Geological Setting

Capsule Geology The area is underlain by northeast-southwest trending Paleozoic strata. The coal is reportedly found in the Beverly Inlet Formation (formerly known as the Griper Formation - GSC Bulletin 472), Middle to Upper Devonian in age. These rocks are comprised of sandstone, siltstone and shale.

Coal occurs in a disintegrated outcrop in a creek flowing into Kellett Strait at Stevens Head, Melville Island (GSC Memoir 332). A sample of the coal was collected and analysed and is ranked as high volatile B bituminous. Much of the coal here was in pieces up to 4 inches in size and it was felt that was probably the width of the seam in the area.
