註釋

Ordovician outliers on the Canadian Shield near Lake Timiskaming comprise four major lithic units; these units in ascending order are sandstone, shales, limestone and shales. Formation names are proposed for the four units which are all assigned to the Liskeard Group. The youngest formation is of Edenian age, the oldest is of Wilderness age.
