The Barnett Shale (Mississippian) in the Delaware Basin has the potential to be a prolific gas producer. The shale is organic rich and thermally mature over large parts of the basin.

Abstract The Mississippian Limestone formed through complex structural, stratigraphic, and diagenetic processes involving subsidence, tectonic uplift leading to periodic subaerial exposure, changes in ocean chemistry, variability inherent with carbonate cyclicity, as well as postdepositional alteration. These geologic complexities led to significant heterogeneity and compartmentalization ...The Magdalen Islands archipelago is the single site in the north-central Gulf of St. Lawrence where surface exposures of the Windsor Group, an important Mississippian (Visean) marine marker ...Ozark Plateau. The Ozark Plateau region is the smallest in Kansas, covering just 55 square miles in the southeastern tip of Cherokee County and the state. It is, however, part of the much larger regional Ozark Plateau that extends tens of thousands of square miles into Missouri, Oklahoma, and Arkansas. In Kansas, the Ozark Plateau region is ...Land subsidence is the gradual or sudden lowering of the earth's surface due to natural or human-induced factors. This report provides an overview of the causes, effects, and management of land subsidence in the United States, with case studies from various regions.

The Mississippian Limestone ranges from between 49 to 171 feet (15 to 52 m) in thickness, while generally being thinner towards the southern part of the Tobosa Basin. The Barnett Shale is the second formation to have developed during the Mississippian Period. It consists mainly of silty brown shale and fine-grained sandstone and siltstone.Geologic unit mapped in Arizona: Brown to dark gray sandstone grades upward into green and gray shale, overlain by light to medium gray or tan limestone and dolostone.
