Type locality: The Dutch Creek Sandstone was named by Savage (1920, p. 175) for exposures along Dutch Creek in central Union County, southern Illinois (Droste and Shaver, 1986). No type section was designated (Collinson and Atherton, 1975).
History of usage:
Overview and assignment: Meents and Swann (1965) summarized the Dutch Creek occurrence and characteristics in southern Illinois and included the unit as a basal member of the Grand Tower Limestone (Droste and Shaver, 1986).
The Dutch Creek Sandstone Member is commonly a light- to dark-brown hard dolomitic limestone that has thin sandy streaks and discrete sand grains surrounded by a carbonate matrix and that grades downward into a foot or so of light-gray coarse-grained, tightly cemented sandstone at its base (Droste and Shaver, 1986). The sand grains are well rounded and frosted (Droste and Shaver, 1986).
The Dutch Creek Sandstone Member overlies both the New Harmony Group (Lower Devonian; conformably) and the Wabash Formation (Upper Silurian; unconformably) in southwesternmost Indiana (Becker, 1974, fig. 9) (Droste and Shaver, 1986).
The Dutch Creek coextends under the one name into Illinois and western Kentucky (with formation rank in the latter state) (Droste and Shaver, 1986). In Indiana and Illinois it correlates with (is in facies relation with) a lower part of the Geneva Dolomite Member (Jeffersonville and Grand Tower Limestones) (Droste and Shaver, 1986). The Dutch Creek is usually assigned an early Middle Devonian age, but part or all of it is probably late Early Devonian in age (Droste and Shaver, 1986). (See Boucot and Johnson, 1968, and Shaver, 1984.) Devera and Fraunfelter (1988) reported that the age is thought to be early Eifelian in southwestern Illinois and late Emsian in southeastern Illinois, southern Indiana, and western Kentucky.

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.
