Implications of Early Devonian poles from the Canadian Arctic Archipelago for the North American apparent polar wander path
Lower Devonian red beds from the upper member of the Peel Sound Formation at Prince of Wales Island (Canadian arctic) yield two different paleopoles at 25N 099E and at 01N 091E, the first one being older than the second one. The magnetic directions from which the poles are calculated are derived fro...
