Figure 5. Depth profiles of (A) V, Ni; (B) Cu, Zn; (C) Mn, Rb; and (D) Ti concentrations. Sand layers and patches are indicated by the stippled bands in the profiles. Sand layers and patches based on visual core description and observation on X-ray radiographs by Tada et al. (Chap. 25, this volume) are indicated by the shaded bands in the profiles. The marine isotope stage (MIS) boundary (top panel) is based on Kennett et al. (Chap. 21, this volume).
