Geophysical and structural evidence for the presence of a central uplift in the South Range of the Sudbury impact structure

The Sudbury Structure formed as a large impact crater. The current roughly elliptical outcrop pattern shows that the originally near circular crater has been subject to post-impact deformation. Some features of the original crater morphology have been preserved. For example, the arcuate form of the North Range is explained by preservation of the crater wall. This study examines data from the South Range of the Sudbury Structure. Dip and dip …
