Seismicity map of the State of Alabama
C. W. Stover, B.G. Reagor, S. T. Algermissen
1979, Miscellaneous Field Studies Map 1059
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States (Algermissen, 1969) which have been recompiled and updated through 1977. The data have been reexamined and intensities assigned where...
A study of reservoir characteristics of the Nanushuk and Colville groups, Umiat test well 11, National Petroleum Reserve in Alaska
J. E. Fox, P. W. Lambert, Janet K. Pitman, C.H. Wu
1979, Circular 820
Cretaceous sandstones in the Umiat Anticline contain the largest volume of oil discovered to date in the National Petroleum Reserve in Alaska. Umiat test well 11, although dry and abandoned, penetrated the most complete sequence of Cretaceous rocks in the Umiat area. Cretaceous formations cored (oldest to youngest) were the...
The importance of dissolved free oxygen during formation of sandstone-type uranium deposits
Harry Clifford Granger, C. G. Warren
1979, Open-File Report 79-1603
One factor which distinguishes t, he genesis of roll-type uranium deposits from the Uravan Mineral Belt and other sandstone-type uranium deposits may be the presence and concentration of dissolved free oxygen in the ore-forming. solutions. Although dissolved oxygen is a necessary prerequisite for the formation of roll-type deposits, it is...
Modeling highly transient flow, mass, and heat transport in the Chattahoochee River near Atlanta, Georgia
Harvey E. Jobson, Thomas N. Keefer
1979, Open-File Report 79-270
A coupled flow-temperature model has been developed and verified for a 27.9-km reach of the Chattahoochee River between Buford Dam and Norcross, Ga. Flow in this reach of the Chattahoochee is continuous but highly regulated by Buford Dam, a flood-control and hydroelectric facility located near Buford, Ga. Calibration and verification...
Steady-state dissolved oxygen model of the Willamette River, Oregon
Stuart W. McKenzie, W. G. Hines, D. A. Rickert, F. A. Rinella
1979, Circular 715-J
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Water budget and hydraulic aspects of artificial recharge, south coast of Puerto Rico
J. E. Heisel, Jose Raul Gonzalez
1979, Water-Resources Investigations Report 78-58
An analog model was used to evaluate ground-water conditions on the south coast of Puerto Rico. Water levels during a normal period and during an extended drought were simulated. Recharge and discharge values are reported. The model was also used to evaluate the possibilities of using treated waste water to...
Interim data report on the geohydrology of the proposed waste isolation pilot plant site, southeast New Mexico
Jerry W. Mercer, R.B. Orr
1979, Water-Resources Investigations Report 79-98
Data collected at the proposed Waste Isolation Pilot Plant site in southeast New Mexico through September 1977 help define hydrologic conditions at the contact between the Permian Rustler and Salado Formations, and Culebra and Magenta Dolomite Members of the Rustler Formation. Preliminary calculations of transmissivity along the Rustler-Salado contact range...
The Alaskan Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Talkeetna quadrangle, Alaska
Bruce L. Reed, G.C. Curtin, Andrew Griscom, S.W. Nelson, D.A. Singer, W. C. Steele
1979, Circular 775
The Talkeetna 1° by 3° quadrangle, which consists of about 17,155 km2 in south-central Alaska, was investigated by integrated field and laboratory studies in the disciplines of geology, geochemistry, geophysics, and Landsat data interpretation for the purpose of assessing its mineral resource potential. Past mineral production has been limited to...
