Stendal Limestone Member

Age:

Pennsylvanian

Type designation:

Type section: In 1970, Burger and Wier formally proposed the name “Stendal Limestone Member” and designated the type section in the SE¼NE¼SW¼ sec. 3, T. 3 S., R. 7 W. near Stendal in Pike County, Indiana.

Reference section: A reference section was designated in the NE¼SW¼ sec. 12, T. 3 S., R. 7 W. (Burger and Wier, 1970, 1986).

History of usage:

In several unpublished manuscripts, Wier proposed the name “Stendal Limestone Member” (of the Petersburg Formation) for the limestone previously known as the Houchin Creek cap (Weller, Henbest, and Dunbar, 1942, p. 32) or the Houchin Creek Limestone (Cooper, 1946, p. 16) that is exposed near Stendal, Pike County, Indiana (Burger and Wier, 1970, 1986).

Description:

The Stendal Limestone Member is a black limestone that is dense, argillaceous, and fossiliferous in places (Burger and Wier, 1970, 1986). It ranges from 1 to 3 ft (0.3 to 0.9 m) in thickness (Burger and Wier, 1970, 1986). It overlies a black shale, 1 to 3 ft (0.3 to 0.9 m) thick, which separates this limestone from the underlying Houchin Creek Coal Member (Burger and Wier, 1970, 1986).

Correlations:

The Stendal is probably correlative with the Hanover Limestone Member of western Illinois and with the black limestone overlying the Ruff Coal (Western Kentucky No. 8b) in Kentucky (Burger and Wier, 1970, 1986).

Geologic Map Unit Designation:

Ppbsd

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.)
