Book Description
Excerpt from An Historical Sketch of the Lake Superior Region to Cambrian Time The ancient formations 'south of Lake Superior may be grouped into five great divisions: the Basement Complex, the Lower Huronian, the Upper Huronian, the Keweenawan, and the Lake Superior Sandstone. These five divisions are separated by unconformities of great magnitude, two of them at least being of the first order. According to the classification adopted by the United States Geological Survey, the Basement Complex is Archean; the Lower Huronian, Upper Huronian and K-ewee nawan constitute the Algonkian for this region; and the Lake Superior Sandstone is Cambrian.
