1971, Basic Data Contribution 25
Precipitation depth-duration-frequency relations have been derived for the San Francisco Bay region, California. The regimen of precipitation in the region is such that depth-duration-frequency characteristics for a site are closely related to the mean annual precipitation for that site....

In a recent review of the nature of batholiths, Hamilton and Myers (1967) interpreted the Boulder batholith of western Montana to be "in effect a gigantic mantled lava flow .... only a few kilometers thick," that flowed, under a crust of its own ejecta, across a broad structural basin. Such...

1. Engineering geologic maps in the United States may be one map prepared as part of a larger study of environmental geology, individual areal geologic maps containing additional engineering geologic data, or engineering geologic maps of single construction sites.2. No systematic methodology for engineering geologic or environmental geologic maps has...

This report presents precipitation data for the San Francisco Bay region in a form suitable for use as criteria for both drainage design and the study of the stability of land slopes. The data presented include (1) an isohyetal map showing long-term mean annual precipitation and (2) a table of...

The effect of salinity on the temperature-depth relations of a brine of constant composition, enclosed in a vein system, but freely connected to the surface, and everywhere at the boiling point for the hydrostatic head, was calculated by using a mathematical model. The Na-Ca-K-Cl brines...

The relationship between the gravitational and magnetic potentials caused by a uniform distribution of mass and magnetization may be used to obtain independent information about these physical properties. The general relationship in the frequency domain between the Fourier transforms of the gravity and magnetic anomaly...

Continuous magnetic profiles were recorded by a truck-mounted magnetometer along road traverses over stratified metamorphic rocks and plutonic igneous rocks of the New England Appalachians. The records show a series of distinctive, highly detailed magnetic anomalies which closely reflect the nature and distribution of near-surface...

A 140,000 km aeromagnetic and total-count gamma radiometric survey was made over Liberia in 1967-68 along north-south lines spaced 0.8 km over land and 4 km over the continental shelf. The data approximately delineate the boundary between the Liberian (ca. 2700 m.y.) age province in...

Remote sensing of the earth promises to become an operational tool of the engineer and the scientist within the next few years. There are no real technical limits on the uses of data from space sensors. However, it is not practical to fly special missions, particularly in space, for each...

The mourning dove (Zenaidura macroura) call-count survey is a nationwide audio-census of breeding mourning doves. Recent analyses of the call-count routes have utilized a stratification based upon physiographic regions of the United States. An analysis of 5 years of call-count data, based upon stratification using potential natural vegetation, has demonstrated...

During 1970 the Geological Survey conducted a study to evaluate the surface-water data collection program. Objectives were formulated, specific goals were set, a massive analysis of available data was made to determine the extent to which the present system enables the goals to be met, alternatives...

Data are given on the composition, temperature, pressure, and density of the hydrothermal fluids present in the central Cu-Mo core of the deposit at Bingham, Utah, and in its related but not necessarily coeval peripheral Pb-Zn deposits. These data are based on a study of...

Computations of chemical denudation rates (that is, the average rate of lowering of the earth's crust by chemical processes) should be based only upon those components of dissolved loads of streams that are derived from chemical weathering of rocks and soils, even though identification of those components is difficult and...

A complete characterization of natural waters includes a determination of the concentrations of 30 or more minor elements. Emission spectrochemical methods are uniquely suited to the determination of a comparatively large number...

Heat of solution measurements of the enthalpies of Na-K mixing, Al-Si ordering, and fusion for crystalline solutions and end-member phases in the system Na(AlSi3O8)–K(AlSi3O8) were obtained with a vacuum-jacketed, isoperibolic calorimeter using 20.1 percent hydrofluoric acid at temperatures ranging from 40 to 60°C. Heat of solution data for artificially prepared...

Studies of published and unpublished geologic and ground-water data, for an inventory of 6,032 wells and 754 springs in parts of Inyo and Mono Counties, California, and Clark, Esmeralda, Lincoln, and Nye Counties, Nevada, reveal the following information:A complex sequence of granitic, metamorphic, volcanic, and sedimentary rocks of Precambrian to...
