Trace Elements in West Virginia Coals

Stratigraphic Distribution of Uranium (U)

Chart of average uranium (U) content, in ppm on a whole coal basis, for each West Virginia coal bed in stratigraphic order (larger version) — Select the chart to open a larger version.

The stratigraphic distribution of Uranium (U) shows little variation in the coal beds of West Virginia with most coals averaging less than 2 ppm on a whole coal basis. Coal beds of the Lower Pennsylvanian show slightly higher uranium contents than coals of the Middle and Upper Pennsylvanian. Major West Virginia coals have low uranium contents. Individual samples of the Harlem, Redstone and Sewickley coals contained anomalous high uranium contents, with four Sewickley coal samples containing greater than 10 ppm (see cautionary note page).
