Paleomagnetism of Metamorphosed Sudbury Dykes, Canada: Relevance to a Theory of Crustal Shortening across the Grenville Collisional Orogen
摘要
The 1.235 Ga ESE-trending Sudbury dyke swarm cuts Paleoproterozoic to Archean rocks,but at its SE end becomes deformed and metamorphosed by the;Ga Grenville orogen,a result of collision between Laurentia
