From introduction: This report deals with the Middle and Upper Carboniferous System.

Report discussing radioactive coal in northern West Virginia. From Abstract: "The commercially important coal beds in the Monongahela series of Pennsylvanian age and coal and shale of the Dunkard series of Permian age were examined and sampled in eight counties in northern West Virginia."

The following report covers a reconnaissance study that was made of radioactivity of coal and associated rock in the coal fields of eastern Kentucky and Logan Mingo counties, W. Va. Samples of coal, carbonaceous shale, marine shale, flint clay, and dike rock were discovered and radioactivity within these samples were measured.

Report discussing the U.S. Geological Survey's investigation of the radioactivity measurements of asphalltites, coals and shales found in Tennessee, Kentucky, West Virginia, and Pennsylvania.

Report discussing radioactivity measurements of samples of coal and associated rock that were collected during a reconnaissance study in the coal fields of eastern Kentucky, as well as Logan and Mingo counties, West Virginia.

Report discussing the U.S. Geological Survey's investigation of uraniferous coals and shales found in southern West Virginia and southwestern Virginia. Information regarding the general area, stratigraphy, structural geology, radioactivity of measured sections, radioactivity of collected samples, and conclusions are included.

From introduction: This report describes the deposits of analcite in the Green River formation, to compare them with other similar deposits, and to present them with other similar deposits, and to present the observations and inferences that led him to explain them as alteration products of volcanic ash that fell into an ancient saline lake. The report also records the occurrence of several thin beds of sepiolite, or meerschaum, in the Green River formation and presents new data on the molds of saline minerals of the Green River formation whose determination affects directly the interpretation of the analcite and sepiolite deposits.

The following report discusses the results of the mineral studies of national forest land in Cranberry Wilderness Study Area, Webster and Pocahontas Counties, West Virginia.

From abstract: This study used a rainfall-runoff model to determine if land-use changes associated with surface mining in the Tug Fork basin have affected basin streamflow characteristics.

The following report documents the geological mapping of the Harpers Ferry quadrangle, Virginia, Maryland, and West Virginia, from between 1989 and 1990.
