MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: MORGANTOWN, WEST VIRGINIA
SERIES ESTABLISHED: Wyoming County, West Virginia, 1984
REMARKS: (1) Itmann soils were previously mapped as a variety of strip mine spoil and udorthents units. (2) Carbolith is a name coined at West Virginia University to describe dark colored sedimentary rocks that will make a black or very dark (Munsell color value of 3 or less) streak or powder. Rocks under this name include coal not scheduled for mining, impure waste coal, bone coal, high carbon siltstones and high carbon shales.
Diagnostic horizons and soil characteristics recognized in this pedon are:
Ochric epipedon--the zone from 0 to 13 cm (A horizon)
Series control section--the zone from 0 to 200 cm
Carbolithic rock fragments make up 50 percent or more of the total rock fragment content in the particle-size control section.
The 8/00 revision updates this series to the 8th edition Keys to Soil Taxonomy standards. The CEC activity class placement is based on similar soils such as Sewell. The COMPETING SERIES section was also updated.
