Abstract:
Downhole magnetic field measurements were conducted in Hole 504B on the Costa Rica Ridge during ODP Leg 111. Three magnetic groups within oceanic basement at this site are tentatively defined, based on the interval mean values of the downhole magnetic field. Statistical analyses show that there are significant differences in the inclinations of natural remanent magnetization (NRM) among the three magnetic groups. Although this could be caused by various factors, we explain the inclination difference among the three groups by simple tectonic displacements of basement by faulting after its formation, about 5.9 Ma ago. Based on the intensities of NRM and inclinations measured in the basement core samples drilled in Hole 504B on DSDP Legs 69, 70, and 83 and ODP Leg 111, the investigated section of basement formation can be divided into three or four magnetic zones that parallel the zones defined by the downhole magnetic field, alteration, and lithology. Downhole magnetic field and paleomagnetic data generally correlate positively, in spite of some discrepancies. The magnetic susceptibility values of the core samples were used to derive the insitu NRM from the downhole magnetic field data.
