The Radiometric Age Data Bank (RADB) has been established by the U.S. Geological Survey, as a means for collecting and organizing the estimated 100,000 radiometric ages presently published for the United States. RADB has been constructed such that a complete sample description (location, rock type, etc.), literature citation, and extensive...

As part of a study of the geology and geophysics of the Charleston, South Carolina, area, thermal conductivity, thermal gradient, and heat flow were determined in a 742 meter, continuously cored, test hole. The hole is located 41 km west-northwest of Charleston near Clubhouse Corners, Figure 1, directly over a...

The application of subtractive compensation to USGS seismic magnetic tape recording and playback systems was examined in a recent USGS Open-file report (1). It was found, for the standard (30 Hz) NCER multiplex system, that subtractive compensation utilizing a 4688 Hz reference signal multiplexed onto each data track was more...

The distribution functions for hydrologic statistics that may be used to assess the significance of differences between sample means, standard deviations, coefficients of skewness, and coefficients of variations are obtained by Monte Carlo experiments. The distributions are expressed as functions of sample size, cross correlation, and skewness. In general, the...

Two-point seismic ray tracing is an important problem in seismology. In this report, we study this problem by first deriving the differential equations governing seismic wave propagation between two end points in a 3-dimensional heterogeneous and isotropic medium. We then formulate three numerical schemes to solve the two-point ray-tracing problem....

By 1995, the water table may fall by as much as 5 metres (16 feet) in east-central Nassau County and as much as 1.8 metres (6 feet) in central Suffolk County as a result of proposed sewerage programs. similar, but generally slightly less, change may occur in the potentiometric head...

The Hackensack River basin, in the northern part of the New Jersey-New York metropolitan area, includes some of the most highly urbanized areas in the United States as well as a largely undeveloped 23.4 square mile area of tidal marsh referred to as the Hackensack Meadows. Bedrock in the Hackensack...

Following two forest fires in the Roaring River drainage basin, Kings Canyon National Park, Calif., water samples were collected from May to July 1974 to determine water-quality changes resulting from the fires. Field measurements included alkalinity , pH, specific conductance, temperature, and discharge. Samples were analyzed in the laboratory for...

Irrigation has given a substantial boost to the economy in the Brooten-Belgrade and Lake Emily areas of Minnesota. The surficial outwash aquifer is capable of yielding sufficient quantities of water for irrigation over half of its area; the remaining part may be supplied by deep aquifers. Buried glacial outwash and...

The purpose of this report is to present information that may enable water users, potential water users, and planners to estimate the likelihood of obtaining ground water in adequate quantity and of suitable quality at desired locations within the study area. The Drain-Yoncalla area is in Douglas County in southwestern Oregon,...

The Lincoln County coastal area is underlain by Tertiary volcanic and sedimentary rocks of low permeability that store only a small volume of the annual precipitation which averages 68 inches (1,730 millimeters). Consequently, the Tertiary units yield small quantities of water to wells and furnish little ground-water discharge to maintain...

The U.S. Geological Survey Atlantic Margin Coring Project, 1976, a 60-day expedition to obtain core samples by drilling beneath the floor of the Continental Shelf and Slope of the eastern United States, was carried out in July, August, and September 1976 aboard D/V GLOMAR CONCEPTION. The coring penetrated as much...

The north-coast limestone area, about 600 square miles, is one of the few sparsely populated parts of Puerto Rico, and is the island 's last large and underdeveloped source of ground water. The area 's limestone aquifers are (from oldest to youngest): the Lares Limestone, the Cibao Formation, the Aguada...

This 3-sheet map report describes the hydrologic conditions in northwestern Wyoming. The increasing number of tourists and residents and the shifting of overnight accommodations for tourists from Yellowstone and Grand Teton National Parks to nearby areas may result in the need for development of additional water supplies in northwestern Wyoming....
