Franklin Large Igneous Province

A Neoproterozoic Coronation Sill on the mainland south of Coronation Gulf, east of Kugluktuk. This is just one of dozens of parallel sills slicing through Nunavut's western mainland, each and every one with the same shallow dip to the north. They form a series of ramparts on land and many linear sets of islands out in the ocean.

The Franklin Large Igneous Province is a Neoproterozoic large igneous province in the Canadian Arctic of Northern Canada. It represents one of the largest large igneous provinces in Canada, consisting of the Natkusiak flood basalts on Victoria Island, the Coronation sills on the southern shore of the Coronation Gulf and the large Franklin dike swarm, which extends for more than 1,200 km (750 mi) across the Canadian Arctic Archipelago and northwestern Greenland.[1] The Franklin Large Igneous Province covers an area of more than 1,100,000 km2 (420,000 sq mi).[2]
