Churchill Craton

The Churchill Craton is the northwest section of the Canadian Shield and stretches from southern Saskatchewan and Alberta to northern Nunavut. The Archean Western Churchill province contributes to the complicated and protracted tectonic history of the craton and marks a major change in the behaviour of the Churchill Craton.

This consists of Archean supracrustal belts that preserve mostly Archean greenschist, hornblende and Proterozoic biotite. This section of the Churchill province was called the Ennadai-Rankin greenstone belt.
