Overview

Excerpt from The Geology of Michipicoten Island The strata of which it is composed have a general dip to the east of south. And the inclination appears seldom to fall short of thirty degrees. The lower strata, toward the north side of the island. Particularly as indicated at the upper end, appear to be composed chiefly of amygf'laloidal trap, with occasional beds of trap-conglomerates. Red sandstones. And shales; wltile toward the south these are overlaid by a considerable amount of compact earthy or sub-resinous red trap, assuming, r sometimes an obscure and sometimes a distinct porphyritic character, by the display of ill-detittc'l crystals of red felspar or well-marked crystals of transparent colourless quartz.
