The 3BC and 3C horizons have hue of 10YR to 5Y, value of 5 to 7, and chroma of 1 to 7 or it is mottled. They are silty clay loam, silty clay, clay or the channery analogues of these textures. In some pedons the shale is interbedded with siltstone or limestone. Siltstone channers range from 0 to 80 percent by volume. Up to 50 percent siltstone parafragments are also present in some pedons.
Reaction ranges from very strongly to slightly acid.
These are the Aaron , Goodson , Losantville , Miamian , Morrisville , Shircliff , Skrainka , Useful , and Vincent series. Aaron soils have a lithic contact from 40 to 60 inches. Goodson soils have mollic colors in the A horizon and have a base saturation of 60 percent or higher in the lower part of the series control section. Losantville soils have free carbonates from 8 to 20 inches and are more than 60 inches to a lithic or paralithic contact. Miamian soils have free carbonates at 18 to 40 inches and are more than 60 inches to a lithic or paralithic contact.
