Age:Silurian Type designation:
Type section: The Liston Creek Limestone Member, originally having formation rank, was named by Cumings and Shrock (1927, p. 75) for exposures on Liston Creek in southwestern Wabash County, Indiana (NE¼SW¼ sec. 24, T. 26 N., R. 5 E.) (Shaver, 1970; Droste and Shaver, 1986).
History of usage:Change in rank: Pinsak and Shaver (1964) reduced the rank of the Liston Creek to that of a member of the Wabash Formation (upper part).
Description:At the type section, which is now under water in the Mississinewa Reservoir, the member consists of about 30 ft (9 m) of cherty limestone and dolomitic limestone that is light gray and tan, fine to medium grained, fossil fragmental, and slabby bedded and that rests with sharp, but probably conformable, contact on the Mississinewa Shale Member (Wabash Formation) (Shaver, 1970; Droste and Shaver, 1986). (See photograph in Shaver and others, 1961, fig. 6.)
Boundaries:The Liston Creek is underlain conformably by the Mississinewa Shale Member, and it underlies Middle Devonian rocks unconformably (except in the outcrop area); in some places in the area of Kokomo distribution, however, a thin Liston Creek member underlies the Kokomo member (Droste and Shaver, 1986). Correlations:The Liston Creek is a near equivalent of the Bailey Limestone in the Illinois Basin parts of Indiana, Kentucky, and Illinois (Droste and Shaver, 1986). It also corresponds to upper Racine rocks in northern Illinois and eastern Wisconsin, to upper Salina rocks (above the C unit) in the Michigan and Appalachian Basins, and to Salina rocks above the Vernon Shale in New York (Droste and Shaver, 1986). Considering the intimate intra-Wabash relations as described, parts of the Liston Creek variably correlate with Mississinewa, Kokomo, and Kenneth rocks in Indiana (Droste and Shaver, 1986). Probably only in the Illinois Basin does the relatively uneroded Liston Creek and Liston Creek-equivalent rocks have an age as young as that of the Bass Islands Group of the Michigan Basin and as that of the New York Silurian section ranging upward from the Bertie Dolomite (Droste and Shaver, 1986).
Economic Importance:Industrial Minerals: Crushed stone products from the Liston Creek Member (Silurian) include the following: crushed stone, dolomite, and limestone from quarries in Hamilton and Howard Counties (Shaffer, 2016). |

Misc/Abandoned Names:None Geologic Map Unit Designation:Swlc 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 terminologyNames 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.
