Name Origin

The Davis Coal Member of the Spoon Formation (Owen, 1856, p. 41) is named for the Davis Mine, located half a mile east of Dekoven Station, Union County, Kentucky (Lee, 1916, p. 19, 30).

Other Names

It has also been called the No. 6 coal in western Kentucky.

Correlation

It is correlated with the Wiley Coal of western Illinois.

Extent and Thickness

The Davis averages about 4 feet thick across much of southern Illinois, where it has been mined by surface methods (Butts, 1925). To the north and west the coal, as a rule, is thinner.

Stratigraphic Position

In Illinois the Davis Coal has about the same distribution as the De Koven Coal, which it underlies by as much as 30-40 feet.
