Figure F36. Representative vector end-point diagrams (Zijderveld, 1967) for sediment samples through stepwise AF demagnetization. All samples display a normal vertical component of magnetization caused by drilling that is removed after 5 mT demagnetization. A. Pass-through section measurement (Sample 344-U1412A-10H-2A, 17.5 cm). B. Corresponding discrete sample (Sample 344-U1412A-10H-2W, 17.5-19.5 cm). C. Normal polarity sample (Sample 344-U1412A-12H-2W, 55-57 cm). D. Reversed polarity sample (Sample 344-U1412A-6H-1W, 92-94 cm). Open and solid squares = projection of the magnetization vector end-points onto the vertical and horizontal planes, respectively. NRM = natural remanent magnetization.
