Extending eastward from the Sault Ste. Marie area of Ontario, along the north shore of Lake Huron, thence northeastward through the Sudbury and Lake Wanapitei areas, to the Gowganda and Cobalt areas and on into the Province of Quebec, there is a belt of Algonkian rocks of Huronian age. They consist for the most part of clastic Sediments, quartzites, arkoses, greywackes, conglomerates and possibly tillites, with minor amounts of limestone and volcanic extrusive rocks. The rocks of this belt have been the subject of much study and many reports.
