Hysteresis loops, depth logs, and theoretical mixing curves. Magnetic hysteresis loops before (a, c, e, g) and after (b, d, f, h) paramagnetic correction; depth logs of low-field (i), paramagnetic (j), and ferrimagnetic susceptibilities (k); saturation magnetization (Ms) (l); and coercivity (Hc) (m) of selected samples from depths between 589.05 and 589.55 m in the WFSD-1 core. Hysteresis parameters, Mr/Ms, and Hcr/Hc are plotted on a plot by Day et al. (1977) with the theoretical mixing curves (n) (Dunlop 2002a, b).
