Shelburne dike

The Shelburne dike, also known as the Great Dike, is a large northeast trending Mesozoic diabase dike in southeastern Nova Scotia, Canada. It is 140 km (87 mi) long, although some evidence suggests it extends a further 60 km (37 mi) to the northeast to Sambro Island. The dike might have fed volcanoes in the Triassic period when the landscape was rifting apart during the breakup of supercontinent Pangaea.[1][2]
