Abstract
The Rocknest Formation (Fraser and Tremblay, 1969) is exposed in an area 200 km long and 100 km wide in the northwest corner of the Canadian Shield. It is part of the Ep-worth Group, which comprises the supracrustal rocks in the foreland fold and thrust belt of the Coronation geosyncline (Hoffman, 1973a). These rocks were deposited between 2,200 and 1,800 million years ago.
