A stratigraphic inventory was made of the Devonian-Mississippian black shales of Michigan for their possible future use as a source of oil or gas. Structure, contour and isopach maps were made to scales of 1/1,000,000 and 1/250,000. Lithofacies maps were constructed on the 1/1,000,000 scale. An east-west cross-section of central Michigan is included. A portion of eastern Michigan was mapped at the 1/250,000 scale to show bedrock topography, bedrock cover, and drilling depths to the Antrim. All structure, contour and isopach maps were contoured by computer. The remainder were drawn by hand. The major stratigraphic conclusions are: (1) a minor unconformity is probably present at the top of the Traverse limestone in western Michigan; (2) the Traverse shale has closer affinities to the overlying Antrim than it does to the Traverse limestone; and (3) the Antrim should probably be divided into an upper and lower Antrim with a tongue of Ellsworth shale coming in from the west to divide the Antrim.
