Figure 1. Chronostratigraphic correlation chart of Pennsylvanian rocks in the Appalachian coal regions showing approximate positions of coal beds, coal zones, and key stratigraphic units. Ages from Gradstein and others (2004). Series, North American Stage, and Western European Stage names are from Subcommission on Carboniferous Stratigraphy (SCCS). General chart layout based on information from S.F. Greb (Kentucky Geological 

Survey, unpub. data., 2005). Detailed stratigraphic correlations are based on communications with State geological surveys and from source publications listed at the base of each stratigraphic column. Abbreviations are as follows: Fm., Formation; Ls., Limestone; Mbr., Member; Ss., Sandstone; sh., shale.

Sources:

Rice and others (1994a); Carroll (2004); Pashin (1999, 2004); R.E. Carroll (Geological 

Survey of Alabama, written commun., 2006); J.C. Pashin (Geological Survey of 

Alabama, unpub. data, 2006).

Notes for the column:

This section represents over 5,700 ft of Pennsylvanian strata in the Black Warrior 

basin. More than 8,000 ft of Pennsylvanian strata are present in the adjacent Cahaba 

and Coosa basins of Alabama.

None of the coal beds or coal zones shown in this column can be correlated with 

any certainty to coal beds or coal zones in the east-central and southern Tennessee 

section.

1

Thickness from R.E. Carroll (Geological Survey of Alabama, written commun., 

2006).

2

Brookwood coal zone contains Guide, Brookwood, Milldale, Upper Carter, Lower 

Carter, and Johnson coal beds.

3

Gwin coal zone contains Gwin and Thompson Mill coal beds.

4

Cobb coal zone contains Upper Cobb, Lower Cobb, and Thomas coal beds.

5

Pratt coal zone contains Pratt, Nickel Plate, Fire Clay, American, Curry, and 

Gillespie coal beds.

6

Mary Lee coal zone contains New Castle, Mary Lee, Blue Creek, Jagger, and 

Ream coal beds.

7

Black Creek coal zone contains Lick Creek, Jefferson, and Black Creek coal beds.

Notes for the column:

1

Tennessee Division of Geology uses coal bed names, but not formation names 

shown above.

2

Coal zones that contain many coal beds are shown in red; individual coal beds 

included in a coal zone are shown in black in descending order. Only names that are 

useful for correlation are shown. For a complete list of coal zones and coal beds in 

eastern Kentucky, see Chesnut (1997).

In descending order, the 11 coal beds are named the Upper Seaboard, Greasy 

Creek, Middle Seaboard, Lower Seaboard, Sewell B, Sewell A, Bandy, Upper 

Horsepen, Middle Horsepen, “C,” and War Creek.

Notes for the column:

1

Locally developed thin coal beds not shown.

2

Thickness from Rice and others (1994a).

3

Tentatively correlated between States.

4

Coal beds or coal zones below the type section of the Sharon Conglomerate 

cannot be correlated with any certainty to coal beds or coal zones in either the West 

Virginia section or the western Pennsylvania and western Maryland section.

5

Locally contains brackish-water fossils (Berryhill, 1963).

6

This stratigraphic interval is complex, and correlations between States are 

tentative.

Notes for the column:

1

Thickness from Arkle (1959).

2

Coal bed found only in Pennsylvania.

3

Thickness from Rice and others (1994b).

4

Thickness from Edmunds and others (1999).

(Pennsylvania Bureau of Topographic and Geologic Survey, written or oral commun., 

2006).

Notes for the column:

1

Coal beds or coal zones in this section cannot be correlated with any certainty to 

coal beds or coal zones in the western Pennsylvania and western Maryland section. 

All coal beds or coal zones are approximately located except Salem, Primrose, and 

Buck Mountain. Salem, Primrose, and Buck Mountain coal beds are probably 

equivalent to Pittsburgh, Upper Freeport, and Lower Kittanning coal beds, respectively (W.A. Bragonier, Pennsylvania Bureau of Topographic and Geologic Survey, 

oral and written commun., 2006). Coal beds and coal zones in the Pennsylvania 

anthracite region of east-central Pennsylvania cannot be correlated to specific coal 

beds and coal zones in the Main Bituminous field of western Pennsylvania.

Pine Creek sandstone member, Rockcastle Sandstone Member, and Livingston 

Conglomerate Member are mapped at surface but are not used in subsurface. 

Sewanee Sandstone and Warren Point Sandstone are absent from the Cincinnati 

arch.

This stratigraphic interval is complex, and correlations between States are 

tentative.

Sources:

Wilson and others (1956); Rice and others (1994a); Zurawski and Miller (2004); B.W. 

Miller (Tennessee Division of Geology, unpub. data, 2006).

Notes for the column:

1

Thickness from Rice and others (1994a).

2

Coal names from Cumberland overthrust sheet. Usage in northern and southern 

Tennessee coal fields may not correlate with type sections on Pine Mountain 

overthrust sheet (B.W. Miller, Tennessee Division of Geology, written commun., 

2006).

3

Section above Windrock coal is based on data from B.W. Miller (Tennessee 

Division of Geology, unpub. data, 2006). Section below Windrock coal is based on 

data from Wilson and others (1956).

4

Coals in the Gizzard Group, Crab Orchard Mountains Group, and Crooked Fork 

Group cannot be correlated with any certainty to coal beds or coal zones in the 

north-central Alabama section or the Kentucky section.
