Franklin Large Igneous Province
Introduction 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 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  across the Canadian Arctic Archipelago and northwestern Greenland. The Franklin Large Igneous Province covers an area of more than  and erupted more than 700 million years ago over the course of about two million years. Sulfur emissions during the eruption and weathering of the new rock following it may have contributed to a snowball earth event known as the Sturtian glaciation.
