Geology and water availability of Cullman County, Alabama
Robert J. Faust, Patrick O. Jefferson
1975, Open-File Report 75-451
The Pottsville Formation of Pennsylvanian age underlies most of Cullaman County in northern Alabama. It consists mostly of interbedded sandstones and shales that dip southward about 40 feet per mile. The Bangor Limestone of Mississippian age underlies the Pottsville and crops out in a few valleys along the northern boundary of...
Evaluation and proposed study of potential ground-water supplies, Gallup area, New Mexico
William L. Hiss
1975, Open-File Report 75-522
The ground-water potential of 5 areas in central-western New Mexico within 85 miles (135 km) of Gallup, N. Mex. was evaluated by reviewing the published literature, inspecting aerial and space photographs, and interviewing ranchers and personnel employed by well-drilling and mineral-exploration companies by telephone. The San Andres Limestone and underlying...
Estimate of sediment discharges, Santa Ana River at Santa Ana and Santa Maria River at Guadalupe, California
Carl G. Kroll
1975, Water-Resources Investigations Report 74-40
The computed sediment discharge of Santa Ana River at Santa Ana for the water years 1968-71 was 11,700,000 tons (10,600,000 tonnes) of suspended sediment and 5,000,000 tons (4,500,000 tonnes) of coarse sediment. The computed discharge of Santa Maria River at Guadalupe for the water years 1969-71 was 9,500,000 tons (8,600,000...
Copper, lead, zinc, antimony, and arsenic in Pakistan
Max Gregg White
1975, Open-File Report 75-162
Copper localities that merit geological investigation are found in the western Chasai District, in North Waziristan Agency, and in the Salt Range in Mianwali and Sargodha Districts. No high-grade deposits have been .reported from these ,areas and if deposits are developed they will likely be low-grade, high-tonnage, disseminated deposits. Those...
Physical factors determining the fraction of stored energy recoverable from hydrothermal convection systems and conduction-dominated areas
Manuel Nathenson
1975, Open-File Report 75-525
This report contains background analyses for the estimates of Nathenson and Muffler (1975) of geothermal resources in hydrothermal convection systems and conduction-dominated areas. The first section discusses heat and fluid recharge potential of geothermal reservoirs. The second section analyzes the physical factors that determine the fraction of stored energy obtainable...
Niobium (columbium) and tantalum resources of Brazil
Max Gregg White
1975, Open-File Report 75-29
Most of the niobium resources of Brazil occur as pyrochlore in carbonatites within syenitic intrusives of Late Cretaceous to early Tertiary age in western Minas Gerais and southeastern Goils. Minor amounts of it are produced together with tantalum from columbite-tantalite concentrates from pegmatites and placers adjacent to them, in the...
Problems related to water quality and algal control in Lopez Reservoir, San Luis Obispo County, California
Richard H. Fuller, Robert C. Averett, Walter G. Hines
1975, Water-Resources Investigations Report 74-47
Lopez Reservoir is a multipurpose impoundment that was filled during a 30-week period following a series of intense storms during the winter 1968-69. The reservoir is used for flood control, water supply, and recreation, including swimming, fishing, and boating. At full pool Lopez Reservoir has a surface area of 974...
Ground water in the Grand (Neosho) River basin, Kansas and Oklahoma
Robert B. Morton, Stuart W. Fader
1975, Open-File Report 75-366
Ground water in the Grand (Neosho) River basin occurs in both consolidated rocks and unconsolidated deposits. Water for domestic and stock supplies generally can be obtained from wells in either of the above deposits. Water for municipal, industrial, and irrigation supplies generally can be obtained in limited quantities from the...
