 Included within the Circum-Superior large igneous province are major nickel deposits of the Thompson and Raglan belts, which were likely derived from more than one magma source.The major 1,267‑million-year-old Mackenzie dike swarm magmatism in the western part of the Canadian Shield is the host for the highly prospected Muskox intrusion.Another significant event was the magmatism that formed the 723‑million-year-old Franklin dike swarm of Northern Canada and has been heavily mined for nickel, copper, and platinum group metals.
