Figure 3. Histogram of natural remanent magnetization (NRM) intensity values for discrete samples. A. Distribution of intensity values between 1 × 10-8 and 1 × 10-7 Am2/kg. B. Distribution of intensity values between 1 × 10-7 and 1 × 10-6 Am2/kg. Distribution of samples >1 × 10-7 Am2/kg decreases rapidly. Note change in frequency scale between the two histograms.
