The Cr is similar in color to the C and is interbedded quartzite and partially weathered quartz muscovite schist. It is sandy loam, loam or silt loam in the fine earth fraction. These are the Croom , Elliber , Gainesboro , Hartleton , Irondale , Lew , Mertz and Pattenburg soils. The Croom soils are formed in stratified gravelly Coastal Plain sediments. Elliber soils are formed in residuum from cherty limestone.
Gainesboro soils are in residuum from acid red shale, fine grained sandstone and silt stone.
Bedrock ranges from 20 to 40 inches. Hartleton soils are formed in glacial till derived from sandstone and shale and bedrock ranges from 40 to 60 inches. Irondale soils are in silty residuum from rhyolite bedrock and solum thickness ranges from 20 to 40 inches. Lew soils formed in colluvium from metabasalt greenstone. Mertz soils formed in colluvium from cherty limestones.
