The Geological Survey?s investigations of the Chattanooga shale in Tennessee and adjacent states on behalf of the U.S. Atomic Energy Commission consisted mostly of geologic studies and routine analyses of samples for uranium. In the course of the studies, however, other investigations were made, primarily to find answers to specific...

The sediment-transport characteristics of streams were determined in a 6,000-square-mile (15,500-square-kilometre) area of the Coastal Plain and Piedmont regions of eastern North Carolina during 1969-73. The study covered all or parts of 21 counties and included data for 28 sediment-sampling stations located in parts of 4 major river basins, the...

A water-quality assessment of the Rock Creek (Cass) watershed was made June 12 and 13, 1974. Nutrients were resampled November 7, 1974. Surface waters within the watershed were calcium bicarbonate types with very similar concentrations of major dissolved constituents. Samples collected June 13 contained between 7.4 and 14 milligrams per...

A water-quality assessment of the Jordan Creek watershed was made September 24 and 25, 1974. Surface waters within the watershed were calcium bicarbonate types with very similar concentrations of major dissolved constituents and specific conductance values. Streamwaters contained less than 0.26 milligram per litre dissolved nitrate (as N), 0.03 milligram...

Geochemical sampling in the contact zone between the Giants Range Granite and the Duluth Gabbro Complex along the South Kawishiwi River indicates the presence of extensive soil anomalies associated with the known Cu-Ni-Co-Ag mineralization in the basal part of the Duluth Gabbro Complex. A close spatial relationship was found between...

Annual recharge data obtained from historical records and mean-annual precipitation data computed from rainfall records were used to develop simple linear-regression equations for use in estimating annual recharge for seven subbasins in the San Antonio area. Adjustments were made to the precipitation parameter to account for the effects of year-end...
