The geology and nickel-copper deposits of Yakobi Island, southeastern Alaska
George C. Kennedy, Matt S. Walton Jr.
1944, Open-File Report 44-85
This report briefly describes the nickel-copper deposits of Yakobi Island, southeastern Alaska, as well as the general geology of the island. It also interprets and summarizes the geological data obtained during drilling tests in 1941 and 1942 by the Bureau of Mines and magnetometer exploration in 1943 by the Geological...
Surface water resources of Iowa for the period October 1, 1940 to September 30, 1942
Lawrence C. Crawford
1944, Water Supply Bulletin 2
The State and Federal cooperative program for the systematic collection of stream-flow records in Iowa was initiated in L914, although a few records were obtained by special arrangements during an earlier period. Since the beginning of the cooperative program measurements of stage or discharge have been obtained at about 100...
Correlation of ground‐water levels and precipitation on Long Island, New York
C. E. Jacob
1944, Eos, Transactions, American Geophysical Union (25) 928-939
A brief though concise statement of the history of ground‐water studies on Long Island, beginning with the early water‐level observations in Brooklyn by STODDARD in 1854, was given by THOMPSON [see 7 of “References” at end of paper]. These and other early data were considered later by LEGGETTE [8]. He...
A graphic procedure in the geochemical interpretation of water‐analyses
A. M. Piper
1944, Eos, Transactions, American Geophysical Union (25) 914-928
This paper outlines certain fundamental principles in a graphic procedure which appears to be an effective tool in segregating analytical data for critical study with respect to sources of the dissolved constituents in waters, modifications in the character of a water as it passes through an area, and related geochemical...
Early history of the Mexican volcano Parícutin
P.D. Trask
1944, Eos, Transactions, American Geophysical Union (25) 617-618
Owing to the good fortune of being stationed near the new volcano Parícutin when it first erupted, I was able to visit it when it was only a week old. As my observations have been recorded in full in a previous article [see 1 of “References” at end of paper],...
Parícutin's cyclic activity
D. E. White
1944, Eos, Transactions, American Geophysical Union (25) 621-628
Parícutin's volcanic activity during its first year of life included a number of periods characterized by flowing lava. The length of time of individual periods ranged from a few days up to more than a month, and were separated by intervals during which little or no lava flowed at the...
Notes on volcanic rocks from Parícutin, Mexico
Charles Milton
1944, Eos, Transactions, American Geophysical Union (25) 618-621
The small collection of lava‐flows, bombs, and ashes from Parícutin, which are to be briefly described, was obtained from several sources and is far from being as completely representative of the volcanic history of the region as one might wish. Until, however, an adequate study is made, these specimens may...
The influence of grain‐selection on the meaning of quartz‐diagrams
Robert E. Fellows
1944, Eos, Transactions, American Geophysical Union (25) 653-659
The most important factor which would reduce confusion in fabric analyses is the expanded use of partial diagrams. The purpose of this paper is to stress the significance of partial diagrams in a consideration of some confusing aspects of petrofabrics.Any statistical study results in the accumulation of a mass of...
Report of Committee on Ground Water, 1943–44
S. W. Lohman, H.F. Blaney, J. Harlan Bretz, Edward Burwell Jr., V.C. Fishel, Willard Gardner, C. S. Howard, G.W. Musgrave, A. M. Piper, N.A. Rose, A.N. Sayre, H.T. Stearns, V. T. Stringfield
1944, Eos, Transactions, American Geophysical Union (25) 712-721
The Chairman extends an apology to G. W. MUSGRAVE for omission of his name from the list of members given in the report of the Committee on Ground Water for 1942–43.The response from members of the Committee in general has been very gratifying and is much appreciated. Four new members,...
Appendix F—Ground‐water studies in Central America
A.N. Sayre
1944, Eos, Transactions, American Geophysical Union (25) 724-725
In June, 1943, the United States Geological Survey assigned two ground‐water geologists, A. N. SAYRE and G. C. TAYLOR, Jr., to study water‐supply problems in Central America for the Coordinator of Inter‐American Affairs and to make recommendations for remedial measures to provide water for cities and towns, especially along the...
Appendix B—The work of the United States Geological Survey and cooperating agencies on ground water for war purposes
O. E. Meinzer
1944, Eos, Transactions, American Geophysical Union (25) 722-723
A report by O. E. MEINZER, published as Appendix B of the annual report of the Committee for 1942–43 [Trans. Amer. Geophys. Union, Part II, pp. 418–420, 1943], describes in some detail the previous work of the United States Geological Survey and cooperating agencies on ground water for war purposes.The...
Appendix A—Progress report of the subcommittee on permeability
Walter B. Langbein
1944, Eos, Transactions, American Geophysical Union (25) 721-722
A variety of units and names of units relating to permeability have been used and are being used by different investigators. This Sub‐Committee was recently organized to provide an open forum for persons of different background and experience to present their views in an orderly manner. Thirteen members representing diverse...
Differences in basin‐characteristics as reflected by precipitation‐runoff relations in San Bernardino and Eastern San Gabriel Mountain drainages
H.M. Stafford, H.C. Troxell
1944, Eos, Transactions, American Geophysical Union (25) 21-35
In interpretation and use of basic hydrological data as basis for planning any public works for conservation or control of water, there is great need for a careful and thorough analysis of the precipitation‐runoff relations. Moreover, when such relations may have been worked out for one particular basin, experience has...
The differentiation of magnesite from dolomite in concentrates and tailings
George T. Faust
1944, Economic Geology (39) 142-151
A new method is presented here for differentiating magnesite from dolomite in crushed materials. This method is based on the essentially different temperatures at which these minerals undergo thermal decomposition. The resulting lowly birefringent periclase is easily distinguished microscopically from the highly birefringent dolomite. This method is based on the...
The fluorspar deposits of Saint Lawrence, Newfoundland
Ralph Erskine Van Alstine
1944, Economic Geology (39) 109-132
Fluorspar from Newfoundland, eighth ranking producer of the world, comes entirely from the St. Lawrence district. Here pre-Cambrian lavas and pyroclastics, Cambrian sedimentary rocks, Ordovician (?) volcanic and sedimentary rocks, and a Paleozoic alaskite-granite comprise the bedrock.Epithermal fluorite veins occupy steeply dipping fault fissures in granite, rhyolite porphyry, and lamprophyre....
"Ribbon rock", an unusual beryllium-bearing tactite
R. H. Jahns
1944, Economic Geology (39) 173-205
The beryllium deposits at Iron Mountain, near the northern end of the Sierra Cuchillo in Sierra and Socorro Counties, New Mexico, are unusual products of contact metamorphism. They occur in irregular bodies of tactile formed by replacement of Paleozoic limestone, generally at or near contacts with small intrusive masses of...
Celestite in Buffalo Cove, Fentress County, Tennessee
T. L. Kesler
1944, Economic Geology (39) 287-306
Mineral aggregates consisting of celestite, dolomite, calcite, and very small amounts of sphalerite, anhydrite, and pyrite occur in the uppermost beds of the Glen Dean limestone, of upper Mississippian age, which crops out along the slopes of Buffalo Cove. Proportions of minerals range widely in adjacent aggregates; maximum content of...
