Variations of magnetic-mineral concentration and grain size with depth in core GH98-1232. a Relative variations of anhysteretic remanent magnetization (ARM) (red), saturation isothermal remanent magnetization (SIRM) (green), and magnetic susceptibility (k) (blue) after Yamazaki et al. (2003). b The ratio of ARM susceptibility (kARM) to SIRM. Smaller ratios are interpreted to be indicative of larger average magnetic grain sizes. Thin horizontal lines indicate depth horizons for samples for which datasets are shown in Figs. 3 and 4
