Discussion of the progress report of the Federal-Provincial Committee on Huronian Stratigraphy
It is argued that the term "Huronian", which has been, and still is, widely used as a time-stratigraphic term, serves a useful purpose in correlating the early Proterozoic rocks of Ontario with those of the Lake Superior region. It should not be used, therefore, as a rock-stratigraphic name of only local significance, as has been suggested in the progress report of the Federal-Provincial Committee on Huronian Stratigraphy, but be retained as an informal 'systemic' name pending clarification of conflicting results of age relationships of early Proterozoic rocks of the Great Lakes region. I A scheme of stratigraphic nomenclature is tentatively outlined for the early Proterozoic rocks of the Great Lakes region.
