Fig. 6
Results of stepwise AFD experiments for the selected zircon samples. Normalized remanence intensity is plotted as a function of applied peak AF field. The IRM was roughly imparted to the north direction. The samples which had M NRM/M IRM values of a ~0.01, b ~0.05, c ~0.1, and d ~1 are shown as inverted triangle, diamond, triangle, and square symbols, respectively. (Insets) Orthogonal vector plots for stepwise AFD of IRMLTD. Closed and open symbols denote horizontal and vertical projections, respectively. Points corresponding to the remanence before AFD are shown as double circles
