Figure F23. Plots of natural remanent magnetization (NRM) after alternating field (AF) demagnetization to 80 mT A. Sample 347-M0059A-15H-2, 17 cm; 49.82 mbsf. B. Sample 347-M0059A-5H-1, 123 cm; 15.41 mbsf. C. Sample 347-M0059A-18H-2, 69 cm; 59.56 mbsf. Category 1 and 2 vectors trend toward the origin, whereas Category 3 vectors veer into a plane perpendicular to the last demagnetization axis, which is a sign of gyroremanent magnetization acquisition. Open squares = vertical, solid squares = horizontal.
