Paleozoic 252.17 - 541 Ma ID: 3187973 | Paleozoic sedimentary rocks Age: Paleozoic (252.17 - 541 Ma) Lithology: Sedimentary rocks Reference: Chorlton, L.B.

Cambrian 485.4 - 541 Ma ID: 2870239 | Conasauga Formation Age: Cambrian (485.4 - 541 Ma) Stratigraphic Name: Conasauga Formation Description: Light to dark-gray finely to coarsely crystalline, medium to thick-bedded dolomite containing minor greenish-gray shale and light-bluish-gray chert. In the Columbiana area of Shelby County, the Conasauga is dominated by thin to medium-bedded, dark-gray dolomitic limestone and minor dark-gray shale. In Bibb County and southwestern Shelby County, the Conasauga consists of medium-bluish-gray fine-grained, thin-bedded argillaceous limestone and interbedded dark-gray shale. In the eastern Valley and Ridge the lower part includes dark-green to pale-olive fossiliferous shale with a few dark-gray limestone interbeds. Comments: Printed map describes units Cc and Ccl in same description, split them up here. Lithology: Major:{dolostone,limestone}, Minor:{shale,chert} Reference: Horton, J.D., C.A. San Juan, and D.B.
