Figure F26. Magnetostratigraphic record from Hole 1166A (0-320 mbsf). Plot of NRM intensity, inclination after demagnetization at 30 mT, and an enlargement of the polarity data for the interval between 80 and 160 mbsf (shaded area). The inclinations obtained from split cores are compared with inclinations from stepwise-demagnetized discrete samples (solid circles). Inclinations for discrete samples were determined by linear regression fits to multiple demagnetization steps. Polarity is shown on the log to the right. The depths of polarity boundaries and major disconformities are also indicated. Chron ages for polarity reversal boundaries are from Berggren et al. (1995). LO = last occurrence.
