During the summer of 1949 the writer was engaged by the Labrador Mining and Exploration Company of Montreal on a survey party mapping an area in central Labrador and, in particular, a band of iron-bearing formation that runs through it. In the winter of the same year a petrographic study of the formation was undertaken at McGill University, by the writer, and is the subject of this thesis. The iron formation lies between the lakes Snelgrove, to the south east, and Comeback, to the north, both of which are situated within the Dyke Lake Sheet and lie in the concession of the above-mentioned company.
