Geomagnetic spikes on the core-mantle boundary

Geomagnetic spikes on the core-mantle boundary

Rapid and spatially localized geomagnetic field variations around 1000 BC are hard to reconcile with expected field behaviour arising from the core dynamo. Here, the authors show that the intensity spike is consistent with an intense flux patch on the core-mantle boundary (8–22°) located under Saudi...
