Figure F172. Summary of whole-round results (Fig. F171) for natural remanent magnetization (NRM) (0 mT) and 25-mT demagnetization, with declination shown by arrows and inclination shown by color. The steeper overprint in the central region is clearly visible in the NRM directions, and the coherent, shallow directions for 25 mT show nearly complete removal of the drilling overprint in the central region.
