Distribution of gold, tellurium, silver, and mercury in part of the Cripple Creek district, Colorado
Garland Bayard Gott, J. H. McCarthy, G.H. Van Sickle, J. B. McHugh
1967, Circular 543
Geochemical exploration studies were undertaken in the Cripple Creek district to test the possibility that large low-grade gold deposits might be found. Surface rock samples taken throughout the district indicate that the volcanic rocks between the productive veins contain an average of about 0.6 ppm (part per million) gold. In...

Are we running out of water?
Raymond L. Nace
1967, Circular 536
Water supplies are not running out, but time is getting short to stem waste of water and destructive exploitation of the environment before harm is done that may be irreparable. Most of the world's water is oceanic brine. Of the waters on the land, most is frozen in Antarctica and...
General field and office procedures for indirect discharge measurements
M. A. Benson, Tate Dalrymple
1967, Techniques of Water-Resources Investigations 03-A1
The discharge of streams is usually measured by the current-meter method. During flood periods, however, it is frequently impossible or impractical to measure the discharges by this method when they occur. Consequently, many peak discharges must be determined after the passage of the flood by indirect methods, such as slope-area,...

Flood information for flood-plain planning
Conrad D. Bue
1967, Circular 539
Floods are natural and normal phenomena. They are catastrophic simply because man occupies the flood plain, the highwater channel of a river. Man occupies flood plains because it is convenient and profitable to do so, but he must purchase his occupancy at a price-either sustain flood damage, or provide flood-control...

Measurement of peak discharge at dams by indirect methods
Harry Hulsing
1967, Techniques of Water-Resources Investigations 03-A5
This chapter describes procedures for measuring peak discharges using dams, weirs, and embankments. Field and office procedures limited to this method are described. Discharge coefficients and formulas are given for three general classes of weirs-sharp-crested, broad-crested, and round-crested-and for highway embankments and weirs of unusual shape. The effects of...
A simple mercury vapor detector for geochemical prospecting
William W. Vaughn
1967, Circular 540
The detector utilizes a large-volume atomic-absorption technique for quantitative determinations of mercury vapor thermally released from crushed rock. A quartz-enclosed noble-metal amalgamative stage, which is temperature controlled and is actuated by a radio-frequency induction heater, selectively traps the mercury and eliminates low-level contamination. As little as 1 part per billion...

Marine sediment sample preparation for analysis for low concentrations of fine detrital gold
H. Edward Clifton, Arthur Hubert, R. Lawrence Phillips
1967, Circular 545
Analyses by atomic absorption for detrital gold in more than 2,000 beach, offshore, marine-terrace, and alluvial sands from southern Oregon have shown that the values determined from raw or unconcentrated sediment containing small amounts of gold are neither reproducible nor representative of the initial sample. This difficulty results from a...

Geology and ground water of the Savannah River Plant and vicinity, South Carolina
George E. Siple
1967, Water Supply Paper 1841
The area described in this report covers approximately 2,600 square miles in west-central South Carolina and includes the site of the Savannah River Plant, a major production facility of the U.S. Atomic Energy Commission. The climate, surface drainage, and land forms of the study area are typical of the southern...
Geology and hydrology between Lake McMillan and Carlsbad Springs, Eddy County, New Mexico
Edward Riley Cox
1967, Water Supply Paper 1828
The hydrology of the Pecos River valley between Lake McMillan and Carlsbad Springs, Eddy County, N. Mex., is influenced by facies changes in rocks of Permian age. Water stored for irrigation leaks from Lake McMillan into evaporite rocks, principally gypsum, of the Seven Rivers Formation and from Lake Avalon into...

1967, Water Supply Paper 1839-G
The present (1965) water use in Jackson and Independence Counties is about 55.6 million gallons per day, and quantities sufficient for any foreseeable use are available. Supplies for the large-scale uses--municipal, industrial, and irrigation--can best be obtained from wells in the Coastal Plain and from streams in the highlands....
A comparison of methods of estimating potential evapotranspiration from climatological data in arid and subhumid environments
R.W. Cruff, T. H. Thompson
1967, Water Supply Paper 1839-M
This study compared potential evapotranspiration, computed from climatological data by each of six empirical methods, with pan evaporation adjusted to equivalent lake evaporation by regional coefficients. The six methods tested were the Thornthwaite, U.S. Weather Bureau (a modification of the Permian method), Lowry-Johnson, Blaney-Criddle, Lane, and Hamon methods. The test...
