifts) have a fairly consistent paleomagnetic recording efficiency, whereas coarser-grained sediments can be less efficient by up to a factor of 10 than the silty clays.
