Publication Extents

Not all publications have extents, not all extents are completely accurate
National Cartographic Information Center Newsletter No. 4
Water Resources Division, U.S. Geological Survey
1976, Newsletter 4
Last week, the editor of this publication was told to start signing the introduction. Something to do with credit given for work done. We look at it in the unfortunate light of accountability; our days under the bushel of anonymity are over. Speaking of accountability, it's about time we gave...
United States Geological Survey Annual Report, Fiscal Year 1975
Water Resources Division, U.S. Geological Survey
1976, Report
The Survey resumes the practice of annually summarizing the progress it has made in identifying the Nation's land, water, energy, and mineral resources, classifying federally owned mineral lands and waterpower sites, and in supervising the exploration and development of energy and mineral resources on Federal and Indian lands. The Annual...
Chart of conversion factors: From English to metric system and metric to English system
Water Resources Division, U.S. Geological Survey
1976, Report
The conversion factors in the following tables are for conversion of our customary (English) units of measurement to SI*units, and for convenience, reciprocals are shown for converting SI units back to the English system. The first table contains rule-of-thumb figures, useful for "getting the feel" of SI units or mental...
Man against volcano: The eruption on Heimaey, Vestmann Islands, Iceland
R.S. Williams Jr., J.G. Moore
1976, Report
The U.S. Geological Survey carries out scientific studies in the geological, hydrological, and cartographic sciences generally within the 50 states, but also in cooperation with scientific organizations in many foreign countries for the investigation of unusual earth science phenomena throughout the world. The following material discusses the impact of the...
Nature . . . an environmental yardstick
William T. Pecora
1976, Information and Technology Report 72-21
To one who has spent his professional career in geologic science, conservation always has had special meaning. In the measurements so necessary to his work the geologist develops an integrity in the use of numbers and in the qualifications attending the validity of numbers. Scientific analysis of geologic events and...
On the origin of the livingstonite deposits at Huitzuco, Guerrero, Mexico
G. Tunell, R. E. Learned, E.F. Lawrence
1976, Mineralium Deposita (11) 71-82
Livingstonite is the principal ore mineral in the deposits of the Huitzuco District in the State of Guerrero, Mexico. The ore is found in the lower part of the Morelos Formation, which consists of a thick bed of sedimentary anhydrite containing lenses of dolomite and dolomite breccia. In the unweathered...
Volcanic rocks and processes of the Mid-Atlantic Ridge rift valley near 36 ° 49′ N
R. Hekinian, J.G. Moore, W.B. Bryan
1976, Contributions to Mineralogy and Petrology (58) 83-110
Eighty samples of submarine basaltic lava were sampled from an 8 km segment of the floor and walls of the inner rift valley of the Mid-Atlantic Ridge during the French American Mid-Ocean Undersea Study (project Famous). The samples were collected from outcrops and talus slopes by the three submersibles:...
Strontium isotopic geochemistry of the volcanic rocks and associated megacrysts and inclusions from Ross Island and vicinity, Antarctica
J. S. Stuckless, R.L. Ericksen
1976, Contributions to Mineralogy and Petrology (58) 111-126
Twelve whole-rock samples of volcanic rocks and a composite of 11 basanitoid samples from Ross Island and vicinity, Antarctica show a narrow range of 87Sr/86Sr ratios from 0.70305 to 0.70339. This range is consistent with a model of differentiation from a single parent magma, but the data allow a 30% variation in...
Equilibrium-disequilibrium relations in the Monte Rosa Granite, Western Alps: Petrological, Rb-Sr and stable isotope data
M. Frey, J.C. Hunziker, J. R. O’Neil, H.W. Schwander
1976, Contributions to Mineralogy and Petrology (55) 147-179
Nine samples from the Monte Rosa Granite have been investigated by microscopic, X-ray, wet chemical, electron microprobe, stable isotope and Rb-Sr and K-Ar methods. Two mineral assemblages have been distinguished by optical methods and dated as Permian and mid-Tertiary by means of Rb-Sr age determinations. The Permian assemblage comprises quartz,...
Leasing policies for the extractive resources
E. D. Attanasi, S.R. Johnson
1976, The Annals of Regional Science (10) 36-49
Much of the available analysis of policies for the disposal of publicly held resources is based on comparatively straightforward extensions of the neoclassical pricing and allocation theory. As such, these analyses have to a large extent not fully incorporated the fact that firms normally acquire rights...
Relative influence upon microwave emissivity of fine-scale stratigraphy, internal scattering, and dielectric properties
A. W. England
1976, Pure and Applied Geophysics PAGEOPH (114) 287-299
The microwave emissivity of relatively low-loss media such as snow, ice, frozen ground, and lunar soil is strongly influenced by fine-scale layering and by internal scattering. Radiometric data, however, are commonly interpreted using a model of emission from a homogeneous, dielectric halfspace whose emissivity derives exclusively...
Serpentinization and alteration in an olivine cumulate from the Stillwater Complex, Southwestern Montana
N.J. Page
1976, Contributions to Mineralogy and Petrology (54) 127-137
Some of the olivine cumulates of the Ultramafic zone of the Stillwater Complex, Montana, are progressively altered to serpentine minerals and thompsonite. Lizardite and chrysotile developed in the cumulus olivine and postcumulus pyroxenes; thompsonite developed in postcumulus plagioclase. The detailed mineralogy, petrology, and chemistry indicate that...
On simultaneous tilt and creep observations on the San Andreas Fault
M.J.S. Johnston, S. McHugh, S. Burford
1976, Nature (260) 691-693
THE installation of an array of tiltmeters along the San Andreas Fault1 has provided an excellent opportunity to study the amplitude and spatial scale of the tilt fields associated with fault creep. We report here preliminary results from, and some implications of, a search for interrelated surface...
Problems in shallow land disposal of solid low-level radioactive waste in the united states
P. R. Stevens, G.D. DeBuchananne
1976, Bulletin of the International Association of Engineering Geology (13) 161-171
Disposal of solid low-level wastes containing radionuclides by burial in shallow trenches was initiated during World War II at several sites as a method of protecting personnel from radiation and isolating the radionuclides from the hydrosphere and biosphere. Today, there are 11 principal shallow-land burial sites in the United States...
