The Sudbury dike swarm, also called the Sudbury dikes, is a Mesoproterozoic dike swarm in northeastern Ontario, Canada. With an age of 1,238 million years, it is younger than the Sudbury Basin impact event and predates the impact event that formed Lake Wanapitei.[1] References1. ^Using vertical dikes as a new approach to constraining the size of buried craters: An example from Lake Wanapitei, Canada {{Ontario-geo-stub}}{{Canada-geology-stub}} 4 : Dike swarms|Igneous petrology of Ontario|Geology of Greater Sudbury|Mesoproterozoic magmatism |
