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.
