Summary of the research work of the Trace Elements Section, Geochemistry and Petrology Branch, for the period April 1, 1948-December 31, 1950
John C. Rabbitt
1951, Trace Elements Investigations 148-A
This report summarizes the research work of the Trace Elements Section, Geochemistry and Petrology Branch, from the organization of the Section in April 1948 to December 31, 1950. The research undertaken thus far consists of laboratory and related field studies in the following fields: 1. Mineralogic and petrologic investigations of radioactive...
Discussion of “a comparison of several heat and mass transfer networks of interest in water conservation”
Ernest R. Anderson, J. J. Marciano, G. E. Harbeck Jr., H. F. Poppendiek, M. Tribus
1951, Eos, Transactions, American Geophysical Union (32) 931-932
The use of electrical networks to describe heat‐ and mass‐transfer problems is an interesting concept and undoubtedly will be of considerable value in future water‐loss investigations, provided the processes involved can be represented, electrically, with sufficient accuracy.Although it is true that errors in measurement of water‐surface temperature may arise when...
List of current and planned projects of the trace elements program, U.S. Geological Survey
Rollin C. Vickers (compiler)
1951, Trace Elements Investigations 201
This summary lists the Geological Survey's current and future investigations of uranium and other elements of related interest. The titles of the investigations are grouped under the headings listed in the table of contents. Entries in each category are listed alphabetically, according to author or project leader, and numbered consecutively....
Geology of the Cedar Hills, Utah
S.L. Schoff
1951, Geological Society of America Bulletin (62)-619
The Cedar Hills, an area of about 320 square miles in central Utah between the northern end of the Wasatch Plateau and the southern end of the Wasatch Mountains, form the boundary zone between the Colorado plateaus and the Great Basin. The oldest exposed rocks are Carboniferous, but most of...
Preliminary report on the stratigraphy and structure of the Shaviovik and upper Sagavanirktok Rivers area, Alaska
A. Samuel Keller, Robert L. Detterman
1951, Geological Investigations, Naval Petroleum Reserve No. 4, Alaska 36
During the 1951 field season, U. S. Geological Survey Navy Oil Unit party 1 conducted stratigraphic and structural studies of the rocks in the area between the westernmost fork of the Shaviovik River and the East Kuparuk River. This area is drained by the Sagavanirktok River and its major tributaries;...
Geologic guides to prospecting for carnotite deposits on the Colorado Plateau
Doris H. Blackman Weir
1951, Trace Elements Investigations 119
This report describes the geologic features that can be used to appraise the favorability of ground in guiding diamond-drill exploration for carnotite deposits in the Upper Jurassic Morrison formation on the Colorado Plateau. It is based on a statistical study of the geologic logs of about 2,500 holes drilled...
Older Precambrian structure in Arizona
Charles A. Anderson
1951, Geological Society of America Bulletin (62) 1331-1346
The older Precambrian rocks of Arizona include the Vishnu, Yavapai, and Pinal schists, all overlain unconformably by nonmetamorphosed younger Precambrian rocks. The older Precambrian schists, unnamed gneisses, and associated granitic masses crop out in many of the mountain ranges southwest of the Colorado plateau. The stratigraphy and structure of the schists can be unraveled to some extent by detailed mapping, and work now in progress by...
Geologic history of sea water: An attempt to state the problem
William W. Rubey
1951, Geological Society of America Bulletin (62) 1111-1148
Paleontology and biochemistry together may yield fairly definite information, eventually, about the paleochemistry of sea water and atmosphere. Several less conclusive lines of evidence now available suggest that the composition of both sea water and atmosphere may have varied somewhat during the past; but the geologic record indicates that these...
Report of the Committee on Ground Water, 1949–1950
S.W. Lohman
1951, Eos, Transactions, American Geophysical Union (32) 769-772
The present report concludes the duties of the above Committee, and the Chairman takes this opportunity to thank the members and others for their splendid cooperation during the triennium ended June 30, 1950. Another in the series of reports on hydrology and physiography of limestone terranes, by A. C. Swinnerton, is given as...
