Figure F58. A. Age model and correlation of the composite magnetic polarity record for Site 1201. Magnetic polarity interpretations are given in Figure F57, and individual reversal ages are from Berggren et al. (1995). Solid line = line of correlation, undulating line = hiatus. LO = last occurrence, FO = first occurrence. Lithostratigraphic summary is from "Lithostratigraphy," and biostratigraphic datums are from "Biostratigraphy." In the graphic lithology log, c = clay, s = silt, s = sand, g = gravel. B. The 0-50 mbsf interval enlarged. The main features are discussed in "Sedimentation Rates" in "Paleomagnetism."
