A paleomagnetic investigation of the sudbury basin offsets, Ontario, Canada

The Sudbury offsets are a series of dike-like structures that appear either to radiate out from, or parallel the main Sudbury irruptive. In an attempt to establish the tectonic and magmatic relationship of these offsets to the main irruptive over 50 sites from 8 offsets were sampled for a paleomagnetic survey. From the over 10,000 measurements it is possible to derive a number of conclusions. First, the offsets are the end product of at least …
