Abstract

The Meguma group, an apparently conformable sequence of slates and quartzites, extends over several thousand square miles with a thickness of 30,000 feet. Features indicating persistent current direction to the east, graded bedding, small scour and fill structures, convolute bedding, and large angular slate fragments in quartzite are described. Combined with their great lateral and vertical extent, these features fit well with an origin of deposition by turbidity currents.
