Shale samples from four cores of the New Albany and Antrim Shales (Devonian) and from six cores of the Maquoketa Group (Ordovician), representing a broad geographic area of Indiana, have been analyzed for total organic carbon, total sulfur, pyrolysis yield (Rock-Eval), bitumen content, and illite crystallinity data. These data indicate that the New Albany, Antrim, and Maquoketa shales contain a sufficient quantity and quality of organic matter to be good petroleum source rocks. Bitumen ratios, Rock-Eval yields, gas chromatography of saturated hydrocarbons, and illite crystallinity data show that the Maquoketa shales have reached a higher level of thermal maturity than the New Albany and Antrim shales. The level of thermal maturity of the Maquoketa shales suggested a maximum burial depth considerably greater than the present depth.
