Figure F39. Depth-scale representation of the magnetic susceptibility (MS) record at Site 1264 between 170 and 260 mcd (early to early late Miocene, 11 to 23 Ma). Assuming a sedimentation rate of ~0.9 cm/k.y., the energy bands centered on the 0.36- and 0.9-cm depth scale may be linked to obliquity and eccentricity forcing, respectively. Modulations in the energy bands are probably related to changes in sedimentation rates.
