Correlation of coal beds, coal zones, and key stratigraphic units in the Pennsylvanian rocks of eastern Kentucky

The Pennsylvanian rocks of the eastern Kentucky coal field unlderlie an area of about 27,000 square kilometers (see index map). Largely because of the size and stratigraphic complexity of the area, Huddle and others (1963, p. 31) divided it into six coal reserve districts (unofficial), utilizing state and county lines as well as geologic features, drainage areas, and cola producing areas.

Distribution of molybdenum in heavy-mineral concentrates, Richfield 1 degree by 2 degrees Quadrangle, Utah

The purpose of these maps is to provide the regional geochemical framework for the U.S. Geological Survey's Conterminous United States Mineral Assessment Program (CUSMAP) for the Richfield 1° x 2° quadrangle.  The regional sampling is designed to provide definition of broad geochemical patterns and trends which can be utilized along with geologic and geophysical data for the assessment of the mine
