The possible role of sulfate-reduction kinetics in the formation of hydrothermal uranium deposits
Charles S. Spirakis
1979, Open-File Report 79-673
As a sulfate-bearing, hydrothermal solution cools to less than about 200°C, kinetic factors prevent sulfate from entering into oxidation-reduction reactions. Consequently, the reducing effect of H2S (and other reduced species) is not balanced with the oxidizing effect of SO4= to the same extent as at higher temperatures. The result is...
Interpretation of thermoluminescence patterns around a Wyoming roll-type uranium deposit
Charles S. Spirakis
1979, Open-File Report 79-774
Thermoluminescence from quartz and feldspar grains in samples collected from the vicinity of a Wyoming roll-type uranium deposit show an increase in the importance of high-temperature thermoluminescence relative to low-temperature thermoluminescence of samples which are believed to be former positions of the migrating mineralized front. This effect is believed to...

Regional flood-frequency relations for west-central Florida
M.A. Seijo, R.F. Giovannelli, J. F. Turner
1979, Open-File Report 79-1293
This report presents regional relations for estimating the magnitude and frequency of floods on streams in west-central Florida. Flood prediction equations derived cover 20, 5-, 25-, 100-, 200-, and 500-year recurrence intervals. Annual floods for three geographic areas of west-central Florida were found to relate significantly to basin characteristics. Basin...
Petroleum source potential of rocks dredged from the continental slope in the eastern Gulf of Alaska

1979, Open-File Report 79-295
A bedrock dredging program by the R/V Sea Sounder in 1977 and 1978 along the continental slope in the eastern Gulf of Alaska revealed a previously unknown Eocene sedimentary sequence that includes argillaceous rocks with favorable petroleum source rock characteristics. Seven of 36 dredge hauls that sampled outcrop contain argillaceous...

An economic analysis of selected strategies for dissolved oxygen management: Chattahoochee River, Georgia
John E. Schefter, Robert M. Hirsch
1979, Open-File Report 79-412
Using the Chattahoochee River as an example, a method for evaluating the cost-effectiveness of alternative strategies for dissolved oxygen (DO) management is demonstrated. The conceptual framework for the analysis is suggested by the economic theory of production. The minimum flow of the River and the percentage of the total waste...
