Reconnaissance of radioactive rocks of Massachusetts
Donald H. Johnson
1951, Trace Elements Investigations 69
During the 1948 and 1949 field seasons radiometric car traverses were made along the numbered federal and state highways and along many unnumbered roads of Massachusetts. Near Worcester pegmatitic rocks are estimated to contain about 250 pounds of uranium and 8,500 pounds of thoria per foot of depth. Near Southbridge pegmatitic rocks are...
Reconnaissance of radioactive rocks of Maine
John M. Nelson, Perry F. Narten
1951, Trace Elements Investigations 68
The state of Maine was traversed with car-mounted Geiger-Mueller equipment in the late summer of 1948 and the radioactivity of approximately 4,600 miles of road was logged. All samples were analyzed, both in the field by comparing the radioactivity of each sample to the radioactivity of a stranded measured with a...
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...
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....
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...
Summary of the research work of the Trace Elements Section, Geochemistry and Petrology Branch, for the period January 1-March 31, 1951
John C. Rabbitt
1951, Trace Elements Investigations 151
This report summarized the research work of the Trace Elements Section, Geochemistry and Petrology Branch for the period January 1 - March 31, 1951. Work before that is summarized in an earlier report, "Summary of the research work of the Trace Elements Section, Geochemistry and Petrology Branch, for the period...
Stratigraphic sections of the Phosphoria formation in Idaho, 1947-48, Part III
F.W. O’Malley, D.F. Davidson, R.A. Hoppin, R.P. Sheldon
1951, Trace Elements Investigations 188
.The U.S. Geological Survey has measured and sampled the Phosphoria formation at many localities in Idaho and other western states. These data will not be fully synthesized and analyzed for several years but segments of the data, accompanied by little or no interpretation, are published as preliminary reports as they...
The quantitative determination of calcite associated with the carbonate-bearing apatites
Sol R. Silverman, Ruth K. Fuyat, Jeanne D. Weiser
1951, Trace Elements Investigations 118
The CO2 combined as calcite in carbonate-bearing apatites as been distinguished from that combined as carbonate-apatite, or present in some form other than calcite, by use of X-ray powder patterns, differential thermal analyses, and differential solubility tests. These methods were applied to several pure apatite minerals, to one fossil bone,...
