The Battery Rock Sandstone Member of the Caseyville Formation (Cox, 1875, p. 204).
Cox (1875, p. 204) wrote, “In Hardin County, below the mouth of the Saline River, and opposite the town of Caseyville, in Kentucky, the Conglomerate rises into a vertical wall known as the ‘Battery-rock,’ and forms here the western bank of the Ohio River.” As Cox (1875) described the “conglomerate,” it is 110 ft (33 m) thick, having a thin layer of shale and coal 50 ft (15 m) below the top and 180 ft (55 m) above river level. However, Cox (1875) did not actually name the “conglomerate” or trace it beyond the “type locality.


===Derivation===
===Derivation===
Named for Battery Rock, a bluff of massive sandstone on the west bank of the Ohio River in Hardin County.
Battery Rock is a bluff overlooking the Ohio River in Hardin County, Illinois. During the Civil War, the Union Army placed cannons here, commanding the river (Sneed 1977).

===History/background===
===History/background===
Although Owen (1856, No. 1 vertical diagram) introduced the name “Battery Rock coal,” no usage of “Battery Rock sandstone” older than J.M. Weller (1940) has become known. Neither Glenn (1912) nor Lee (1916) used the term in their discussions of the Caseyville type area. In his lengthy treatise on the geology of Hardin County, Stuart Weller (1920, p. 226) alluded only to “the massive cliff-making sandstone at Battery Rock landing.” Butts (1925, p. 40) used the same construction in discussing the geology of the Equality–Shawneetown area. Wanless (1939), who was exceptionally thorough in describing named Pennsylvanian units, did not name the sandstone, although he, like all the preceding authors, mentioned the Battery Rock coal.<br>
For his part, Weller (1940, p. 37) named the Battery Rock formation and described it as comprising the Battery Rock sandstone below and the Drury shale above. Wanless (1956, p. 5) used “Battery Rock (Lick Creek) sandstone or conglomerate” in the lower part of the Battery Rock cyclothem. Kosanke et al. (1960) established the present usage: Battery Rock Sandstone Member of Caseyville Formation.<br>
In summary, Cox (1875) described the sandstone at what became the type locality, Weller (1940) named it informally, and Kosanke et al. (1960) named it formally. The long-disused name “Lick Creek sandstone” assigned by Lamar (1925) actually has priority over “Battery Rock sandstone.”

==Extent and thickness==
The Battery Rock Sandstone, a prominent bluff-forming unit (fig. P-3A), is very well developed in Gallatin, Hardin, and Pope Counties, where it is 50-100 feet thick in a large area. It is also as much as 100 feet thick in the western part of the southern Illinois outcrop belt, but there it is more lenticular. Along the southwestern side of the Illinois Basin, the sandstone extends only as far north as Randolph County. In the subsurface to the north and northeast of the outcrop belt, the Battery Rock is difficult to trace because several other thick sandstone units occur in the lower part of the McCormick Group.

==Stratigraphic relationships==
The Battery Rock has been mapped extensively along the outcrop in southern Illinois, leading to the notion that this is a nearly continuous, tabular sand body of fixed stratigraphic position. However, comparison of the type and reference sections of the Caseyville Formation (Figure 2-2) raises doubts about the continuity of the unit. The interval between the Pounds and Battery Rock Sandstones at the type section is 315 ft (95 m), compared with a range of 33 to 110 ft (10 to 33 m) in the three reference sections. Keeping in mind that the Caseyville stratotype contains the type Battery Rock, the interval here is greater than almost anywhere else in the basin. Aside from lateral tracing of sand bodies, the geologist has no ''a priori'' method to identify the Battery Rock in a given outcrop or well. The second prominent sandstone below the top of the Caseyville is usually labeled “Battery Rock,” but where sand bodies lens out, miscorrelations are likely. Vertical “stacking” of two or more valley-fill sandstone bodies also introduces potential miscorrelations.
==Extent and thickness==
In geologic quadrangle maps at scale 1:24,000, the Battery Rock has been mapped from Johnson County, near Interstate 57, eastward through parts of Pope, Hardin, and southern Saline and Gallatin Counties, Illinois. It has also been mapped in a few places across the Ohio River, in Kentucky (Trace and Amos 1984). The Battery Rock can be identified in well records a short distance north of the outcrop, but the unit has not been mapped systematically through the subsurface. As mapped, the Battery Rock ranges in thickness from a feather edge to more than 100 ft (30 m). Owing to the discontinuous nature of fluvial sandstone that fills paleovalleys, sandstone bodies of different ages probably have been mapped as “Battery Rock.”


==Lithology==
==Lithology==
The Battery Rock is generally medium-grained sandstone, but at places it becomes coarse; almost everywhere it contains scattered quartz granules and pebbles, which in places form conglomerate beds. Although the Caseyville sandstones have been called conglomerates, the term "conglomeratic" is more appropriate.
Like the younger Pounds Sandstone Member, the Battery Rock forms a widespread escarpment of bold, rounded cliffs. Large-scale, unidirectional planar and trough cross-bedding is prominent. Lenses of quartz-pebble conglomerate may occur throughout the member, not merely at the base. Among sandstones of the Caseyville, the Battery Rock tends to be the coarsest, and it contains the largest and most numerous quartz pebbles. Pebbles 1 inch (2.5 cm) in diameter or larger are common in the Battery Rock but are only locally found in older and younger strata. Near the top, the grain size becomes finer and the bed forms smaller.

==Contacts==
==Contacts==
Contacts are seldom well exposed in the field. Where visible, the lower contact is commonly erosive. The upper contact may be sharp and planar to rolling, or it may be gradational from fine-grained, thinly bedded sandstone to siltstone or silty shale.

==Age and correlation==
==Age and correlation==
The Battery Rock is correlated with the lower Caseyville conglomerate, or Kyrock Sandstone Member, of western Kentucky and with the lower part of the Mansfield Sandstone of Indiana.
On the basis of the palynology of coal beds, Peppers (1996) placed the Battery Rock well down in the Morrowan Series, approximately equivalent to the Kyrock Sandstone in western Kentucky and the Hindostan Whetstone in southern Indiana. The Battery Rock is likely to be correlative with the upper part of the New River Formation in West Virginia, the Middlesboro Sandstone in the Cumberland Gap area, and (by interesting coincidence) the Bee Rock Sandstone elsewhere in eastern Kentucky (S.F. Greb, Kentucky Geological Survey, written communication, 2017).


==Environments of deposition==

Like other thick, pebbly sandstone of the Caseyville, the Battery Rock is believed to be largely fluvial sediment filling southwest-trending incised valleys. The upper part of the Battery Rock may transition into estuarine facies.

The Battery Rock Sandstone serves as a scenic backdrop for recreation in the Shawnee National Forest and various state parks. From the 1810s to the 1850s, commercially carved gravestones and millstones were made from Battery Rock sandstone.

Cox (1875, p. 204) wrote, “In Hardin County, below the mouth of the Saline River, and opposite the town of Caseyville, in Kentucky, the Conglomerate rises into a vertical wall known as the ‘Battery-rock,’ and forms here the western bank of the Ohio River.” As Cox (1875) described the “conglomerate,” it is 110 ft (33 m) thick, having a thin layer of shale and coal 50 ft (15 m) below the top and 180 ft (55 m) above river level. However, Cox (1875) did not actually name the “conglomerate” or trace it beyond the “type locality.”

Derivation

Battery Rock is a bluff overlooking the Ohio River in Hardin County, Illinois. During the Civil War, the Union Army placed cannons here, commanding the river (Sneed 1977).

Other names

The lower part of Lamar’s (1925) Lick Creek sandstone is believed to be the Battery Rock (Nelson and Weibel 1996).

History/background

Although Owen (1856, No. 1 vertical diagram) introduced the name “Battery Rock coal,” no usage of “Battery Rock sandstone” older than J.M. Weller (1940) has become known. Neither Glenn (1912) nor Lee (1916) used the term in their discussions of the Caseyville type area. In his lengthy treatise on the geology of Hardin County, Stuart Weller (1920, p. 226) alluded only to “the massive cliff-making sandstone at Battery Rock landing.” Butts (1925, p. 40) used the same construction in discussing the geology of the Equality–Shawneetown area. Wanless (1939), who was exceptionally thorough in describing named Pennsylvanian units, did not name the sandstone, although he, like all the preceding authors, mentioned the Battery Rock coal.

For his part, Weller (1940, p. 37) named the Battery Rock formation and described it as comprising the Battery Rock sandstone below and the Drury shale above. Wanless (1956, p. 5) used “Battery Rock (Lick Creek) sandstone or conglomerate” in the lower part of the Battery Rock cyclothem. Kosanke et al. (1960) established the present usage: Battery Rock Sandstone Member of Caseyville Formation.

In summary, Cox (1875) described the sandstone at what became the type locality, Weller (1940) named it informally, and Kosanke et al. (1960) named it formally. The long-disused name “Lick Creek sandstone” assigned by Lamar (1925) actually has priority over “Battery Rock sandstone.”

Type section

Type location

The type section is at the namesake bluff in Sec. 27, T11S, R10E, Hardin County, Illinois, and is part of the Caseyville type section (Figures 2-1 and 2-2).

Type author(s)

Lee (1916).

Type status

The bluff shows the sandstone well, but contact relationships are obscured. Lee’s (1916) description does not agree well with that by Cox (1875).

Reference sections

See reference sections for the Caseyville Formation (Figures 2-2 and 2-3).

Stratigraphic relationships

The Battery Rock has been mapped extensively along the outcrop in southern Illinois, leading to the notion that this is a nearly continuous, tabular sand body of fixed stratigraphic position. However, comparison of the type and reference sections of the Caseyville Formation (Figure 2-2) raises doubts about the continuity of the unit. The interval between the Pounds and Battery Rock Sandstones at the type section is 315 ft (95 m), compared with a range of 33 to 110 ft (10 to 33 m) in the three reference sections. Keeping in mind that the Caseyville stratotype contains the type Battery Rock, the interval here is greater than almost anywhere else in the basin. Aside from lateral tracing of sand bodies, the geologist has no a priori method to identify the Battery Rock in a given outcrop or well. The second prominent sandstone below the top of the Caseyville is usually labeled “Battery Rock,” but where sand bodies lens out, miscorrelations are likely. Vertical “stacking” of two or more valley-fill sandstone bodies also introduces potential miscorrelations.

Well log characteristics

Typical for sandstone, the Battery Rock exhibits either an upward-fining profile or a nearly uniform “blocky” profile on resistivity logs.

Fossils

Casts of logs occasionally are present.

Age and correlation

On the basis of the palynology of coal beds, Peppers (1996) placed the Battery Rock well down in the Morrowan Series, approximately equivalent to the Kyrock Sandstone in western Kentucky and the Hindostan Whetstone in southern Indiana.

Remarks

If the unit labeled “Battery Rock Sandstone” in the type and reference sections (Figure 2-2) actually is the same sandstone, the tectonic subsidence rate must have been markedly greater at the type locality than elsewhere.
