Figure F31. A. Isothermal remanent magnetization (IRM) and backfield acquisition curves for seven discrete samples from Hole U1351B. Samples reach saturation between 300 and 400 mT, and coercivity of remanence (Bcr) ranges between 32 and 85 mT. B. Alternating-field demagnetization of IRM of the same seven samples. C. Same as B, but intensities are normalized to saturation IRM for each sample.
