The records document that the Laschamp Excursion was characterized locally by (1) declination changes of ± 120 °, (2) inclination changes of more than 140 °, (3) ~ 1200 - year oscillations in both inclination and declination, (4) near 90 ° out - of - phase relationships between inclinations and declinations that produced two clockwise loops in directions and virtual geomagnetic poles (VGPs) followed by a counterclockwise loop, (5) excursional VGPs
during both intervals of clockwise looping, (6) magnetic
field intensities less than 10 % of normal that persisted for almost 2000 years, (7) marked similarity in excursional directions over ~ 5000 km spatial scale length, and (8) secular variation rates comparable to historic
field behavior but persisting in sign for hundreds of years.
