| contents | We present rock magnetic data on 10 samples recovered from ODP Hole 843B. The 95-m.y.-old basalts have moderately high magnetization values, and Curie temperature measurements show that these basalts have undergone systematic low-temperature oxidation. High values for bulk coercivity indicate that the remanent magnetization is likely to be stable over geological time, and low viscous remanent magnetization coefficients measured for these samples argue that acquisition of viscous remanent magnetization is not likely to be geologically important in these samples. Unfortunately, formation of the Hole 843B crustal section at the beginning of the Cretaceous Normal Magnetic Superchron does not allow any simple test of the hypothesis that a substantial component of chemical remanent magnetization, in the direction of the field present during oxidation, is added soon after formation (Raymond and LaBrecque, 1987, doi:10.1029/JB092iB08p08077). |
