Earthquake prediction; fact and fallacy
R.N. Hunter
1976, Earthquake Information Bulletin (USGS) (8) 24-27
Earthquake prediction is a young and growing area in the field of seismology. Only a few years ago, experts in seismology were declaring flatly that it was impossible. Now, some successes have been achieved and more are expected. Within a few years, earthquakes may be predicted as routinely as the...
The zonal distribution of selected elements above the Kalamazoo porphyry copper deposit, San Manuel district, Pinal County, Arizona
M.A. Chaffee
1976, Journal of Geochemical Exploration (5) 145-165
There may be many as-yet-undiscovered porphyry copper deposits that exist as blind deposits deep within exposed rock bodies. The Kalamazoo porphyry copper-molybdenum deposit is a blind deposit present at depths up to at least 1,000 m (about 3,200 ft) that contains zoning features common to many of the known...

Geologic history of Cape Cod, Massachusetts
Water Resources Division, U.S. Geological Survey
1976, Report
Cape Cod, a sandy peninsula built mostly during the Ice Age, juts into the Atlantic Ocean like a crooked arm. Because of its exposed location, Cape Cod was visited by many early explorers. Although clear-cut evidence is lacking, the Vikings may have sighted this land about 1,000 years ago. It...

Lunar nomenclature: A dissenting note
D.W.G. Arthur
1976, Icarus (27) 571-573
This note reviews the nature of the traditional (Mädler) lunar nomenclature and the recent developments based on the use of more than 2000 named provinces. It appears that the new nomenclature is less efficient than the old in many cases and may lead to an impossible publication situation. The unnecessary...
RESIN, a FORTRAN IV program for determining the area of influence of samples or drill holes in resource target search
D.A. Singer
1976, Computers & Geosciences (2) 249-260
A FORTRAN IV program that calculates the area of influence of drill holes or samples with respect to the size and shape of elliptical or circular resource targets is presented. Program options include determination of the degree to which areas within a region have been explored and estimation of probabilities...
Determination of lead in rocks by radiometric isotope dilution and substoichiometric extraction
Philip Aruscavage
1976, Analytica Chimica Acta (82) 343-348
A rapid procedure is described for the determination of lead in rocks by an isotope-dilution substoichiometric method. After the sample has been digested with acid in the presence of 210Pb tracer, the lead is separated by dithizone extractions. After the lead has been back-extracted into aqueous solution, it is reacted with...
Utilization of satellite data for inventorying prairie ponds and lakes
E.A. Work, D.S. Gilmer
1976, Photogrammetric Engineering and Remote Sensing (42) 685-694
By using data acquired by LANDSAT-1 (formerly ERTS- 1), studies were conducted in extracting information necessary for formulating management decisions relating to migratory waterfowl. Management decisions are based in part on an assessment ofhabitat characteristics, specifically numbers, distribution, and quality of ponds and lakes in the prime breeding range. This...
Rapid determination of nanogram amounts of tellurium in silicate rocks
L. P. Greenland, E.Y. Campbell
1976, Analytica Chimica Acta (87) 323-328
A hydride-generation flameless atomic-absorption technique is used to determine as little as 5 ng g-1 tellurium in 0.25 g of silicate rock. After acid decomposition of the sample, tellurium hydride is generated with sodium borohydride and the vapor passed directly to a resistance-heated quartz cell mounted in an atomic-absorption spectrophotometer. Analyses...
Instrumental activation analysis of coal and fly ash with thermal and epithermal neutrons and short-lived nuclides
E. Steinnes, J.J. Rowe
1976, Analytica Chimica Acta (87) 451-462
Instrumental neutron activation analysis is applied to the determination of about 25 elements in coals and fly ash by means of nuclides with half-lives of less than 48 h ; thermal and epithermal irradiations are used. The results indicate that epithermal activation is preferable for twelve of the elements (Ga,...
Concretionary manganese-iron oxides in streams and their usefulness as a sample medium for geochemical prospecting
G.A. Nowlan
1976, Journal of Geochemical Exploration (6) 193-210
Correlation studies of 400 samples of sieved stream sediments and 325 samples of fluvial, concretionary Mn-Fe oxides from Maine resulted in the separation of elements into the following categories: (1) elements not scavenged by Mn-Fe oxides — B, Cr, K, Mg, Rb, Sc, Ti, V, and Zr; (2) elements...
A magnetic method for determining the geometry of hydraulic fractures
J.D. Byerlee, M.J.S. Johnston
1976, Pure and Applied Geophysics PAGEOPH (114) 425-433
We propose a method that may be used to determine the spatial orientation of the fracture plane developed during hydraulic fracture. In the method, magnetic particles are injected into the crack with the fracturing fluid so as to generate a sheet of magnetized material. Since the magnetization of a body...
Distribution of small channels on the Martian surface
D. Pieri
1976, Icarus (27) 25-50
The distribution of small channels on Mars has been mapped from Mariner 9 images, at the 1:5 000 000 scale, by the author. The small channels referred to here are small valleys ranging in width from the resolution limit of the Mariner 9 wide-angle images (???1 km) to about 10...
Avian botulism epizootiology on sewage oxidation ponds in Utah
Daniel W. Moulton, Wayne I. Jensen, Sondra K. Stewart
1976, Journal of Wildlife Management (40) 735-742
In the microenvironment concept of avian botulism epizootiology, it is hypothesized that invertebrate carcasses may serve both as a substrate for toxin production by Clostridium botulinum type C and as a vehicle for toxin transmission to water birds. We field-tested that hypothesis by attempting to induce botulism in wing-clipped mallard...

Production of hybrid, androgenetic, and gynogenetic grass carp and carp
J.G. Stanley
1976, Transactions of the American Fisheries Society (105) 10-16
Hybridization, androgenesis, and gynogenesis were studied as potential methods for creating nonreproducing populations of fish. Hybrids from crosses of female grass carp (Ctenopharyngodon idella) X male carp (Cyprinus carpio, Israeli mirrow variety) died during embryonic development. Hybrids of the reciprocal cross hatched and were stocked in ponds, but most died...

Allantoinase, an enzyme in the purine-urea cycle, was found in Eudistylia vancouveri (Polychaeta). The enzyme had a pH optimum at 7.6. The Km was 0.012 M allantoin, and the Arrhenius energy of activation was 12.6 to 14.6 kcal/mol....

The San Francisco cow; did she or didn’t she?
M. Hill
1976, Earthquake Information Bulletin (USGS) (8) 19-23
No one has suggested that Mr. Shafter's nameless cow was the cause of the 1906 earthquake, but she has been the source of as persistent a rumor as Mrs. Murphy's Chicago cow. Since 1906, "the cow that fell in the crack" has been a favorite subject of humorous speculation. large...
