Figure F79. A. Stepwise AF demagnetization up to 60 mT of Sample 183-1137A-26R-2, 55-57 cm. The sample has a high MDF and a single-component magnetization as is evident from the straight lines in the orthogonal vector projections. B. The MDF of Sample 183-1137A-38R-3, 105-107 cm, is very low as is evident from the decay curve (left). However, the orthogonal vector projection (right) shows a single-component magnetization with an inclination that is different from the present geomagnetic inclination. Hence, the remanent magnetization is not a recent overprint (see "Paleomagnetism"). J₀ is the magnetization intensity before AF treatment.
