Camp Run Member

Age:

Devonian

Type designation:

Type section: The Camp Run Member of the New Albany Shale was named by Lineback (1968, 1970) for exposures of greenish- to olive-gray shale interbedded with brownish-black pyritic fissile shale along the south side of Indiana Highway 311 at the Interstate Highway 65 overpass west of Sellersburg, Clark County, Indiana (W¼S¼ lot 110, Clark's Grant) (Speed quadrangle) (Burger, 1970; Burger and Hasenmueller, 1986). The name was taken from Camp Run, a nearby creek (Burger, 1970; Burger and Hasenmueller, 1986).

History of usage:

Overviews: Overviews of the unit within the Illinois Basin are included in Hasenmueller (1993) and Hasenmueller and others (1994).

Description:

The Camp Run Member contains greenish- to olive-gray shale interbedded with brownish-black pyritic fissile shale. Dolomitic concretions as large as 2 ft (0.6 m) in diameter are commonly found in the darker beds (Burger and Hasenmueller, 1986). Lying above the Morgan Trail Member of the New Albany Shale and below the Clegg Creek Member, the Camp Run Member is fairly uniform in thickness throughout the shallow subsurface in southeastern Indiana and ranges from 24 to 28 ft (7.3 to 8.5 m) in thickness (Hasenmueller, 1982; Burger and Hasenmueller, 1986).

Boundaries:

The contact between the Camp Run Member and the underlying Morgan Trail Member is easily recognized in cores, but this contact is difficult to distinguish when using well cuttings or geophysical logs (Burger and Hasenmueller, 1986). Therefore, this member has not been mapped in most of the subsurface of Indiana (Burger and Hasenmueller, 1986).

Correlations:

On the basis of conodonts the Camp Run is correlated with part of the Grassy Creek Shale of Illinois (Lineback, 1968) (Burger and Hasenmueller, 1986). It is stratigraphically equivalent to part of the Grassy Creek Member of the New Albany Shale in northwestern Kentucky (Hasenmueller and Bassett, 1981) and to the middle part of the Gassaway Member of the Chattanooga Shale of Tennessee (Lineback, 1970; Hasenmueller and others, 1983) (Burger and Hasenmueller, 1986). The Morgan Trail and Camp Run Members are approximately equivalent to the Lachine Member of the Antrim Shale in the Michigan Basin (Sandberg, C. A., Hasenmueller, N. R., and Rexroad, C. B., 1994).

Biostratigraphic dating: Conodont biostratigraphy indicates that the Camp Run Member of the New Albany Shale is of Late Devonian (Famennian) age (Sandberg, C. A., Hasenmueller, N. R., and Rexroad, C. B., 1994). Conodonts from the Early crepida, Late rhomboidea, and Early marginifera Zones were recovered. Lineback (1968, p. 1,299-1,300) noted that the unit contained carbonized plant remains, silicified Callixylon, Lingula, and a few small pyritized gastropods and pelecypods.

Geologic Map Unit Designation:

Dnacr

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.)
