Figure F9. Sudden changes in color index and other physical property logs mark lithostratigraphic unit boundaries (Wang, Prell, Blum, et al., 2000). The carbonate content was measured by Chen et al. (2002). Most rapid swings in these parameters can be attributed to unconformities, at least for the Oligocene
