Mississippian limestone.

The Mississippian limestone varies significantly in reservoir quality, with some zones characterized by higher porosity tripolite, other parts characterized by lower porosity chert, and some characterized by unaltered limestone. Lithologically, the Mississippian limestone consists of tripolite, chert, cherty limes tone and limestone. ...Coal beds and thin marine shale and limestone units are widespread and occur in most parts of the stratigraphic section.

These stylolites, like most, are bedding-parallel, and thus most likely formed due to the weight of the overlying rock. Calcite, the dominant mineral, goes into solution under pressure, and insoluble material, like organic matter and clay ...The Mississippian-Pennsylvanian unconformity (Fig. 4) is everywhere well developed across the region and is generally easy to pick on moderate to poor rock exposures. In many places, Lower Mississippian gray limestone is overlain by Lower to Middle Pennsylvanian red sandstone and mudstone. Rarely can any angularity be detected at outcrop scale.Thus, this resident of Burlington began to collect fossils from country underlain by perhaps the largest accumulation of crinoidal remains anywhere in the world, the Lower Mississippian Burlington Limestone. The study of fossil crinoids became a consuming interest for Charles Wachsmuth for the next 30 years.
