Selmier Member

Age:

Devonian

Type designation:

Type section: The name “Selmier Member” of the New Albany Shale was first used by Lineback (1968, 1970) for greenish-gray to olive-gray shale exposed in its type section on the south wall of the Berry Materials Co. quarry in the NE¼NW¼ sec. 34, T. 7 N., R. 8 E., Jennings County, Indiana (Butlerville quadrangle) (Hasenmueller, 1986). The name was taken from the Selmier State Forest, which is 1 mile (1.6 km) northeast of the type exposure (Hasenmueller, 1986).

Geologic Map Unit Designation:

Dnas

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. (Click the maps below to view more detailed maps of COSUNA regions and major structural features in Indiana.)
