Figure F24. A. Smoothed (21-cm Gaussian) GRA bulk density data for the Eocene/Oligocene boundary interval in Holes 1172A (left) and 1172D (right). Hole 1172D is offset from Hole 1172A by a constant (0.2 g/cm³). B. Smoothed (21-cm Gaussian) spectral reflectance data (L*) for the Eocene/Oligocene boundary interval in Holes 1172A (left) and 1172D (right). Hole 1172D is offset from Hole 1172A by a constant (10 L* units). C. Smoothed (21-cm Gaussian) magnetic susceptibility data for the Eocene/Oligocene boundary interval in Holes 1172A (left) and 1172D (right). Hole 1172D is offset from Hole 1172A by a constant (30 × 10^-6 SI).
