of a red granite in seams from 1/6 in wide to others 4 to 5 for thick. All are crossed faultily by small ones only the thinnest to several feet. The dark grey-green rock is much metamorphosed and in places is serpentinized. The granite sometimes appears to be mainly quartz with but little red felspars. Beside the veins of red granite there are included rounded blocks of the red granite now many feet apart. If this inference is correct the dark green masses are younger than the Grey Range granites, see the small collection of green rocks.
In going east a inland of Mac Dugarts from Clentam saw that the metamorphosed green rock gave way to pink and grey granite. We one all struck by the great variety of granites and freens here. Clentams notes say: "The granites include fine grained dark grey ones, light grey medium grained granite, coarse grained porphy with large phenocrysts of white felspar, coarse grained red and pink granites and granite breccia to compare to most of these types. The region must have had a complicated green history."
Today I am spending my sixtieth birthday geologizing in Newfoundland.
