Geology and ore deposits of the Cottonwood-American Fork area, Utah
F. C. Calkins, B. S. Butler, V. C. Heikes
1943, Professional Paper 201
The first systematic geological study of the Wasatch Range was done by the Fortieth Parallel Survey,1 mainly by Clarence King and S. F. Emmons. These pioneers broadly outlined the stratigraphy and distribution of the rocks and. prepared regional geologic maps that for parts of the region have not yet been...
Geology of the Cimarron Range, New Mexico
J.F. Smith Jr. , L.L. Ray
1943, Geological Society of America Bulletin (54) 891-924
In north-central New Mexico the rugged Cimarron Range marks the eastern margin of the Southern Rocky Mountains, abruptly rising more than 5000 feet above the adjacent Great Plains. Structurally the range is a northward-plunging anticline with a core of pre-Cambrian crystalline rocks. Faulting along the eastern and western margins of...
Quartz veins in the Ouachita mountains of Arkansas and Oklahoma (Their relations to structure, metamorphism, and metalliferous deposits)?
Hugh Dinsmore Miser
1943, Economic Geology (38) 91-118
An important chapter of the total geologic history of the Ouachita Mountains is revealed by the quartz veins and crystals. These and the associated minerals are hydrothermal deposits of probable magmatic origin, formed during the closing stage of the mid-Permsylvanian orogeny. The metalliferous deposits of the Ouachita Mountains appear to...
A frequency‐method of evaluating ground‐water levels
Lyman C. Huff
1943, Eos, Transactions, American Geophysical Union (24) 573-580
Water‐levels in wells, which are utilized by the hydrologist as a measure of ground‐water storage, customarily are measured in terms of distance below a convenient measuring point and expressed with reference to a fixed datum. Datum‐planes or surfaces of several types have been used—each serving some particular purpose advantageously. These...
Correlation of ground‐water levels and precipitation on Long Island, New York
C. E. Jacob
1943, Eos, Transactions, American Geophysical Union (24) 564-573
Long Island simulates in a general way an aquifer in the form of an infinite strip confined between parallel boundaries at constant head (sea‐level), over which recharge precipitation is assumedly uniform. The non‐steady flow of water in this idealized system is analyzed assuming provisionally that the effective thickness of saturated...
The Finley Site: Antiquity of the Finley Site
John T. Hack
1943, American Antiquity (8) 235-241
This report is based on two months reconnaissance in the summer of 1941 in the Eden Valley, Wyoming. The work is as yet far from complete and the conclusions presented here must be regarded as tentative. It is hoped that in the future more extensive geological work may be undertaken.The...
A method for determining transmissibility‐ and storage‐coefficients by tests of multiple well‐systems
Leland K. Wenzel, A.L. Greenlee
1943, Eos, Transactions, American Geophysical Union (24) 547-564
Ground‐water has long been recognized as one of our important natural resources, but only in about the last 20 years has concentrated effort been made to place ground‐water hydrology on a quantitative basis. The quantitative approach to ground‐water work has been brought about largely through the leadership of O. E....
Helvite, a product of magmatic emanations at Iron Mountain, Sierra Socorro Counties, New Mexico
Jewell J. Glass
1943, Eos, Transactions, American Geophysical Union (24) 252-257
The recent discovery of the widespread occurrence of helvite, a beryllium‐bearing mineral, at Iron Mountain, New Mexico, has aroused interest in the commercial possibilities of a mineral which heretofore has been considered to have only scientific significance. Helvite contains about 13 per cent beryllium oxide as compared with five to...
Report of Committee on Runoff, 1942–43
W. G. Hoyt, Bertram Barnes, H.B.S. Cooke, E.S. Cullings, G.A. Hathaway, Karl R. Jetter, N.H. Leupold, Phillip Light, C. C. McDonald, F.T. Mavis, L.K. Sherman, Waldo E. Smith, F. Snyder, H.G. Wilm
1943, Eos, Transactions, American Geophysical Union (24) 422-423
The Committee on Runoff was not formally constituted until February 6, 1943, when the members of the Section, as listed above, were asked to serve. At the suggestion of President CHURCH the Committee has been so selected that there is Nation‐wide geographic distribution from West to East with the majority...
Report of Committee on Glaciers, 1942–43
Francois E. Matthes
1943, Eos, Transactions, American Geophysical Union (244) 389-401
The personnel of the Committee at present is as follows:Harry Fielding Reid, Professor Emeritus of Geology, Johns Hopkins University, 608 Cathedral Street, Baltimore, MarylandWilliam H. Hobbs, Professor Emeritus of Geology, University of Michigan, Ann Arbor, Michigan Colonel Lawrence Martin, Chief, Division of Maps, Library of Congress, Washington, D.C.James E. Church,...
The nickel deposits of Yakobi Island, southeastern Alaska
George C. Kennedy
1943, Eos, Transactions, American Geophysical Union (24) 257-257
Some of the large, low‐grade nickel‐copper deposits of Bohemia Basin, Yakobi Island, south‐eastern Alaska, which previously had been mapped and studied by the United States Geological Survey, were explored during parts of 1941 and 1942 by the United States Bureau of Mines. The Gealogical Survey interpreted the geologic features of...
