The Iceland Basin excursion: Age, duration, and excursion field geometry

The Iceland Basin geomagnetic excursion coincided with the marine isotope stage (MIS) 6/7 boundary. The age and duration of the excursion, at seven North Atlantic sites with sufficient isotope data, are estimated by matching marine isotope stage (MIS) 7a–7c to a calibrated template. Two criteria for defining the excursion, virtual geomagnetic pole (VGP) latitudes
