Figure F19. Comparison of natural remanent magnetization orientation before (NRM) and after (20 mT) peak field AF demagnetization. A. Nonmagnetic core barrels. B. Standard (magnetic) core barrels. Red circles = positive downward orientations, open circles = negative upward directions. Histograms show inclination in 10° bins. Note that these cores were not oriented with the Flexit tool. APC = advanced piston corer.
