Figure F34. Progressive AF demagnetization displayed by vector end-point diagram (Zijderveld, 1967), lower hemisphere equal area projection, and normalized change in the intensity (Sample 315-C0001H-25R-2, 35–37 cm). Data points = magnetization vector for individual demagnetization steps projected onto horizontal (dots) and vertical (squares) plane. Dashed line = decay curve of vector difference sum. Note that most of the remanence has a very steep downward inclination, suggestive of drilling overprint.
