Chemical composition of sedimentary rocks in California and Hawaii
Thelma P. Hill (compiler)
1981, Professional Paper 1097
A compilation of published chemical analyses of sedimentary rocks of the United States was undertaken by the U.S. Geological Survey in 1952 to make available scattered data that are needed for a wide range of economic and scientific uses. About 20,000-25,000 chemical analyses of sedimentary rocks in the United States...
Dendroclimatic estimates of a drought index for northern Virginia
Larry J. Puckett
1981, Water Supply Paper 2080
A 230-year record of the Palmer drought-severity index (PDSI) was estimated for northern Virginia from variations in widths of tree rings. Increment cores were extracted from eastern hemlock, Tsuga canadensis (L.) Carr., at three locations in northern Virginia. Measurements of annual growth increments were made and converted to standardized indices...
Flow routing in the Susquehanna River Basin: Part IV - Routing reservoir releases in the eastern Susqehanna river basin in New York State
Thomas J. Zembrzuski Jr.
1981, Water-Resources Investigations Report 80-117
Flow-routing models for six reaches of major streams in the eastern Susquehanna River basin in New York were developed and used to trace releases of water from East Sidney Lake and Whitney Point Lake to gaged points downstream. Daily streamflow during 1942-77 was modeled for the following reaches: Susquehanna River--Unadilla...

Water Resources Division, U.S. Geological Survey
1981, Water Data Report ME-80-1
Water resources data for the 1980 water year for Maine consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of wells. This report contains discharge records for 61 gaging stations; stage only for 2 gaging...
Reconnaissance samplings and characterization of aquatic humic substances at the Yuma Desalting Test Facility, Arizona
Ronald L. Malcolm, R.L. Wershaw, E.M. Thurman, G. R. Aiken, D.J. Pinckney, J. Kaakinen
1981, Water-Resources Investigations Report 81-42
Smectite clay minerals were found to be the principal compound on the surface of the cellulose-acetate, reverse-osmosis membranes at the Yuma Desalting Test Facility. These clay minerals were not present in the pumped ground water, but were blown into the conveyance canal from adjacent soils. Humic substances from the water...
Results of hydrologic tests and water-chemistry analyses, wells H-4A, H-4B, and H-4C, at the proposed waste isolation pilot plant site, southeastern New Mexico
Jerry W. Mercer, Paul Davis, K.F. Dennehy, C. L. Goetz
1981, Water-Resources Investigations Report 81-36
Data were collected during hydrologic testing at wells H-4A, H-4B, and H-4C in the southern part of the proposed Waste Isolation Pilot Plant site in southeastern New Mexico. The three water-bearing zones tested, the Magenta and Culebra Dolomite Members of the Rustler Formation and the Rustler Formation-Salado Formation contact, yield...
Preliminary metallogenic map of North America: An alphabetical listing of deposits
Philip White Guild
1981, Circular 858-B
The names of 4,215 ore deposits shown on the Preliminary Metallogenic Map of North America are listed in alphabetical order by country, and by subdivisions of the larger countries (Canada, Mexico, and the United States). Map numbers, major and minor constituents, geographic coordinates, and a geologic code are given for...
