Figure F9. Gamma ray attenuation (GRA) bulk density, magnetic susceptibility, and color reflectance (L*) data for the upper 20 mcd in Holes 1221A (black; left curve in each panel), 1221B (blue; middle curve in each panel), and 1221C (green; right curve in each panel) plotted vs. composite depth. The data from Holes 1221B and 1221C are offset by constants for illustration purposes. All data sets are smoothed with a nine-point Gaussian filter. Intervals with obvious flow-in or drilling disturbance are removed from the data sets (see Table T4, ).
