Figure F18. A. Orthogonal projection of the end-points of the remanence vector for Sample 178-1097A-27R-1, 34 cm. Open and solid symbols represent the vertical and horizontal projection, respectively. This sample has a shallow inclination. The direction becomes unstable at the 50-mT demagnetization step. B. Change in the intensity of remanence, normalized to the 0-mT (NRM) intensity, during AF demagnetization. C. Equal-area projection of the remanence vector during AF demagnetization.
