Faulting of rocks in three-dimensional strain fields I. Failure of rocks in polyaxial, servo-control experiments
Z. Reches, James H. Dieterich
1983, Tectonophysics (95) 111-132
The dependence of the number of sets of faults and their orientation on the intermediate strain axis is investigated through polyaxial tests, reported here, and theoretical analysis, reported in an accompanying paper. In the experiments, cubic samples of Berea sandstone, Sierra-White and Westerly granites, and Candoro and Solnhofen limestones were...
Separation of arsenic(III) and arsenic(V) in ground waters by ion-exchange
Walter H. Ficklin
1983, Talanta (30) 371-373
The predominant species of arsenic in ground water are probably arsenite and arsenate. These can be separated with a strong anion-exchange resin (Dowex 1 × 8; 100–200 mesh, acetate form) in a 10 cm × 7 mm column. Samples are filtered and acidified with concentrated hydrochloric acid (1 ml per...
An ion-selective electrode method for determination of chlorine in geological materials
P. J. Aruscavage, E.Y. Campbell
1983, Talanta (30) 745-749
A method is presented for the determination of chlorine in geological materials, in which a chloride-selective ion electrode is used after decomposition of the sample with hydrofluoric acid and separation of chlorine in a gas-diffusion cell. Data are presented for 30 geological standard materials. The relative standard deviation of the...
A rapid geochemical spectrophotometric determination of tungsten with dithiol
E. P. Welsch
1983, Talanta (30) 876-878
1-g sample is decomposed with nitric and hydrofluoric acids, and after evaporation of the solution to dryness the residue is dissolved in concentrated hydrochloric acid. A clear aliquot is treated with stannous chloride to inhibit interferences. The blue tungsten dithiol complex is developed at a temperature of 85° over a...
Determination of arsenic in geological materials by x-ray fluorescence spectrometry after solvent extraction and deposition on a filter
A.E. Hubert
1983, Talanta (30) 967-968
Rock, soil, or sediment samples are decomposed with a mixture of nitric and sulphuric adds. After reduction from arsenic(V) with ammonium thiosulphate, arsenic(III) is extracted as the chlorocomplex into benzene from a sulphuric-hydrochloric acid medium. The benzene solution is transferred onto a filter-paper disc impregnated with a solution of sodium...
Hydrology of area 54, northern Great Plains, and Rocky Mountain coal provinces, Colorado and Wyoming
Gerhard Kuhn, P. D. Daddow, G. S. Craig
1983, Open-File Report 83-146
A nationwide need for information characterizing hydrologic conditions in mined and potential mine areas has become paramount with the enactment of the Surface Mining Control and Reclamation Act of 1977. This report, one in a series covering the coal provinces nationwide, presents information thematically by describing single hydrologic topics through...
Petroleum and mineral resources of Antarctica
Karel Kovar
John Charles Behrendt, editor(s)
1983, Circular 909
No known petroleum or mineral resources occur in Antarctica. The data on these subjects have been collected, mainly since the IGY (International Geophysical Year), 1957-58, as a part of other research carried out by geologists and geophysicists from a number of countries. Specific resource-related studies have not been made. Wright...
Assessment of gray whale feeding grounds and sea floor interaction in the northeastern Bering Sea
C.H. Nelson, K.R. Johnson, John H. Barber
1983, Open-File Report 83-727
A dense ampeliscid amphipod community in Chirikov Basin and around St. Lawrence Island in the northeastern Bering Sea has been outlined by summarizing biological studies, analyzing bioturbation in sediment samples, and examining sea floor photos and videotapes. The amphipod population is associated with a homogeneous, relict fine-grained sand body 0.10-1.5...
Estimation of nonpoint sources of phosphorus for lakes in the Puget Sound region, Washington
Robert J. Gilliom
1983, Open-File Report 82-161
Control of eutrophication of lakes in watersheds undergoing development is facilitated by estimates of the amounts of phosphorus (P) that reach the lakes from areas under various types of land use. Using a mass-balance model, the writer calculated P loadings from present-day P concentrations measured in lake water and from...
Computation of continuous records of streamflow
E.J. Kennedy
1983, Techniques of Water-Resources Investigations 03-A13
Records of continuous streamflow, published in the U.S. Geological Survey annual Water Data Reports for the States and territories, are computed from field data, mainly discharge measurements and recorder charts or tapes. This manual describes the computation procedures used and some details of related field operations. It was compiled mostly...
Projected effects of proposed chloride-control projects on shallow ground water– Preliminary results for the Wichita River basin, Texas
Sergio Garza
1983, Water-Resources Investigations Report 83-4026
The U.S. Army Corps of Engineers' plan to control the natural chloride pollution in the Wichita River basin includes the construction of Truscott Brine Lake on a tributary of the North Wichita River. In connection with the proposed brine lake, the U.S. Geological Survey was requested to: (1) Define the...
