Figure F8. Typical results from isothermal remanent magnetization (IRM) acquisition and Lowrie three-axis IRM tests (Lowrie, 1990). A, B. Type 1 samples are found above ~98 mcd in Hole 1267A and results are consistent with a mixture of titanomagnetite and coarse-grained magnetite. C. Type 2 sediments are found below ~98 mcd and are consistent with predominantly coarse-grained magnetite only. D. Type 3 sediments are found between ~70 and 83 mcd and are consistent with a mixture of titanomagnetite, coarse-grained magnetite, and hematite.
