Figure F16. AF demagnetization of discrete Sample 178-1103A-31R-3, 3-5 cm. A. Orthogonal projection of the end-points of the remanence vector. Open and solid symbols represent the vertical and horizontal projections, respectively. The steeply inclined drill-string overprint was removed after AF demagnetization at 10 mT. B. Change in the intensity of remanence during AF demagnetization. C. Equal-area projection of the remanence vector during AF demagnetization.
