Name Origin

The De Koven Coal Member of the Spoon Formation (Lee, 1916, p. 30, 31) is named for Dekoven Station, Union County, Kentucky, near which it is well exposed.

Other Names

The De Koven Coal is also called the No. 7 coal in western Kentucky.

Correlation

The De Koven is correlated with the Greenbush Coal of western Illinois.

Extent and Thickness

It occurs from a few to about 40 feet above the Davis Coal and is widespread throughout Williamson, Saline, and Gallatin Counties, averaging about 3 feet thick (Butts, 1925). It is also present to the north in the deeper part of the Illinois Basin, but there it is generally thinner. In Williamson County the De Koven Coal is split by a few feet of dark shale.
