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.
