Minor-element composition and organic carbon content of marine and nonmarine shales of Late Cretaceous age in the western interior of the United States
H. A. Tourtelot
1964, Geochimica et Cosmochimica Acta (28) 1579-1604
The composition of nonmarine shales of Cretaceous age that contain less than 1 per cent organic carbon is assumed to represent the inherited minor-element composition of clayey sediments delivered to the Cretaceous sea that occupied the western interior region of North America. Differences in minor-element content between these samples and...
Age, growth, sex ratio, and maturity of the whitefish in central Green Bay and adjacent waters of Lake Michigan
Donald Mraz
1964, Fishery Bulletin of the U.S. Fish and Wildlife Service (63) 619-634
This study is based on 1,023 whitefish, Coregonus clupeaformis (Mitchill)--819 in seven samples from five localitites in central Green Bay in 1948-49 and 1851-52 and 204 in a single 1948 collection from northwestern Lake Michigan proper. Records of age indicated unusual strength for only one year class--1943 which strongly dominated...
Studies of pre-Selma Cretaceous core samples from the outcrop area in western Alabama
Watson Hiner Monroe, Richard E. Bergenback, Norman F. Sohl, Esther R. Applin, Estella B. Leopold, Helen M. Pakiser, Louis C. Conant
1964, Bulletin 1160
In 1954 four core holes were drilled in the pre-Selma Cretaceous strata of the Alabama Coastal Plain in order to get unweathered samples within a few miles of the outcrops. During the next few years several specialists studied the cores, and their reports are published as consecutive parts of this...
Crystal formation in furunculosis agar
G. L. Bullock, A. J. Ross
1964, Progressive Fish-Culturist (26) 25-26
SINCE ITS INTRODUCTION SOME MONTHS AGO, FURUNCULOSIS AGAR has been employed in the diagnosis of suspect furunculosis and also as a general purpose medium. During our work with this medium we have noticed discrete "colonies," of crystalline material, which very closely resemble microbial colonies. These crystal colonies are compact and appear...

Origin of high-alumina basalt, andesite, and dacite magmas
W. Hamilton
1964, Science (146) 635-637
The typical volcanic rocks of most island arcs and eugeosynclines, and of some continental environments, are basalt, andesite, and dacite, of high alumina content. The high-alumina basalt differs from tholeiitic basalt primarily in having a greater content of the components of calcic plagioclase. Laboratory data indicate that in the upper...
Submicroscopic spherules and color of tektites
A. N. Thorpe, F. E. Senftle
1964, Geochimica et Cosmochimica Acta (28)
Magnetic susceptibility measurements of 18 tektites from various strewn fields have been made as a function of temperature from 77°K to room temperature. A relatively large temperature-independent component of the magnetic susceptibility was observed in all cases, and an analysis of the data...
Catalytic determination of vanadium in water
M. J. Fishman, M. W. Skougstad
1964, Analytical Chemistry (36) 1643-1646
A kinetic determination of V(V) as a catalyst was spectrophotometrically performed by using the indicator reaction of Gallamine blue (GB+) and bromate at pH 2.0. The reaction was followed by measuring absorbance change for a fixed-time of 3 min at 537 nm. The variables such as reagent...

The earth, Including Its oceans and atmosphere, ls a giant distillation system whose operation brings about the distribution of fresh water throughout the world, from the frozen wastes of polar regions to the burning equatorial deserts. Stated in the simplest terms, distillation, condensation and liquid flow are the elemental processes...

Cenomanian (Cretaceons) Foraminifera from the Puerto Rico Trench
R. Todd, D. Low
1964, Deep-Sea Research and Oceanographic Abstracts (11) 391-393
An assemblage of predominantly planktonic Foraminifera is discussed from rocks of Cenomanian age dredged from between 3,200 and 3,500 fm on the north slope of the Puerto Rico Trench. Thirty-three planktonic and benthonic species are described. Planomalina pulchella is new; nine species are specifically...
Spectrophotometric determination of fluorine in silicate rocks
L. C. Peck, V. C. Smith
1964, Talanta (11) 1343-1347
The rock powder is sintered with a sodium carbonate flux containing zinc oxide and magnesium carbonate, the sinter-cake leached with water and the resulting solution filtered. Fluorine is separated from the acidified filtrate by steam distillation and determined spectrophotometrically by means of a zirconium-SPADNS reagent. If...
Classes of land-surface form in the United States

1964, Report, The national atlas of the United States of America
This digital dataset describes classes of land-surface form in the conterminous United States. The source of the data is the map of land-surface form in the 1970 National Atlas of the United States, pages 62-63, which was adapted from Edwin H. Hammond, "Classes of land surface form in the...
Ground-water data, Sevier Desert, Utah

Potassium-argon and lead-alpha ages of plutonic rocks, Bokan Mountain area, Alaska
M. A. Lanphere, E.M. MacKevett Jr., T. W. Stern
1964, Science (145) 705-707
Most of the granitic rocks in the Bokan Mountain area, southeastern Alaska, are early Paleozoic (probably Ordovician) judged by potassium-argon and lead-alpha age measurements. The Bokan Mountain Granite, the youngest intrusive unit in the area, belongs to a Mesozoic plutonic episode. These age measurements are the first direct evidence for...
Tritium-hydrologic research: Some results of the U.S. Geological Survey Research Program
C.W. Carlston
1964, Science (143) 804-806
In general tritium is of limited usefulness as a tool in hydrologic studies because the tritium content of ground water, as a result of radioactive decay, becomes too low to be detectable after about 50 years. Nevertheless, a unique study was made of the hydrologic cycle of small stream basins...
Numbered nasal discs for waterfowl
James C. Bartonek, C.W. Dane
1964, Journal of Wildlife Management (28) 688-692
Numbered nasal discs were successfully used in studies requiring large numbers of individually marked waterfowl. The procedure for constructing these discs is outlined. Blue-winged teal (Anas discors) with 5/8-inch discs, and canvasback (Aythya valisineria) and redhead (A. americana) with 3/4-inch discs can be individually identified up to 50 and 80...

On the basis of 14,564 spottail shiners (Notropis hudsonius) from Red Lakes, Minnesota, growth rates, strength of year classes, and food utilization were studied. Males and females had different body-scale relationships, and females grew faster than males. There was high correlation between water temperature and growth rate. Strength of year...
