Type locality: The Ste. Genevieve Limestone was named by Shumard (1860, p. 406; 1873, p. 293-294) for exposures in the bluff of the Mississippi River south of Ste. Genevieve, Missouri (Smith, 1970; Carr, Rexroad, and Gray, 1986). At the type locality the formation is about 100 ft (30 m) thick (Carr, Rexroad, and Gray, 1986).
History of usage:
History of name in Indiana: The name “Ste. Genevieve Limestone” was mostly suppressed in favor of the term “St. Louis Limestone” until it was revived by Ulrich and Smith (1905) (Smith, 1970; Carr, Rexroad, and Gray, 1986). Beede and others (1915, p. 207) suggested that the Ste. Genevieve Limestone is present in Indiana, but it remained for Cumings (1922, p. 507) to use the name directly (Carr, Rexroad, and Gray, 1986). Before that time, rocks now designated as the Ste. Genevieve in Indiana had been assigned to the Mitchell Limestone (see under "Blue River Group") or to the Paoli or St. Louis Limestones (Carr, Rexroad, and Gray, 1986).
The Ste. Genevieve Limestone in Indiana is a carbonate-rock sequence that is 45 to 220 ft (14 to 67 m) thick and that thickens southward and southwestward (Carr, Rexroad, and Gray, 1986). Its constituent beds are composed largely of oolitic, skeletal, micritic, and detrital limestone (Carr, Rexroad, and Gray, 1986). Shale, dolostone, sandstone, and chert compose about 10 percent of the combined Paoli and Ste. Genevieve Limestones (Carr, Leininger, and Golde, 1978, p. 14; Carr, Rexroad, and Gray, 1986). The Ste. Genevieve crops out in a northward-narrowing belt from the Ohio River in Harrison and Crawford Counties to west-central Putnam County (Carr, Rexroad, and Gray, 1986). It is present throughout the Indiana subsurface south of the central parts of Parke and Vermillion Counties and west of its outcrop belt (Carr, Rexroad, and Gray, 1986).
Carr, Rexroad, and Gray (1986) noted that the correlation of the Ste. Genevieve Limestone of Indiana usage is beset with problems associated with the upper boundary, the lower boundary, and certain members of the formation.

Geologic Map Unit Designation:
Note: Hansen (1991, p. 52) in Suggestions to authors of the reports of the United States Geological Survey noted that letter symbols for map units are considered to be unique to each geologic map and that adjacent maps do not necessarily need to use the same symbols for the same map unit. Therefore, map unit abbreviations in the Indiana Geologic Names Information System should be regarded simply as recommendations.
COSUNA areas and regional terminology
Names for geologic units vary across Indiana. The Midwestern Basin and Arches Region COSUNA chart (Shaver, 1984) was developed to strategically document such variations in terminology. The geologic map (below left) is derived from this chart and provides an index to the five defined COSUNA regions in Indiana. The regions are generally based on regional bedrock outcrop patterns and major structural features in Indiana.
