Figure F41. Depth-scale representation of the magnetic susceptibility (MS) record at Site 1267 between 320.9 and 367.5 mcd (Maastrichtian, 65 to 67.5 Ma). Assuming a sedimentation rate of ~2 cm/k.y., the energy bands centered on the 0.4- and 2.0-m depth scale may be linked to precession and eccentricity forcing, respectively. The 0.8-m energy band might be linked to obliquity but can also be related to changes in sedimentation rate.
