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

Florida-Hatteras shelf and slope, and inner Blake Plateau

During 1976 more than 5000 kilometers (km) of seismic-reflection profiles were obtained on the Florida-Hatteras shelf and slope, and the inner Blake Plateau. From these data reflecting units were traced regionally (Paull and Dillon, 1979; Edsal, 1979), and the structure and stratigraphy of the shelf were determined This geologic subcrop map is based largely on the interpretation of Paull and Dillo
