2D GRAVITY AND MAGNETIC MODELLING OF THE MACKENZIE LARGE IGNEOUS PROVINCE PLUME CENTER REGION, NORTHWEST TERRITORRIES, CANADA.

The proposed plume center of the 1270Ma Mackenzie large igneous province (LIP) is defined by the focus of the Mackenzie radiating dyke swarm and is located off the coast of Victoria Island in NWT, Canada. It has been proposed that the intracratonic Amundsen Basin, which partially surrounds the Mackenzie plume center, may have formed because of decay of an unidentified mantle plume [1][2][3] which we suggest is the Mackenzie plume.
