Name
Original description
The Rosiclare Sandstone Member of the Aux Vases Sandstone (Ulrich and Smith, 1905, p. 24, 40; Swann, 1963, p. 80).
Derivation
Named for Rosiclare, Hardin County.
Other names
History/background
As originally defined, the Rosiclare Sandstone was a member of the Ste. Genevieve Limestone, and the name was widely misapplied to the sandstone now called the Spar Mountain Sandstone Member of the Ste. Genevieve. However, the type Rosiclare was found to be equivalent to the Aux Vases Sandstone (Swann and Atherton, 1948; Swann, 1963). The Rosiclare Sandstone has long been correctly correlated throughout the eastern part of the Illinois Basin, where it is an important oil producer. Consequently, the name "Rosiclare" is retained for a member of the Aux Vases.
Type section
Type location
The type section of the Rosiclare Sandstone Member is in the Ohio River bluffs just below the town of Rosiclare (NW SE and SW SE 5, 13S-8E).

Stratigraphic relationships
The Rosiclare is the main body of the Aux Vases in the area where it overlies the Joppa Member of the Ste. Genevieve and, therefore, does not include lateral equivalents of the Ste. Genevieve Limestone.
Extent and thickness
It is commonly 20-40 feet thick.
