Approximate times of some of the most commonly reported geomagnetic excursions of the Brunhes Normal Polarity Chron.

  • Highlighted excursions are those most likely to be found in the western U.S.
  • Possible correlations of these to a sketch of the relative paleointensity curve of Guyodo and Valet (1999) are suggested.
  • VADM = virtual axial dipole moment.
  • Vertical dashed line is the critical value of intensity below which Guyodo and Valet (1999) consider several directional excursions to have occurred.
