Mottles with chroma of 3 or more, or redox concentrations, are considered to be relic or litho-chromic. Mottles in shades of brown and yellow range from none to common. When matrix values are less than 3.5, thickness of the A horizon is less than 12 inches thick. Texture is clay or clay loam. The B horizons have colors in shades of brown and yellow hue of 7.5YR to 5Y, value of 4 to 7, and chroma of 2 to 8.
Mottles range from few to many in shades of gray, brown, yellow, and olive.
Reddish mottles range from few to many and occur in the upper B horizons, typically above the layers containing concretions or masses of calcium carbonate. Pitted concretions and threads or pockets of soft calcium carbonate range from 0 to 15 percent in the upper B horizons and from 3 to 20 percent in the lower B horizons. Some pedons have calcic horizons. Pressure faces and intersecting slickensides range from few to many, and generally increase with depth. There are no series in the same family, and the Billyhaw , Brazoria , Morse , Naclina , Tahoula , Vamont , and Zilaboy series.
