From outline: This paper, after discussing general principles connected with the study and description of the Tertiary or Cenozoic rocks and fossils contained in them, takes up the Neocene deposits of the United States in particular. A chapter is devoted to a summary of what is known in regard to the Neocene of the eastern coast of the United States, each State in geographical order being separately considered, beginning at the north.

From preface: "This report is a compilation of the significant metalliferous lode deposits and placer districts of Alaska, and is a comprehensive data base for a companion article on the metallogenesis and major mineral deposits of Alaska that will be published in the volume of Alaskan geology for the Decade of North American Geology (DNAG) by the Geological Society of America."

The survey covered in this documentation was conducted in Southcentral Alaska that included the Cook Inlet and Kenai Peninsula regions of Alaska comprising six quadrangles. The survey was performed between 1976 and 1978 under the United States Department of Energy's National Uranium Resource Evaluation (NURE) Program. This program provides information on reconnaissance radioelement distribution to assist in assessing the uraniferous material potential in the United States.

Final report documenting a high-sensitivity airborne radiometric and magnetic survey of the Skagway, Atlin, Mt. Fairweather, Juneau, Taku River, Sitka, Port Alexander, Sumdum, Petersburg, Bradfield Canal, Craig, Dixon Entrance, Ketchikan, and Prince Rupert quadrangles including the survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

From Introduction: "The analyses given in this bulletin are of samples of delivered coal. This bulletin gives the results of analyses of samples delivered coal collected from July 1, 1915 to January 1, 1922."

A collection of papers which report on the geologic investigations in Alaska. It represents the broad range of U.S. Geologic Survey research activities carried out in Alaska.

Report displays a bibliography of numerous literature affirms air pollution has been a problem through the centuries.

Report published by the U.S. Bureau of Mines containing the results of a survey of the natural gas resources available in the United States. From the summary:"The Results of a Bureau of Mines survey of helium resources are given in this report and comprise gas analyses and accompanying data on more than 2,100 samples that have been collected in 30 States. The survey to determine the Nation's helium resources has been carried on in all natural-gas-producing areas of the United States since the inception of the Government's helium program in 1917. The primary purpose of the report is to present the results of this work in a tabulated form. A secondary purpose is to make public the historical background of the helium survey and to describe the methods of collecting gas samples and analyzing them. Detailed descriptions are given of the analytical equipment and procedures used in making the analyses" (p. 1).

From Introduction: "Information concerning the fusibility of coal ash has become of considerable value to the consumer of coals, mainly in connection with the troublesome formation of clinker from the melting of the ash constituents of the burning coal. It is hoped that this information when used together with the large number of coal analyses published by the bureau will assist the consumer of coal in comparing different coals, and in selecting the coal best adapted for his purpose."
