Stratiform tourmalinites in metamorphic terranes and their geologic significance
J. F. Slack, N. Herriman, R.G. Barnes, I.R. Plimer
1984, Geology (12) 713-716
Stratiform tourmalinites are significant minor rock types in many regional metamorphic terranes of the world. Tourmalinites are more widespread than previously recognized and are especially common in Proterozoic and early Paleozoic sequences dominated by clastic metasedimentary rocks. They consist of conformable layers made...
Evaporation from flowing channels
J.M. Fulford, T.W. Sturm
1984, Journal of Energy Engineering - ASCE (110) 1-9
Stability‐dependent and Dalton‐type mass transfer formulas are determined from experimental evaporation data in ambient and heated channels and are shown to have similar performance in prediction of evaporation. The formulas developed are compared with those proposed by other investigators for lakes and flowing channels. The evaporation data were obtained from...
MULTISPECTRAL REMOTE SENSING OF CARBONATE ROCKS IN THE CONFUSION RANGE, UTAH.
James K. Crowley
1984, Conference Paper
Multispectral imagery recorded by the NASA/Bendix 24-channel aircraft scanner over the Confusion Range, Utah, proved to be extremely sensitive to lithologic variations in exposed carbonate rocks. Major carbonate units within a 16-km**2 study area were readily distinguished, and some aspects of their structure and stratigraphy could be inferred from image...

Evolution of the yardangs at Rogers Lake, California
A. W. Ward, R. Greeley
1984, Geological Society of America Bulletin (95) 829-837
Yardangs are streamlined, wind-eroded hills common to most deserts. Yardangs at Rogers Lake, Mojave Desert, California, have streamlined forms characteristic of objects eroded by moving fluids, a teardrop shape that approaches an ideal 1:4 width-to-length ratio. In wind-tunnel simulations, miniature forms of various...
U. S. GEOLOGICAL SURVEY ALASKAN GOLD PROJECT.
John C. Antweiler, John Cathrall, Richard Tripp
1984, Conference Paper, University of Alaska, Mineral Industry Research Laboratory, MIRL Report
The United States Geological Survey has begun a state-wide study of Alaskan gold deposits. The immediate goals are to determine the relationship of gold in placer deposits to possible primary sources, to determine how nuggets form, to contribute to existing knowledge of principles for prospecting for placer deposits, and determine...

Computation of free oscillations of the earth
Raymond P. Buland, F. Gilbert
1984, Journal of Computational Physics (54) 95-114
Although free oscillations of the Earth may be computed by many different methods, numerous practical considerations have led us to use a Rayleigh-Ritz formulation with piecewise cubic Hermite spline basis functions. By treating the resulting banded matrix equation as a generalized algebraic eigenvalue problem, we are able to achieve great...
On the treatment of evapotranspiration, soil moisture accounting, and aquifer recharge in monthly water balance models
William M. Alley
1984, Water Resources Research (20) 1137-1149
Several two- to six-parameter regional water balance models are examined by using 50-year records of monthly streamflow at 10 sites in New Jersey. These models include variants of the Thornthwaite-Mather model, the Palmer model, and the more recent Thomas abcd model. Prediction errors are relatively similar among the models. However, simulated values...
Determination of uranium concentration in water by liquid anion exchange-delayed neutron analysis
R. A. Zielinski, D. M. McKown
1984, Journal of Radioanalytical and Nuclear Chemistry (84) 207-212
Dissolved uranium is selectively removed from 11 of filtered, acidified water using a liquid anion exchange resin (Amberlite LA-1) dissolved in 10 ml of purified kerosene. The organic phase is then analyzed by a standard delayed neutron counting technique. Yields of removed uranium are consistently greater than 90 percent over...
The complex variable boundary element method: Applications in determining approximative boundaries
T. V. Hromadka II
1984, Engineering Analysis (1) 218-222
The complex variable boundary element method (CVBEM) is used to determine approximation functions for boundary value problems of the Laplace equation such as occurs in potential theory. By determining an approximative boundary upon which the CVBEM approximator matches the desired constant (level curves) boundary conditions, the CVBEM is found to...
Radioisotope dilution analyses of geological samples using 236U and 229Th
J.N. Rosholt
1984, Nuclear Instruments and Methods In Physics Research (223) 572-576
The use of 236U and 229Th in alpha spectrometric measurements has some advantages over the use of other tracers and measurement techniques in isotope dilution analyses of most geological samples. The advantages are: (1) these isotopes do not occur in terrestrial rocks, (2) they have negligible decay losses because of...

The occurrence and behavior of radium in saline formation water of the U.S. Gulf Coast region
T. F. Kraemer, D.F. Reid
1984, Chemical Geology (46) 153-174
Radium has been measured in deep saline formation waters produced from a variety of U.S. Gulf Coast subsurface environments, including oil reservoirs, gas reservoirs and water-producing geopressured aquifers. A strong positive correlation has been found between formation-water salinity and Ra activity, resulting from the interaction of formation water with aquifer...
Analysis of trace metals in water by inductively coupled plasma emission spectrometry using sodium dibenzyldithiocarbamate for preconcentration
C. L. Smith, Jerry M. Motooka, W. R. Willson
1984, Analytical Letters (17) 1715-1730
Since concentrations of trace elements in most natural waters seldom exceed the μg/L level, analysis of trace elements in natural waters by inductively coupled plasma emission spectrometry (ICP) requires a preconcentration procedure. The elements Ag, Bi, Cd, Co, Cu, Fe, Mo, Ni, Pb, Sn, V, W, and Zn were separated...
Graphite sample preparation for AMS in a high pressure and temperature press
M. Rubin, B.O. Mysen, H. Polach
1984, Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms (5) 272-273
A high pressure-high temperature press is used to make target material for accelerator mass spectrometry. Graphite was produced from typical 14C samples including oxalic acid and carbonates. Beam strength of 12C was generally adequate, but random radioactive contamination by 14C made age measurements impractical. ?? 1984....
Spectral properties of ice‐particulate mixtures and implications for remote sensing: 1. Intimate mixtures
Roger N. Clark, Paul G. Lucey
1984, Journal of Geophysical Research: Solid Earth (89) 6341-6348
The spectral properties of water ice-particulate mixtures are studied for the purpose of deriving the ice and particulate abundances from remotely obtained spectra (particulates referring to nonicy materials in the form of grains). Reflectance levels and ice absorption band depths are a complex function of the single scattering albedo of...

The U. S. Geological Survey National Mapping Division (NMD) has been conducting research and development in digital cartography since the early seventies. Since 1977 there has been an acceleration of activities associated with establishing a National Digital Cartographic Data Base (NDCDB). The NMD Office of Research is primarily responsible for...
Oldest (Early Tertiary) subsurface carbonate rocks of St. Croix, USVI, revealed in a turbidite-mudball.
B. H. Lidz
1984, Journal of Foraminiferal Research (14) 213-227
Ranging in age from early Eocene to early Miocene and younger, pelagic foraminifers form the major component of a phenoclastic mudball within a fossiliferous turbidite. The turibidite is part of a more than 12m-thick section of biogenic deposits of middle Miocene age.-from Author...
