Fluid-Inclusion Petrology - Data from Porphyry Copper Deposits and Applications to Exploration
J. Thomas Nash
1976, Professional Paper 907-D
Fluid-inclusion studies of 37 porphyry copper deposits, mainly in the United States, demonstrate that all but 3 evolved through a hydrothermal stage characterized by very high salinities, generally in excess of about 35 weight percent NaCI equivalent. Temperatures of these fluids ranged from about 250 deg to 700 deg C...
Water-quality effects on Baker Lake of recent volcanic activity at Mount Baker, Washington
Gilbert Carl Bortleson, Reed T. Wilson, B. L. Foxworthy
1976, Open-File Report 76-714
Increased volcanic activity on Mount Baker, which began in March 1975, represents the greatest known activity of a Cascade Range volcano since eruptions at Lassen Peak, Calif. during 1914-17. Emissions of dust and increased emanations of steam, other gases, and heat from the Sherman Crater area of the mountain focused...
Preliminary selection of storm-water basins suitable for infiltration of reclaimed water in Nassau County, Long Island, New York
D. A. Aronson
1976, Open-File Report 76-668
A survey was made of 205 storm-water basins south of the ground-water divide and north of Hempstead Turnpike in Nassau County, Long Island, N.Y., to determine which would be best suited for infiltration of reclaimed water. Selection depended on infiltration area, location with respect to the ground-water divide and to...

Ground-water resources of the Holloman Air Force Base well field area, 1967, New Mexico
W. C. Ballance, Robert E. Mattick
1976, Open-File Report 76-807
Water consumption at Holloman Air Force Base (HAFB), N. Mex., reached an all time high in 1964 and 1965. Further increases in withdrawal without expansion of pumping facilities will hasten the chemical deterioration of the ground water pumped from the well fields. Saline water in the well-field area is present...

The structure of a turbulent flow in a channel of complex shape
Hubert Jerome Tracy
1976, Professional Paper 983
Measurements of the Reynolds stresses and the mean motion pattern were made in a uniform turbulent motion in a conduit consisting of a large, nearly square section joined by a smaller rectangular section. The results indicate that the boundary shearing stress is nearly constant over large segments of the boundaries....
