Figure F26. A. Smoothed (21-cm Gaussian) spectral reflectance (L*) data for the upper 130 mcd from Site 1168. Holes 1168B and 1168C are offset from Hole 1168A by a constant (20 and 40 L* units, respectively). B. Smoothed (21-cm Gaussian) magnetic susceptibility data for the upper 130 mcd from Site 1168. Holes 1168B and 1168C are offset from Hole 1168A by a constant (10 × 10^-6 and 20 × 10^-6, respectively). C. Smoothed (21-cm Gaussian) GRA bulk-density data for the upper 130 mcd from Site 1168. Holes 1168B and 1168C are offset from Hole 1168A by a constant (0.1 g/cm³ and 0.2 g/cm³, respectively).
