Figure F8. Hysteresis ratios Mrs/Ms vs. Bcr/Bc plots (Day plots) for the Pacific-type, Transitional-Pacific-type, and Indian-type basalts from Leg 187, showing that most of the samples contain magnetic minerals ranging from SSD to PSD sizes. Plots of data for Site 1163 are incorporated with Site 1164. Three solid triangles plotted at the lowest right corner are the three massive basalt samples (#63, #65, and #67) from Hole 1160B. Four upside-down solid triangles plotted at the middle right side are four data points from the metadiabase sample (#74) from Hole 1162A. Ms = saturation magnetization, Mrs = saturation remanent magnetization, Bc = coercivity, Bcr = remanent coercivity.
