Summary:

Named the Pratter Shale Member of the Hinton Formation for Pratter Hollow, near Falls Mills, Tazewell Co., southwestern VA. Consists of grayish red shale interbedded with siltstone, limestone, and sandstone. Thickness is 20 meters. Overlies the Tallery Sandstone Member and underlies the Falls Mills Member, both of the Hinton Formation. The Pratter is of Late Mississippian age.

Summary:

Hinton Formation is divided into seven distinct lithologic members in the report area: the Stony Gap Sandstone Member at the base, the middle red member, the Little Stone Gap Member, the middle shale member of Englund (1968), the Tallery Sandstone Member, the Pratter Shale Member, and the upper shale member of Englund (1968). The Pratter consists of grayish-red shale with thin beds of siltstone, limestone, and very fine grained sandstone. Averages 40 ft in thickness and is normally the top member of the formation throughout the study area, underlying the Pride Shale Member of the Bluestone Formation. The upper shale member of the Hinton is present only in Tazewell Co. Age is Late Mississippian (Chesterian).
