ID: 2184171
Callville Limestone

Age: Pennsylvanian (298.9 - 323.2 Ma)

Description: Medium-gray, fine- to medium- grained, medium- to thick-bedded limestone with cyclic interbeds of moderate-orange-pink calcareous siltstone, sandstone, and light-gray dolomite increasing in the upper third; commonly cherty and fossiliferous; Chaetetes coral is common in the upper part, whereas brachiopods and bryozoans are common in limestone beds throughout (Hintze, 1986); forms ledge-slope topography in the Beaver Dam Mountains and at Square Top Mountain, similar to the overlying Pakoon Dolomite; stratigraphically equivalent to the lower part of the Bird Spring Formation of southeast Nevada (Hintze and Axen, 1995); upper contact is placed at the base of the lighter- colored, non-fossiliferous dolomite beds of the Pakoon Dolomite; represents shallow-marine deposits (Welsh and Bissell, 1979); age from Welsh and Bissell (1979); about 1500 to 2000 feet (460–600 m) thick in the Beaver Dam and southern Bull Valley Mountains (Hammond, 1991; Hintze and Hammond, 1994; Hintze and others, 1994).

Comments: shallow marine

Lithology: Limestone, dolomite, siltstone, sandstone
