Summary:

New name is needed for the "Golconda" as recognized east of Todd Co., KY, and north into IN. Fraileys shale is proposed for the middle "Golconda," that is, the interval between Haney limestone (new) and Beech Creek limestone, wherever [Big Clifty] sandstone is insignificant or absent. Unit consists largely of shale with minor amounts of limestone and mudstone. It is typically 70 to 90 ft thick in IL with extremes of about 45 to 140 ft. 94 ft thick at type locality.

Summary:

Unit has not been formerly recognized in MO. Constitutes middle portion of Golconda Formation, corresponding to Fraileys Shale of Golconda Group in IL. In MO, Golconda does not include sandstone interval called Big Clifty in IL. Underlies Haney Limestone Member and overlies Beech Creek Limestone Member.
