Name

Original description

The Browning Sandstone Member of the Spoon Formation (Wanless, 1939, p. 14, 78).

Derivation

Named for Browning Township, Schuyler County.

Type section

Type location

The type locality is located in Browning Township (18, 2N-1E) (Wanless, 1956, p. 10; 1957, p. 86).

Stratigraphic relationships

The Browning Sandstone Member is the youngest named member of the Spoon Formation.

Extent and thickness

The Browning Sandstone has been recognized only in western Illinois (Wanless, 1957), where it occurs in both channel and sheet facies and ranges from less than 3 to as much as 80 feet thick.

Lithology

In some places the channel facies is almost entirely sandstone that grades upward into shale, but in other places most of it is silty shale and siltstone.
