Occurrence of strontium in the surface and ground waters of Champaign county, Ohio
A.J. Feulner, J.H. Hubble
1960, Economic Geology (55) 176-186
Naturally occurring strontium was found in both surface and ground waters during an investigation of the water resources of Champaign County, Ohio. The strontium is related to the presence of celestite (strontium sulfate) in rocks associated with evaporite deposition. The principal source of celestite in Ohio is in rocks of Late Silurian age. Celestite is present also in the glacial...
Geology and ground-water resources of the island of Kauai, Hawaii
Gordon A. Macdonald, Dan A. Davis, Doak C. Cox
1960, Bulletin 13
Kauai is one of the oldest, and is structurally the most complicated, of the Hawaiian Islands. Like the others, it consists principally of a huge shield volcano, built up from the sea floor by many thousands of thin flows of basaltic lava. The volume of the Kauai shield was on...
Earthquake fluctuations in wells in New Jersey
Charles R. Austin
1960, New Jersey Division of Water Policy and Supply Water Resources Circular 5
New Jersey is fortunate to be situated in a region that is relatively stable, geologically. For this reason scientists believe, on the basis of the best scientific evidence available, that the chances of New Jersey experiencing a major earthquake are very small. The last major earthquake on the east coast...
Factual data for public-supply wells and selected irrigation wells in Monmouth County, New Jersey
Leo A. Jablonski
1960, New Jersey Division of Water Policy and Supply Water Resources Circular 4
The investigation of the ground-water resources of Monmouth County is part of a Statewide water-resources program. This study was made by the U.S. Geological Survey in cooperation with the new Jersey Department of Conservation and Economic Development, Division of Water Policy and Supply. It was under the general direction of...
A geologic-profile plotter
O.T. Marsh
1960, Economic Geology (55) 201-204
Design and uses are described of an easy-to-construct instrument that facilitates construction of profiles of land surfaces, geologic formations, or other features such as profiles of geophysical or geochemical anomalies. Response to data from users of the instrument indicates that it is both faster and more convenient than previous methods. ...
Core logs from five test holes near Kramer, California
William K. Benda, Richard C. Erd, Ward C. Smith
1960, Bulletin 1045-F
In 1957, five test holes were drilled near Kramer, Calif., in the western Mojave Desert, for the U.S. Geological Survey. The drill sites are in topographic basins where gravimetric and geologic surveys indicated the presence, beneath alluvium, of a thick section of Quaternary and Tertiary sedimentary and volcanic rocks.Two holes,...
Equivalent weight of humic acid from peat
A. M. Pommer, Irving A. Breger
1960, Geochimica et Cosmochimica Acta (20) 45-50
By means of discontinuous titration, the equivalent weight of humic acid isolated from a peat was found to increase from 144 to 183 between the third and fifty-second day after the humic acid was dissolved. Infra-red studies showed that the material had probably condensed with loss of carbonyl groups....
A primer on water
Luna Bergere Leopold, Walter Basil Langbein
1960, Report
When you open the faucet you expect water to flow. And you expect it to flow night or day, summer or winter, whether you want to fill a glass or water the lawn. It should be clean and pure, without any odor.You have seen or read about places where the...
The true pikes

A "virus" disease of chinook salmon
A. J. Ross, R.R. Rucker
1960, Fishery Leaflet 497
Epizootics among chinook salmon fingerlings at the Coleman National Fish Hatchery have occurred periodically since 1941. A virus or virus-like filterable agent has been demonstrated to be the causative agent of this disease....
Effect of crystal thickness and geometry on the alpha-particle resolution of CsI (Tl)
P. Martinez, F. E. Senftle
1960, Review of Scientific Instruments (31) 974-977
The resolution of CsI(Tl) for Po210 alpha particles has been measured as a function of crystal thickness. The best resolution of a ½‐in. diam cylindrical crystal was obtained for a thickness of 0.38 mm, and the effect of thickness on the resolution is discussed. Based on the proposed model, a conical crystal...
Diagenesis of metabolites and a discussion of the origin of petroleum hydrocarbons
Irving A. Breger
1960, Geochimica et Cosmochimica Acta (19) 297-308
Proteins and carbohydrates are rapidly degraded to compounds of no direct interest in the problem of the origin of petroleum. Lignin, if carried into marine basins in the form of humic substances, is probably the major progenitor of kerogen rather than the precursor of petroleum. Pigments are but minor contributors...
Potentiometric titration and equivalent weight of humic acid
A. M. Pommer, Irving A. Breger
1960, Geochimica et Cosmochimica Acta (20) 30-44
The “acid nature” of humic acid has been controversial for many years. Some investigators claim that humic acid is a true weak acid, while others feel that its behaviour during potentiometric titration can be accounted for by colloidal adsorption of hydrogen ions. The acid character of humic acid has been...
