Name Origin

The Haney Limestone (McFarlan et al., 1955, p. 18) is named for Haney Creek, Hardin County.

Type Section

The type section of the Haney Limestone overlies the type section of the Fraileys Shale in a bluff along Haney Creek (NE NE SE 9, 12S-10E).

Extent and Thickness

The Haney is 35.5 feet thick in the type section. The formation thickens from north to south (fig. M-40). It is 80-100 feet thick in much of Williamson County and even thicker in southern Jackson County, but it generally thins to less than 15 feet thick in Moultrie, Coles, and Cumberland Counties. In Washington County, the lower part of the Haney grades northwestward to shale, and the base of the Haney shifts to a higher horizon-the formation thinning from 60 feet or more to 35-40 feet.


The Haney is dominantly limestone, with a little interbedded shale. The limestone of the Haney is typically light gray to brownish gray or dark gray, coarse grained, and fossiliferous. Much of it is oolitic. In Randolph County a zone of white oolite about 20 feet thick in the Haney is informally called the "Marigold Oolite" (Sutton, 1934) for the village of Marigold, near which it is well exposed (SE 20, 5S-8W). In many places the oolitic beds alternate with non-oolitic beds or with shale. A little chert is commonly present in the Haney, and much of the limestone is shaly. The shale is dark gray and generally calcareous and fossiliferous. The individual limestone beds generally are markedly lenticular and are much less persistent laterally than are beds in the younger Chesterian limestones. In the southern part of the area, the Haney is characterized by an upper limestone unit about 25 feet thick, a middle shale up to 10 feet thick, and a lower limestone about 50 feet thick, the upper part of which is more shaly than the lower. To the northwest the Haney grades to a shale that cannot be readily distinguished from the overlying shale of the Hardinsburg or the underlying Fraileys.
