Preliminary investigation of faults and folds along the inner edge of the coastal plain in northeastern Virginia
Robert B. Mixon, Wayne L. Newell
1976, Open-File Report 76-330
Four en-echelon northeast-trending structures, including southeast-dipping monoclines and northwest-dipping high-angle reverse-faults, have been mapped along the inner edge of the Coastal Plain in northeastern Virginia -- an area generally considered to be undeformed. Although displacements are small (15to 60 m), the structures markedly affect the present distribution and thickness of...
Geochemical prospecting for Carlin-type gold deposits
Sherman P. Marsh
1976, Open-File Report 76-335
Disseminated, Carlin-type, gold deposits are associated with a volatile suite of elements consisting of Hg, As, Sb, W, and sometimes, but not always, Au. Geochemical exploration for this type of disseminated deposit depends upon recognizing the significance of this volatile suite and interpreting it in light of other geologic and...
Interpretation of Landsat imagery of the Tanacross quadrangle, Alaska
Nairn R. Albert, William Clinton Steele
1976, Open-File Report 76-850
In this study of Landsat imagery for the Tanacross quadrangle, Alaska, two fundamentally different types of images were used: (1) a black and white, single band, Landsat mosaic of Alaska, constructed with images that are not computer-enhanced; and (2) various types of computer-enhanced Landsat images....
Ground-water levels in Wyoming, 1975
Wilbur C. Ballance, Pamela B. Freudenthal
1976, Open-File Report 76-598
Ground-water levels are measured periodically in a network of about 260 observation wells in Wyoming to record changes in ground-water storage. The areas of water-level observation are mostly where ground water is used in large quantities for irrigation or municipal purposes. This report contains maps showing location of observation wells...
Analysis of seismograms from a downhole array in sediments near San Francisco Bay
William B. Joyner, Richard E. Warrick, Adolph A. Oliver III
1976, Open-File Report 76-296
A four-level downhole array of three-component instruments was established on the southwest shore of San Francisco Bay to monitor the effect of the sediments on low-amplitude seismic ground motion. The deepest instrument is at a depth of 186 meters, two meters below the top of the Franciscan bedrock. Earthquake data...
Map showing drainage areas, Hartford South quadrangle, Connecticut
Mendall P. Thomas
1976, Miscellaneous Field Studies Map 487-E
Map shows stream systems and drainage areas that contribute streamflow to selected sites on streams.Drainage areas shown have not been adjusted for the manmade changes in the natural regimens such as storm sewers, diversion dams, canals, and tunnels....
The shallow aquifer : a prime freshwater resource in eastern Palm Beach County, Florida
Harry G. Rodis, Larry F. Land
1976, Water-Resources Investigations Report 76-21
The shallow aquifer underlies all of Palm Beach County and is the source of almost all fresh-water supplies in the eastern part of the county. It consists of mixtures of sand, shell sandstone, and limestone. In this area the concentration of dissolved solids in the ground water usually does not...
