(Table 1) Paleomagnetic characteristics of sediments from ODP Leg 164 sites

The Blake Ridge, offshore South Carolina, was drilled at three sites, Sites 994, 995, and 997, during Ocean Drilling Program Leg 164. During the cruise, shipboard paleomagnetic measurements were performed to establish a magnetostratigraphy to refine age dates of the sediments. Shipboard measurements yielded a preliminary reversal stratigraphy (Shipboard Scientific Party, 1996, doi:10.2973/odp.proc.ir.164.1996). The routine paleomagnetic measurements of continuous core sections with the pass-through cryogenic magnetometer after alternating field (AF) demagnetization at 20 mT showed downhole inclination profiles with negative and positive intervals in the sections recovered with the advanced hydraulic piston corer (APC). The cryogenic results agreed with the results from analysis of discrete samples. The reversal stratigraphy was constructed based on the cryogenic and discrete sample results. […]
