Figure F23. Isothermal remanent magnetization (IRM) and backfield acquisition curves for representative discrete samples from Hole 1122C. A. Samples from above 250 mbsf, remanence saturates by 300 mT, and Bcr is between 50 and 75 mT. B. Samples from 300-400 mbsf, remanence saturates by 300 mT, and Bcr is <50 mT. C. Samples from beneath 400 mbsf, remanence does not saturate until nearly 1000 mT for samples from 483 and 457 mbsf, Bcr values vary between 25 and 75 mT. Remanence does not become saturated until 200-500 mT and Bcr is <50 mT for all samples.
