Figure F49. Occurrence of seven age-diagnostic calcareous nannofossils in the composite section from 0 to 500 mbsf (Holes 1201B and 1201D). The length of the horizontal bar at each depth level represents the abundance of nannofossils in four categories: rare, few, common, and abundant. The scale was set arbitrarily and is only meant to enhance visualization of the distribution patterns of the nannofossils in the succession. FO = first occurrence, LO = last occurrence. In the graphic lithology column, c = clay, s = silt, s = sand, g = gravel.
