Figure F18. Plots of natural remanent magnetization (NRM) after alternating field (AF) demagnetization to 80 mT. A. Sample 347-M0065A-2H-2, 48 cm; 3.99 mbsf. B. Sample 347-M0065A-5H-2, 32 cm; 14.20 mbsf. C. Sample 347-M0065A-8H-1, 125 cm; 23.52 mbsf. D. Sample 347-M0065A-14H-2, 75 cm; 44.15 mbsf. Category 1 contains a very soft and shallow component, and the vector does not trend toward the origin. Category 2, 3, and 4 vectors trend toward the origin. More than 30% of the initial intensity of the Category 3 example remains after demagnetization at the 80 mT level. Open squares = vertical, solid squares = horizontal.
