Abstract

This thesis is concerned with the most promising molybdenite-rich area on the north coast of Labrador, Cape Makkovik peninsula. The area, although only 6 square miles in size, is part of the Labrador Uranium Province and its geology is similar to the Beaverlodge and Great Bear Lake camps in the western part of the Canadian Shield. -- In a reconnaissance along the Labrador coast in 1900, Daly referred to the glaciated peninsula as "a veritable museum of rock types". The map-area is underlain by an assemblage of folded metamorphosed quartzitic and amphibolitic rocks of Precambrian age which have been termed the Aillik Group. The degree of metamorphism has been largely dependent upon the original character of the rock and upon tectonic stresses which prevailed during deformation. A great number and variety of intrusive rocks ranging in composition from "amazonite" pegmatite to lamprophyre have been intruded at different times along major joint sets. -- After detailed megascopic and microscopic study, parentage has been determined for those metamorphosed and metasomatized (potash-bearing) rocks which have retained some of their primary features. The relative ages of the igneous rocks have been determined and these observations, combined with radioactive age determinations, may possibly be a means of chronological correlation with dyke systems in other parts of Labrador. -- The thesis is illustrated by figures and plates, and by a coloured geological map on a scale of 1 inch to 500 feet.
