Name Origin

The Roodhouse Coal Member of the Carbondale Formation (Siever, in Wanless, 1956, correlation chart, pl. 1) is named for Roodhouse, Greene County.

Type Section

Roodhouse is near the type section (NW 21, 12N-11W) (Kosanke et al., 1960, p. 35, 47).

Correlation

It probably correlates with the Kerton Creek Coal in Fulton County.

Stratigraphic Position

It directly overlies the Pleasantview Sandstone, without an underclay.

Description

The coal is canneloid and, like the Kerton Creek Coal of southern Fulton County, occurs immediately above a channel facies of the Pleasantview Sandstone, apparently in channels that were not completely filled by the sandstone (Wanless, 1957, p. 98). The coal is as much as 5 feet thick near the center of the channels but is not present outside them.
