K.A. Kvenvolden, E. Roedder
1971, Geochimica et Cosmochimica Acta (35) 1209-1229
Quartz crystals from calcite veins of unknown age in Precambrian metasedimentary rocks at Geiaus No. 6 and Aukam farms in South-West Africa contain both primary and secondary inclusions filled with one or a variable combination of: organic liquid, moderately saline aqueous liquid, dark-colored...

A general evaluation of the frequency distribution of clay and associated minerals in the alluvial soils of Ceylon
J.W. Herath, R.W. Grimshaw
1971, Geoderma (5) 119-130
Clay mineral analyses were made of several alluvial clay materials from Ceylon. These studies show that the soil materials can be divided into 3 clay mineral provinces on the basis of the frequency distribution of...

Tertiary climatic fluctuations and methods of analysis of tertiary floras
J. A. Wolfe
1971, Palaeogeography, Palaeoclimatology, Palaeoecology (9) 27-57
On theoretical grounds, an analysis of the physiognomy of a Tertiary leaf assemblage is more direct and reliable than a circuitous floristic analysis in assigning thermal regimes to fossil assemblages. Using primarily foliar physiognomy and secondarily floristic composition, it can be shown that: (1) some middle latitude Tertiary assemblages probably...
Geysers
1971, Report
A geyser is a special type of hot spring that from time to time spurts water above ground. It differs from most hot springs in having periodic eruptions separated by intervals without flow of water. The temperature of the erupting water is generally nearly at boiling for pure water (212°F...
Uranium-series dating of some pleistocene marine deposits in Southern California
Barney J. Szabo, J. G. Vedder
1971, Earth and Planetary Science Letters (11) 283-290
Analyses of uranium isotopes and their long-lived daughter products showed evidence of uranium migration in most of the 22 fossil mollusk shell samples from marine terrace deposits in southern California. Two samples, however, remained an ideal closed system as indicated by concordant230Th/234U...
Some Pb and Sr isotopic measurements on eclogites from the Roberts Victor mine, South Africa
W.I. Manton, M. Tatsumoto
1971, Earth and Planetary Science Letters (10) 217-226
Five nodules of eclogite, one nodule of garnet peridotite and one sample of kimberlite from the Roberts Victor mine were analyzed for concentrations of U, Th, Pb, Rb and Sr and isotopic compositions of Pb and Sr. In the eclogites, U content...

Population biology of lake trout (Salvelinus namaycush) of Lake Superior before 1950
Gary T. Sakagawa, Richard L. Pycha
1971, Journal of the Fisheries Research Board of Canada (28) 65-71
Scale samples collected in 1948 were used to estimate the instantaneous total mortality rate (0.70) and growth for lake trout (Salvelinus namaycush) in Lake Superior before the population had been significantly reduced by the sea lamprey (Petromyzon marinus). Indirect evidence indicates that the instantaneous natural mortality rate was probably 0.10–0.25....
Calcium-magnesium carbonate solid solutions from Holocene conglomerate cements and travertines in the Coast Range of California
I. Barnes, J. R. O’Neil
1971, Geochimica et Cosmochimica Acta (35) 699-718
Two calcium-magnesium carbonate solid solutions form Holocene travertines and conglomerate cements in fresh water stream channels of the Coast Range of California. Calcite does not yield the {015} diffraction maximum. The {006} diffraction maximum is lacking over most of the range of composition...
Thermoluminescence of Apollo 12 lunar samples
Richard R. Doell, G. Brent Dalrymple
1971, Earth and Planetary Science Letters (10) 357-360
Thermoluminescence (TL) glow curve and decay characteristics of Apollo 12 fines and soil samples are similar to those from Apollo 11. Interpretation of the results from the core sample is difficult because of inadequate sample, spacing, but it appears that the part...

Sampling of fish muscle for M.S.222 and quinaldine residues
Charles W. Luhning, Paul D. Harman
1971, Journal of the Fisheries Research Board of Canada (28) 113-115
Large variations in concentrations of M.S. 222 (tricaine methanesulfonate) and quinaldine (2-methylquinoline) residues occurred in various areas of fish fillets. Residue analyses of replicate samples from homogenized fillets yielded more representative results than samples cut from various areas of fillets....

Aeromagnetic study of the midcontinent gravity high of central United States

A composite map of detailed aeromagnetic surveys over the midcontinent gravity high provides coverage of the 600-mi-long buried belt of mafic rocks of the Keweenawan Series from their outcrop localities in Minnesota and Wisconsin through Iowa and Nebraska. A map of the subsurface extent of the mafic rocks, based on...
Giant American brook lampreys, Lampetra lamottei, in the upper Great Lakes
Patrick J. Manion, Harold A. Purvis
1971, Journal of the Fisheries Research Board of Canada (28) 616-620
Five female American brook lampreys, Lampetra lamottei, collected in lakes Michigan and Huron averaged nearly twice as long and about six times as heavy as American brook lampreys of normal size. Three factors suggested that the giant lampreys may have fed parasitically after metamorphosis: morphological adaptations of the species for parasitic...

A procedure for testing the antigenicity of vaccines for immunization of fish against Furunculosis
Jamieson E. Holway, G.W. Klontz

Furnunculosis, a bacterial disease caused by Aeromonas salmonicida, is potentially one of the most devastating diseases in trout and salmon hatcheries. The disease may be controlled by three methods. The most frequently used method of control has been drug therapy. Unfortunately, the bacteria often develop resistance to the...
