Long Range dikes

The Long Range dikes are a Neoproterozoic mafic dike swarm of Newfoundland and Labrador, Canada. It consists of a large igneous province with an area of 105,000 km2 (41,000 sq mi) that was constructed about 620 million years ago.[1] Its formation might have occurred when the ancient Iapetus Ocean began to form.[2]
