Progress Report, October 1--December 31, 1977 Author: Costain, J.K. Year: 1978 Progress in the evaluation of low-temperature geothermal resources in the eastern United States utilizing geological, geochemical, and geophysical data is reported. Primary programmatic emphasis is now being placed on the confirmation of radiogenic resources beneath sediments of the Atlantic Coastal Plain. Collation of existing gravity and magnetic data available for the Atlantic Coastal Plain is complete, and modeling of selected negative gravity anomalies of the Cuffytown Creek (Edgefield) pluton, S.C., the Rolesville batholith, N.C., and the Petersburg granite, Va., is in progress. Maps showing the distribution of gravity stations for the states of Georgia, South Carolina, and North Carolina were prepared. A reconnaissance geologic map is being prepared of the Raleigh belt and Carolina slate belt rocks. The purpose of this study is to determine the relationship of the Rolesville batholith to the surrounding country rocks, and to provide a geologic base for the geophysical interpretation of Piedmont stratigraphy underlying Atlantic Coastal Plain sediments to the east Title: Evaluation and Targeting of Geothermal Energy Resources in the Southeastern United States.

The immediate goal is the economic development of geothermal energy in the eastern U.S. A paper by Lambiase, Dashevsky, Costain, Gleason and McClung summarizes estimated and measured temperatures at the base of the Atlantic coastal plain in New Jersey, Delaware, Maryland, Virginia and North Carolina based on geothermal gradients measured in 66 holes. The gradients range from 16 to 50 C/km. Basement surface temperatures at several locations are estimated to be above an economically useful 40C; the highest is 91C. From this information, the most promising and best documented area for development of geothermal energy chosen by the authors is the Delmarva peninsula near Crisfield, MD. This is the location of the first deep geothermal test well on the East coast which is to be drilled within a month Title: Evaluation and Targeting of Geothermal Energy Resources in the Southeastern United States.

Final Report, June 1, 1975--April 30, 1976 Author: Costain, J.K. Year: 1976 The results of heat flow determinations and a reconnaissance dipole electrical resistivity survey in Bath County are described. A geologic map was compiled based on published maps and supported by reconnaissance geologic mapping in areas where published maps were not available. A regional bipole--dipole electrical resistivity survey was made in order to detect the presence of resistivity lows that might be associated with a geothermal system at depth. A single hole was drilled to a depth of approximately 300 m (approx. 1000 feet) to obtain a heat flow value that is representative of the area. The data were used to attempt to arrive at a model that unambiguously explains the origin of the thermal springs Title: Geological and Geophysical Study of the Origin of the Warm Springs in Bath County, Virginia.
