The origin of the Cree Lake "intrusives" and basic gneisses of the Kisseynew series, Sherridon area, Manitoba

Abstract

The writer was employed by the Geological Survey of Canada, during the summer of 1947, in mapping an area of Kisseynew gneisses north and west of Sherridon, Manitoba. This work was conducted under the supervision of Dr. J.M. Harrison of the Geological Survey. From him the writer learned about some of the unsolved problems concerning the origin of certain rocks in the Kisseynew series in the immediate vicinity of Sherridon. The Sherridon area had been mapped by Dr. J.D. Bateman in 1943, and using his map as a guide the writer spent a week in the autumn going over a small area in detail and collecting specimens for later examination. The results of this investigation are presented here.
