Figure F5. Natural remanent magnetization (NRM) vs. low-field magnetic susceptibility (volume specific) of the Leg 187 basalt samples, which are grouped according to (A) mantle provinces and (B) tectonic zonations. Three data points from the massive basalt samples with susceptibility values ranging from 15 x 10-3 to 25 x 10-3 SI are outside the plot area.
