Report of the committee on chemistry of natural waters, 1933–34
C. S. Howard
1934, Eos, Transactions, American Geophysical Union (15) 322-325
The personnel of this Committee during the past year, practically the same as during the previous year, has been as follows: C. S. Howard, Chairman—United States Geological Survey, Washington, D.C. L. C. Case—Gypsy Oil Company, Tulsa, Oklahoma. W. D. Collins—United States Geological Survey, Washington, D.C. H. F. Flynn—United States Engineer Office, 35...
Appendix C—A selected list of papers relating to ground‐water hydrology
A.N. Sayre
1934, Eos, Transactions, American Geophysical Union (15) 318-320
In the following list brief statements have been added to certain references to call attention to special phases of ground‐water problems which are not apparent from the titles. Abstracts of most of these papers have been or will be published in the Annotated Bibliography of Economic Geology. ...
Appendix B—Lake and ground‐water levels
O. E. Meinzer
1934, Eos, Transactions, American Geophysical Union (15) 317-318
An outstanding achievement of the Section of Hydrology has been the work of the Committee on Glaciers in assembling the existing records of the advance and retreat of the glaciers in the Western States and in Alaska, encouraging various agencies in making periodic observations, systematizing and standardizing the work, and...
Status of study of the frequency and magnitude of floods by the Mississippi Valley Committee of the Public Works Administration in collaboration with the United States Geological Survey
Clarence S. Jarvis
1934, Eos, Transactions, American Geophysical Union (15) 420-421
Active work under the recently authorized project relating to floods and their frequencies began in March, and such progress as may be reported at this time is largely that of organization and preliminary planning.One of the outstanding and impressive features of the organization is the provision for cooperative effort, whereby...
Zoning of ore deposits in and adjoining the Leadville District, Colorado
G. F. Loughlin, C. H. Behre Jr.
1934, Economic Geology (29) 215-254
The ore deposits in the heart of the Leadville district, Colorado, are divisible, as shown by Emmons, Irving, and Loughlin,2 into two main classes on the basis of mineral composition: "contact-metamorphic" silicates accompanied by iron oxides, which adjoin an obscure igneous stock, and mixed sulphides accompanied by manganosiderite and quartz gangue, which cut the "contact-metamorphic" deposits and form a...
Structural history of the fracture systems at Grass Valley, California
W. D. Johnston Jr., E. Cloos
1934, Economic Geology (29) 39-54
In the foregoing outline of the structural history of the Grass Valley intrusive the vein fractures are regarded as elements of the internal tectonics of the intrusive body itself. They originated in an early stage of the structural development of the region, and are equivalent to the marginal thrusts observed in the Yose-mite and along the Mother Lode system....
Hawaiian Volcano Observatory record book 1934
1934, Report
The Hawaiian Volcano Observatory (HVO) record books are annual journals in which field observations of eruptive activity at Kīlauea and Mauna Loa volcanoes, on the Island of Hawaiʻi, were compiled by HVO staff for most years from 1912 through early 1966. In addition to descriptive observations, the record books also...
Determination of the common and rare alkalies in mineral analysis
R. C. Wells, R.E. Stevens
1934, Industrial And Engineering Chemistry Analytical Edition (6) 439-442
Methods are described which afford a determination of each member of the alkali group and are successful in dealing with the quantities of the rare alkalies found in rocks and minerals. The procedures are relatively rapid and based chiefly on the use of chloroplatinic acid, absolute alcohol and ether, and...
Some mining districts of eastern Oregon
James Gilluly, J. C. Reed, C. F. Park Jr.
1933, Bulletin 846-A
This report presents the results of a reconnaissance of most of the mining districts of Oregon east of the Cascade Range, with the exception of the districts in the Sumpter quadrangle. The districts described are distributed through an area roughly coincident with the Blue Mountains, which extend over much of...
