The Churchill craton is the northwest section of the Canadian Shield and stretches from southern Saskatchewan and Alberta to northern Nunavut. It has a very complex geological history punctuated by at least seven distinct regional tectonometamorphic intervals, including many discrete accretionary magmatic events. The Western Churchill province is the part of the Churchill craton that is exposed north and west of the Hudson Bay. The Archaen (ca. 1.83 Ga) 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 with many remnants of Archean supracrustal and granitoid rocks.

Famous quotes containing the word churchill:
“There used to be housekeepers with more energy than sense—the everlasting scrubber; the over-neat woman. Since the better education of woman has come to stay, this type of woman has disappeared almost, if not entirely.”
—Caroline Nichols Churchill (1833–?)
