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...

Scientific or rule-of-thumb techniques of ground-water management--Which will prevail?
Charles Lee McGuinness
1969, Circular 608
Emphasis in ground-water development, once directed largely to quantitatively minor (but sociologically vital) service of human and stock needs, is shifting: aquifers are treated as possible regulating reservoirs managed conjunctively with surface water. Too, emphasis on reducing stream pollution is stimulating interest in aquifers as possible waste-storage media. Such management...
Revision of some of Girty's invertebrate fossils from the Fayetteville Shale (Mississippian) of Arkansas and Oklahoma
Mackenzie Gordon Jr., William J. Sando, John Pojeta Jr., Ellis L. Yochelson, I. G. Sohn
1969, Professional Paper 606
J.n 1910, G. H. Girty published a paper on the fauna of the Fayetteville Shale of northern Arkansas and northeastern Oklahoma in which he described 110 new taxa of fossil invertebrates. He did not, however, designate any type specimens or divulge the localities at which •the fossils were collected, nor...

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...
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...

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...
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...
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...
Quantitative comparison of some aesthetic factors among rivers
Luna Bergere Leopold
1969, Circular 620
It is difficult to evaluate the factors contributing to aesthetic or nonmonetary aspects of a landscape. In contrast, aspects which lend themselves to cost-benefit comparisons are now treated in a routine way. As a result, nonmonetary values are described either in emotion-loaded words or else are mentioned and thence forgotten.The...

Report on exploration of the Wadi Yiba copper prospect, Tihamat Ash Sham quadrangle, Kingdom of Saudi Arabia
Robert L. Earhart
1969, Open-File Report 69-83
The first phase of an exploration program at The Wadi Yiba copper prospect consisted of geologic mapping, prospecting, sampling, geophysical surveys, and diamond drilling. Copper mineralization is in a sedimentary rock sequence comprised mostly of siliceous, calcareous, and dolomitic rocks metamorphosed to the greenschist facies. The metasedimentary rocks are overlain...
