Figure F73. Variation with depth of (A) natural remanent magnetization (NRM) intensity and (B) percentage of NRM intensity removed by 20 mT alternating-field demagnetization within Subunit IIC of Hole 1184A. Dashed lines = the pattern of gradual NRM increase and coercivity decrease within layers discussed in text.
