A geochemical study of oil in metalliferous veins, Idarado Mine, San Juan Mountains, Colorado
Peter M. Gerrild
1976, Journal of Research of the U.S. Geological Survey (4) 593-599
A tarry, benzene-soluble material is present in metal-rich veins in the Idarado mine, Ouray County, Colo., in an area not known to have petroleum resources. The material was compared chemically, spectometrically, and chromatographically with oils from four fields in the nearby Paradox basin. Each of these oil fields contains reservoir...
Rise of a variable-viscosity fluid in a steadily spreading wedge-shaped conduit with accreting walls
Arthur H. Lachenbruch, Manuel Nathenson
1976, Journal of Research of the U.S. Geological Survey (4) 181-188
Relatively rigid plates making up the outer 50 to 100 km of the Earth are steadily separating from one another along narrow globe-circling zones of submarine volcanism, the oceanic spreading centers. Continuity requires that the viscous underlying material rise beneath spreading centers and accrete onto the steadily diverging plates. It...
Geology and geophysics of the southern Raft River Valley geothermal area, Idaho, USA
Paul L. Williams, Don R. Mabey, Adel A. R. Zohdy, Hans D. Ackermann, Donald B. Hoover, Kenneth L. Pierce, Steven S. Oriel
1976, Conference Paper, Proceedings: second United Nations Symposium on the development and use of geothermal resources, San Francisco, California, USA, 20-29 May 1975
The Raft River valley, near the boundary of the Snake River plain with the Basin and Range province, is a north-trending late Cenozoic downwarp bounded by faults on the west, south, and east. Pleistocene alluvium and Miocene-Pliocene tuffaceous sediments, conglomerate, and felsic volcanic rocks aggregate 2 km in thickness. Large...
Beacon Hill end moraine, Boston: new explanation of an important urban feature
Clifford A. Kaye
Donald R. Coates, editor(s)
1976, Book chapter, Urban Gomorphology (Geological Society of America, Special Paper 174)
The usefulness of geology to engineers is in direct proportion to how well it helps us predict the subsurface; these predictions, in turn, depend on our knowledge of the geomorphic processes that molded the terrain. The uncertainties of interpretation are particularly great in glaciated terrain because our understanding of both...
Regional geologic framework off northeastern United States
John Schlee, John C. Behrendt, John A. Grow, James M. Robb, Robert E. Mattick, P. T. Taylor, B. J. Lawson
1976, American Association of Petroleum Geologists Bulletin (60) 926-951
Six multichannel seismic-reflection profiles taken across the Atlantic continental margin off the northeastern United States show an excess of 14 km of presumed Mesozoic and younger sedimentary rocks in the Baltimore Canyon trough and 8 km in the Georges Bank basin.Beneath the continental rise, the sedimentary prism thickness exceeds 7...

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...

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:...
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,...
On the origin of the livingstonite deposits at Huitzuco, Guerrero, Mexico

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...
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...
