Name Origin
The Levias Limestone Member of the Renault Formation (Sutton and J. M. Weller, 1932, p. 430, 439) is named for Levias, Crittenden County, Kentucky. It was originally the uppermost member of the Ste. Genevieve Limestone and was introduced as a replacement of the earlier name "Lower Ohara," but it was assigned to the Renault Limestone when it was found to overlie the Aux Vases Sandstone.
Type Section
The type locality of the Levias Limestone Member is just east of the town of Levias (10-J-16).
Extent and Thickness
The Levias is well developed in and near Hardin County, but north and west of there it is not easily distinguished and it is recognized only sporadically north of Lawrence County and west of Franklin County. In Hardin County the Levias commonly is 10-25 feet thick, but it has a maximum thickness of 35 feet.
Description
The limestone is relatively pure, cross-bedded, medium- to coarse-grained, white oolite containing some pink and light green ooliths. It contains some fine-grained limestone, and a few feet at the base is sandy.
Fossils
The Levias Limestone contains Platycriniies penicillus and is the top of the Valmeyeran Series.
