Stratigraphic and geotectonic relationships in northern Vermont and southern Quebec
W.M. Cady
1960, Economic Geology (71) 531-576
Stratified rocks of early and middle Paleozoic age form a belt of northeast-trending anticlinoria and synclinoria of middle Paleozoic age, in northern Vermont and adjacent parts of southern Quebec. The foreland margin of this belt, in the Champlain and St. Lawrence valleys to the west, is cut by eastward-dipping thrust faults of...
Geobotanical map of the U.S.S.R.
V.B. Sochava
1960, International Geology Review (2) 311-321
A newly compiled geobotanical map of the U.S.S.R. scale 1:4,000,000 is described. Two hundred and ten categories of vegetation are mapped, classified under 15 major groups. The relation of the mapped vegetation units to climate, soil, ground condition (permafrost), watersheds, and major geomorphic features is emphasized....
Part I, the development of the method
I. Friedman, R. Smith
1960, American Antiquity (25) 476-493
A freshly exposed surface of obsidian will take up water from the atmosphere to form a hydrated surface layer. This layer has a different density and refractive index than does the remainder of the obsidian. Using special techniques, a thin section of the obsidian cut at right angles to the...
Ground-water hydrology and glacial geology of the Kalamazoo area, Michigan
Morris Deutsch, K.E. Vanlier, P.R. Giroux
1960, Progress Report 23
The Kalamazoo report area includes about 150 square miles of Kalamazoo County, Mich. The area is principally one of industry and commerce, although agriculture also is of considerable importance. It has a moderate and humid climate and lies within the Lake Michigan “snow belt”. Precipitation averages about 35 inches per...
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. ...
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....
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,...
