Review of the stratigraphy and structure of the Gubik anticline
William A. Fischer, Allan N. Kover
1950, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 37
At the direction of Ralph L. Miller, a special study was made of part of the Gubik anticline east of the Colville River. The purpose of this study was two fold; first, the examine the field evidence bearing on east plunge, second, to attempt to establish the continuity of the...
Alteration and metallization in the Bagdad porphyry copper deposit, Arizona
Charles Anderson
1950, Economic Geology (45) 609-628
The porphyritic to seriate-textured quartz monzonite host-rock at Bagdad was changed by hypogene alteration to a granular rock in which the plagioclase became albitic, orthoclase and quartz increased in amount, and hornblende and book-biotite were recrystallized to pale brown leafy biotite. Hypogene sulfides, pyrite and chalcopyrite, were added during the...
Discussion of “Annual floods and the partial duration flood series”
Ven Te Chow, W. B. Langbein
1950, Eos, Transactions, American Geophysical Union (31) 393-941
The writer is interested in finding from this paper a similar idea which he had in mind when engaging in a statistical study of hydrologic data, a part of the Highway Drainage Research Project being carried out in the Department of Civil Engineering, the University of Illinois. However, a complete...
Characteristics of marine uranium-bearing sedimentary rocks
Vincent E. McKelvey, John Marshall Nelson
1950, Economic Geology (45) 35-53
Many marine sedimentary black shale and phosphorite formations contain 0.01 to 0.02 percent uranium, and one, the alum shale of Sweden, contains as much as 0.5 percent. The published fact that uranium is already being recovered on a laboratory scale from Swedish deposits forcefully suggests that similar deposits in the...
Uranium in pegmatites
Lincoln R. Page
1950, Economic Geology (45) 12-34
Uranium and rare-earth minerals are common accessory minerals in pegmatite deposits. No domestic pegmatites have been found that are rich enough to support an economic mining operation for uranium alone; however, small quantities of uranium minerals may be recovered as by-products of feldspar or mica mining. Madagascar is the only...
Uranium-bearing sandstone deposits of the Colorado Plateau
Richard Philip Fischer
1950, Economic Geology (45) 1-11
The uranium-bearing sandstone deposits of the Colorado Plateau are commonly referred to as "carnotite deposits." They have been the principal domestic source of uranium, radium, and vanadium. The deposits are largely restricted to a few stratigraphic zones, along which they have a wide but spotty areal distribution. The ore minerals...
An occurrence of saline ground water on Guadalcanal
R. C. Baker
1950, Eos, Transactions, American Geophysical Union (31) 58-60
Guadalcanal Island is largely mountainous, but on the north side there is a coastal plain about 40 mi long which averages eight miles in width and stands a about 15 ft above sea level. This plain is composed of the coalesced deltas of several large rivers. Most of the military...
Geochemistry of ground water
John David Hem
1950, Economic Geology (45) 72-81
The science of geochemistry is the study of the chemical composition of and actual or possible chemical changes in the crust of the earth. The subdivision of geochemistry concerned with ground water includes study of the nature and amounts of dissolved mineral matter in ground waters, the chemical and geologic...

Activity Of Paricutin Volcano From August 1, 1948 to June 30, 1949
Carl Fries Jr., Celedonio Gutierrez
1950, Eos, Transactions, American Geophysical Union (31) 406-418
The present brief summary of activity at Paricutin Volcano, State of Michoacán, Mexico, follows the pattern of the last report on this volcano published in these Transactions late in 1948 [Wilcox and Gutierrez, 1948]. Anticipating the end of his two‐year period of observation at Parícutin in December 1948, Wilcox instructed the junior...
Discussion of “The relation of geology to dry weather stream flow in Ohio”
William Perry Cross
1950, Eos, Transactions, American Geophysical Union (31) 473-474
The concepts presented in this paper are of great value to the ground‐water hydrologist. They indicate one way to analyze and conveniently use the vast accumulation of stream‐flow records collected by governmental agencies as a tool for geophysical reconnaisance. To be usable as a method of geophysical prospecting for ground...
Activity of Paricutin Volcano from July 1 to December 31, 1949
Carl Fries Jr., Celedonio Gutierrez
1950, Eos, Transactions, American Geophysical Union (31) 732-740
The activity of Parícutin Volcano, State of Michoacan, Mexico, during the second half of 1949 is represented diagrammatically in Figures 1, 2, and 3. An explanatory discussion of these diagrams of eruptive characteristics and a description of the lettered noise types shown on them appeared in an earlier report on...
Report of the Committee on Runoff, 1949–1950
C. C. McDonald
1950, Eos, Transactions, American Geophysical Union (31) 930-934
The Weather Bureau activities in the runoff field during the 1949–1950 year centered largely around its flood and water supply forecasting activities. A new River Forecast Center was inaugurated at Portland, Oregon in January, 1950 to provide service for the Columbia River Basin and adjacent coastal areas. The first custom‐made...
Ground-water problems in the Philadelphia area [Pennsylvania]
Jack B. Graham
1950, Economic Geology (45) 210-221
Large quantities of ground water are used by the Philadelphia Naval Base and many industries in south Philadelphia, as well as by municipalities near Philadelphia in both Pennsylvania and New Jersey.The areal contact between unconsolidated sand, gravel, and clay strata of the Atlantic Coastal Plain and consolidated rocks of the...
Summary of Kinoshita's kuroko deposits of Japan
John J. Collins
1950, Economic Geology (45) 363-376
Summarized translation of a report by Kameki Kinoshita, published in Japanese in 1943, on kuroko deposits (black ore deposits) of Japan. "Kuroko means two things. One is the common mixture of sphalerite, galena, and barite which is ordinarily black to grayish white, depending on the proportion of barite. The other...
Effects of earthquakes, trains tides, winds, and atmospheric pressure changes on water in the geologic formations of southern Florida
Garald G. Parker, Victor Timothy Stringfield
1950, Economic Geology (45) 441-460
Determination of such fundamental hydrologic factors as the coefficients of permeability, transmissibility, and storage; areas of recharge and discharge; direction of ground-water movement; the safe yield; and other pertinent, related factors are based in part upon water-level measurements in wells. But these water-level readings, if not properly understood or weighted,...
Dispersion of copper from the San Manuel copper deposit, Pinal County, Arizona
T. S. Lovering, Lyman C. Huff, H. Almond
1950, Economic Geology (45) 493-514
At San Manuel, near Tucson, Arizona, recent churn drilling has blocked out large reserves of low-grade "porphyry copper" ore. This virgin deposit has a small outcrop and seems ideally suited for a geochemical study of the dispersion pattern produced by weathering in a desert climate. Samples of soils, alluvium, ground...
The appraisal of ore reserves at a Japanese copper mine
John J. Collins
1950, Economic Geology (45) 568-573
Estimates of ore reserves at major Japanese metal mines seem, at first glance, to be readily understandable to American engineers and geologists. Close scrutiny, however, generally reveals unexpected features at each mine. For example, the Hitachi copper mine formerly segregated its developed ore reserve into positive and probable on the...

Esther R. Applin, Louise Jordan
1950, Journal of Paleontology (24) 474-478
This paper discusses changes made in the names of three foraminiferal species originally described by the writers, with particular emphasis on "Lockhartia" cushmani Applin and Jordan. The internal characters of this form are fully described and compared with the diagnostic characteristics of the genus Lockhartia Davies and with the geno-lectotype...
