1989, Open-File Report 89-531
From 1984 to 1986, studies were conducted to assess the potential for undiscovered mineral resources in wilderness study areas on the Owyhee Plateau. The results of these studies have been published in a series of U.S. Geological Survey Bulletins. Since that time, low-grade, high-tonnage epithermal hot-spring gold-silver deposits have been...
Map showing the depth to the base of the deepest ice-bearing permafrost as determined from well logs, North Slope, Alaska
T. S. Collett, K. J. Bird, K.A. Kvenvolden, L. B. Magoon
1989, Oil and Gas Investigation Map 222
Because gas hydrates from within a limited temperature range, subsurface equilibrium temperature data are necessary to calculate the depth and thickness of the gas-hydrate stability field.  Acquiring these data is difficult because drilling activity often disrupts equilibrium temperatures in the subsurface, and a well mush lie undisturbed until thermal equilibrium...
Evaluation of methodology for delineation of protection zones around public-supply wells in west-central Florida
John Vecchioli, J. D. Hunn, W. R. Aucott
1989, Water-Resources Investigations Report 88-4051
Public-supply wells in the west-central Florida area of Citrus, Hernando, Pasco, Hillsborough, and Pinellas Counties derive their supply solely from the Floridan aquifer system. In much of this area, the Floridan is at or near land surface and vulnerable to contamination. Recognizing this potential threat to the aquifer, the Florida...
