"The carbonate rocks of the Mississippian Ste. Genevieve Formation were studied megascopically in four quarries--Cave in Rock, Franklin, Three Rivers, and Fredonia Valley--within a small area of the Illinois-Kentucky fluorspar district and in a drill-core from the Cave in Rock Quarry. The rocks were studied microscopically in seventy-four thin sections prepared from samples from the quarries and the drill-core. The Ste. Genevieve Formation is typically an extremely oolitic, fragmentally fossiliferous limestone which is very light gray to white. The megascopic descriptions of the quarry exposures are presented as measured sections and columnar sections. A detailed log of the drill-core is in the Appendix. The stratigraphic terminology used in this thesis is based on D. H. Swann's recently revised nomenclature of the upper Mississippian rocks in Illinois. The exposed sections of each quarry and the drill-core were correlated. this correlation illustrates the pinching out of the Aux Vases Sandstone in the south and the varying thicknesses of the strata. The microscopic descriptions of the seventy-four thin sections are tabulated in a chart. They are classified according to R. L. Folk's (1959), carbonate rock classification. The implication of the observable features in the thin sections is that the Ste. Genevieve must have been laid down in a turbulent environment of strong currents or waves. The majority of the oolites were formed elsewhere and transported to the site of deposition. Minor oolitization did, however, occur at the site of deposition"--Abstract, page ii.
