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.L. Cook, 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...
Flowage and recrystallization in paleozoic quartzites
Robert E. Fellows
1943, Eos, Transactions, American Geophysical Union (24) 271-271
The lower limit of visible traces of penetrative movement in quartz‐rich rocks can be defined by studies of orientations and mutual relations of grains. Intensity of deformation in the central Appalachians decreases gradually from the crystalline Piedmont toward the north, northwest, and west perpendicular to the regional trend. The author...
The manganese oxide minerals, a preliminary report
Michael Fleischer, W.E. Richmond
1943, Economic Geology (38) 269-286
This paper summarizes the results obtained thus far in an intensive study of the manganese oxide minerals. X-ray powder photographs, supplemented by chemical tests, have proved to be the best means for identifying these minerals. Formulas are suggested. Physical properties and X-ray data are listed for the commoner minerals and...
Structural determinations from diamond drilling
John Beaver Mertie
1943, Economic Geology (38) 298-312
Several problems may arise in the geometrical determinations of strike and dip from core drilling. If the stratigraphic or structural surfaces are plane, as the bedding planes of a homocline, two problems may exist, depending upon whether the drill cores do or do not penetrate to some recognizable horizon. The...
