Measurements of streamflow, ground-water levels, and meterological data obtained in a 4.1-mile reach of the flood plain of Cottonwood Wash, Mohave County, Ariz., define the use of water by riparian vegetation in that part of the stream valley. The computed evapotranspiration loss during the growing season of 1959 was 175...

In the interpretation of magnetic and gravity anomalies, downward continuation of fields and calculation of first and second vertical derivatives of fields have been recognized as effective means for bringing into focus the latent diagnostic features of the data. A comprehensive system has been devised for the calculation of any or all of these...

In 1955 exploration for base and precious metals was undertaken by Bear Creek Mining Company immediately north of the Main Tintic district, Utah. During the course of this work Bear Creek became interested in the East Tintic district, primarily as a result of the activities of the U.S. Geological Survey in...

A method is presented for using point mean precipitation data to estimate areal values in regions of high relief. Variation of precipitation with altitude is determined. Local anomalies from this relationship are mapped, and lines of equal anomaly are drawn. By use of the mean relation corrected for the local anomaly, the mean precipitation at...

A freshly exposed surface of obsidian will take up water from the atmosphere to form a hydrated surface layer. This layer has a different density and refractive index than does the remainder of the obsidian. Using special techniques, a thin section of the obsidian cut at right angles to the...

The investigation of the ground-water resources of Monmouth County is part of a Statewide water-resources program. This study was made by the U.S. Geological Survey in cooperation with the new Jersey Department of Conservation and Economic Development, Division of Water Policy and Supply. It was under the general direction of...

Design and uses are described of an easy-to-construct instrument that facilitates construction of profiles of land surfaces, geologic formations, or other features such as profiles of geophysical or geochemical anomalies. Response to data from users of the instrument indicates that it is both faster and more convenient than previous methods. ...

In natural radioactive sources the most important radioactive daughter products useful for geochemical studies are protactinium-231, the alpha-emitting thorium isotopes, and the radium isotopes. To resolve the abundances of these thorium and radium isotopes by their characteristic decay and growth patterns, a large number of repeated alpha activity measurements on...

The “acid nature” of humic acid has been controversial for many years. Some investigators claim that humic acid is a true weak acid, while others feel that its behaviour during potentiometric titration can be accounted for by colloidal adsorption of hydrogen ions. The acid character of humic acid has been...

The dye 2,2',4'-trihydroxyazobenzene-5-sulfonic acid, has shown promise as a reagent for the determination of zirconium. As the literature contains very little information about this dye, basic data pertinent to its use as a reagent were determined. The sulfonic acid group and all three of the hydroxy groups show acidic characteristics....

The thickness of the alluvial and tuffaceous deposits that overlie bedrock in Yucca Valley has been inferred from gravity and seismic measurements. Preliminary interpretations indicate that these deposits are thickest in a narrow north-trending trough in the eastern part of the valley. The gravity data delineate a buried north-trending ridge...

Thickness, grade, and depth data were obtained by analyzing gamma-ray logs and core samples from 56 diamond drill holes penetrating uranium deposits in the Colorado Plateau. The data from the two methods were compared to determine variations found in gamma-ray log interpretation and chemical and radiometric analyses of the drill core. Correlations within each parameter...

The estimated runoff from the Illinois River basin of 1,660 square miles has averaged 1,160,000 acre-feet per year during the water years 1938-56, equivalent to an average annual runoff depth of 13.1 inches. About 47 percent of the streamflow is contributed from drainage in Arkansas, where an average of 550,000...

A deposit of rare-earth minerals in the Scrub Oaks iron mine, Morris County, N. J., was mapped and sampled in 1955. The rare-earth minerals are mainly in coarse-grained magnetite ore and in pegmatite adjacent to it. Discrete bodies of rare-earth-bearing magnetite ore apparently follow the plunge of the main magnetite...

The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from activities of man. Some of the processes of...

The magnitude of a flood of a selected frequency for any point in the two states may be determined by methods outlined in this report, with two limitations. These methods are not applicable for regulated streams or for small-drainage areas (in general, less than 100 square miles). The determination of...

A hydrologic budget is a statement accounting for the water gains and losses for selected periods in an area. Weekly measurements of precipitation streamflow, surface-water storage, ground-water stage, and soil resistivity were made during a 2year period, April 1, 1950, to March 28, 1952, in the Beaverdam Creek basin, Wicomico...
