A Study of Lime-rich metamorphic rocks from Cree Lake, Manitoba.

Antrobus, Edmund Shakerley Alexander. January 1949 (has links)
The rocks studied in this thesis have been the subject of considerable discussion as to their original nature. J. D. Bateman of the Geological Survey of Canada considers that they are of igneous origin whereas others believe that they are metamorphosed sediments. It was thought that a petrographical study might provide some information that would help to decide the problem and it was with this object in view that this study was undertaken. Cree Lake, in the vicinity of which the rocks occur, is situated 2 miles North of the Sherritt-Gordon Mine, Manitoba, which lies about 20 miles east of the Manitoba-Saskatchewan border and 120 miles northwest of the north end of L. Winnipeg. The Sherritt-Gordon copper-zinc ore deposit is a very remarkable deposit in that it is a tabular body with a total outcrop length of 16,000 feet and an average width of 15 feet, thus being one of the longest exposed ore bodies in the world. The rocks in question outcrop around Found Lake which lies very close to and just to the southeast of Cree Lake (see Map 44-4) and fall into two groups; firstly, thos that outcrop south of Found Lake in an area which was mapped by J. D. Bateman as an oval body of oligoclase granite (Map 44-4, No. 12) about one mile long and 1/4 mile wide and secondly, those that outcrop as three smaller masses north of Found Lake but enclosed by the arms of Cree Lake and mapped as anorthositic gabbro (Map 44-4, No. 11).
