In syenite pegmatite.
"The corundum-bearing pegmatite outcrops on a low knoll which is traversed by the road leading from Davis Lake to Norland, and in outcrops to the north and south of this road."
On the road on the boundary between concessions III and IV, in lot 12,
Lutterworth township, and north and south of it, corundum syenite-pegmatite
occurs as flat outcrops over an area 4 chains long from north and south and 2
chains wide. The corundum is present as deep-brown crystals ranging from
a quarter of an inch to one inch in diameter, the largest being 4 inches in length.
The amount of corundum present varies; some areas of the outcrop l foot in
diameter contain 10 per cent.; in the remainder of the outcrop the corundum
content is low or negligible. The average content may be 3 percent.
South of the road the corundum syenite-pegmatite grades into a graphic
granite-pegmatite. To the east and west the rocks exposed are granite or
hybrid gneisses with a gneissic structure trending north and south and dipping
30* to 45*E. To the north and northeast a few corundum crystals were found
in pegmatite bands in the gneiss, the last outcrop in which the crystals occur
was 12 chains from the road. One small outcrop at the edge of a swamp con
tained 25 per cent, corundum across 3 feet in a pegmatite. The corundum
syenite-pegmatite may be a sill trending north and south, not more than 2
chains in width.
Owing to the erratic distribution of the corundum and the small size of the
corundum-bearing pegmatite, the deposit is not of any economic importance.
This occurrence was discovered by B. Tett in 1905.
