Optical method for determining particle sizes of coarse sediment
John R. Ritter, Edward J. Helley
1969, Techniques of Water-Resources Investigations 05-C3
A particle-size analyzer was used to determine particle sizes of sediment by an optical technique based on an adjustable circle of light which determines the intermediate axis of the sediment particles shown on a photograph. Data from counting particles in various size ranges can be presented either in the form...

Water for the cities - The outlook
William Joseph Schneider, Andrew Maute Spieker
1969, Circular 601-A
Except perhaps for the arid Southwest, water resources are generally sufficient to meet the needs of cities for the foreseeable future. Cities will continue to expand and additional rural areas will be converted to urban and suburban complexes. Demands for urban water will continue to rise and this will place...
Metalliferous deposits near Granite Mountain, eastern Seward Peninsula, Alaska
Thomas P. Miller, Raymond L. Elliott
1969, Circular 614
New deposits of lead, zinc, and silver were found in a large altered zone 18 miles long and 2 to 5 miles wide near Quartz Creek west of Granite Mountain in the eastern Seward Peninsula, Alaska. New deposits of molybdenum, bismuth, and silver were found associated with a previously reported...

Measurement of discharge by the moving-boat method
George F. Smoot, Charles E. Novak
1969, Techniques of Water-Resources Investigations 03-A11
This chapter describes the procedures for measuring discharge in large streams by the moving-boat technique. During the traverse of a boat across a stream, a sonic sounder records the geometry of the cross section, and a continuously operating current meter senses the combined stream and boat velocities. These data are...

Movement of a solute in the Potomac River estuary at Washington, D.C., at low inflow conditions
James F. Wilson, Ernest D. Cobb, Nobuhiro Yotsukura
1969, Circular 529-B
The movement of a solute, as represented by a soluble fluorescent dye, was observed in the Potomac River estuary at Washington, D.C. The average net rate of downstream movement of the solute centroid was less than 0.6 mile per day. The movement of a solute is highly dependent on the...

Gold in minerals and the composition of native gold
Robert Sprague Jones, Michael Fleischer
1969, Circular 612
Gold occurs in nature mainly as the metal and as various alloys. It forms complete series of solid solutions with silver, copper, nickel, palladium, and platinum. In association with the platinum metals, gold occurs as free gold as well as in solid solution. The native elements contain the most gold,...
U.S. Geological Survey heavy metals program progress report 1968 - Field studies
Water Resources Division, U.S. Geological Survey
1969, Circular 621
The Heavy Metals program of the U.S. Geological Survey and the U.S. Bureau of Mines began in mid-1966 and thus at the end of calendar year 1968 was halfway through its third year. This progress report summarizes field studies carried out under the Geological Survey's part of the program during...
Mercury in soil gas and air--A potential tool in mineral exploration
Joseph Howard McCarthy, W.W. Vaughn, R. E. Learned, J. L. Meuschke
1969, Circular 609
The mercury content in soil gas and in the atmosphere was measured in several mining districts to test the possibility that the mercury content in the atmosphere is higher over ore deposits than over barren ground. At Cortez, Nev., the distribution of anorhalous amounts of mercury in the air collected...
Establishment of gold-quartz standard GQS-1
Hugh T. Millard, John Marinenko, John E. McLane
1969, Circular 598
A homogeneous gold-quartz standard, GQS-1, was prepared from a heterogeneous gold-bearing quartz by chemical treatment. The concentration of gold in GQS-1 was determined by both instrumental neutron activation analysis and radioisotope dilution analysis to be 2.61?0.10 parts per million. Analysis of 10 samples of the standard by both instrumental neutron...

Laboratory theory and methods for sediment analysis
Harold P. Guy
1969, Techniques of Water-Resources Investigations 05-C1
The diverse character of fluvial sediments makes the choice of laboratory analysis somewhat arbitrary and the pressing of sediment samples difficult. This report presents some theories and methods used by the Water Resources Division for analysis of fluvial sediments to determine the concentration of suspended-sediment samples and the particle-size distribution...
Hydrogeologic information on the Glorieta Sandstone and the Ogallala Formation in the Oklahoma Panhandle and adjoining areas as related to underground waste disposal
James Haskell Irwin, Robert B. Morton
1969, Circular 630
The Oklahoma Panhandle and adjacent areas in Texas, Kansas, Colorado, and New Mexico have prospered because of the development of supplies of fresh water and of oil and gas. The Ogallala and, in places, Cretaceous rocks produce fresh water for irrigation, public supply, and domestic and stock use through approximately...

Results of geological and geochemical investigations in an area northwest of the Chulitna River, central Alaska Range
C. C. Hawley, A. L. Clark, M.A. Herdrick, S. H. B. Clark
1969, Circular 617
Sedimentary and volcanic rock units of Paleozoic and Mesozoic age, faults, and elongate bodies of intrusive rock, particularly serpentinites, have a dominant northeasterly trend in an area northwest of the Chulitna River between Eldridge Glacier and Bull River. The serpentinites locally contain abnormal (as much as 0.5 percent) concentrations of...

1969, Circular 624
Analyses by a combination fire- assay-solution-optical-emission spectrographic method of 137 rocks from the Stillwater Complex, Mont., indicate that platinum, palladium, and rhodium are preferentially concentrated in chromitite zones. The A chromitite zone (21 samples) has an average of 988.9 ppb (pans per billion, 10-9) Pt, 2290.2 ppb Pd, and 245.9...

1969, Circular 611
An asbestos occurrence was discovered in a remote part of the Eagle quadrangle, Alaska, in the summer of 1968 during geologic reconnaissance in connection with the U.S. Geological Survey's Heavy Metals program. The exposed part of the deposit consists of large joint blocks of serpentine which are cut by closely...
