Figure F33. A. Isothermal remanent magnetization (IRM) and backfield acquisition curves for 10 discrete samples from Hole U1352B. Samples reach saturation between 400 and 600 mT, and coercivity of remanence (Bcr) ranges between 40 and 75 mT. B. AF demagnetization of IRM of the same 10 samples. C. Same as B, but intensities are normalized to saturation IRM for each sample.
