A series of reports presenting detailed stratigraphic sections and analyses of samples of the Phosphoria formation in the western phosphate field is being prepared for publication as U. S. Geological Survey Circulars. To speed the availability of these data to industry and others having immediate need for such basic information, many of the tables already typed and photographed were reproduced without text and placed on open file in advance of publication. This includes six reports of data gathered during the 1947 and 1948 field seasons.

Stratigraphic sections of the phosphoria formation in Utah, 1949-1951

As part of a comprehensive investigation of the phosphate deposits of the western field begun in 1947, the U.S. Geological Survey has measured and sampled the full thickness of the Permian Phosphoria formation and its partial correlative, the Park City formation, at many localities in Utah and other states. Although these data will not be fully analyzed for several years, segments of the data, accompanied by little or no interpretation, are published as preliminary reports as they are assembled. This report, which contains abstracts of the sections measured in northeastern Utah in 1949, 1950, and 1951, is one of this series and the second report of data gathered in Utah. The field and laboratory procedures adopted in these investigations are described rather fully in a previous report (McKelvey and others, 1953a). Many people have taken part in this investigation. The program which this work is a part was organized by V. E. McKelvey and the field program was supervised by R. W. Swanson. R. P. Sheldon assisted in the location and selection of sample localities and F. J. Anderson, McKelvey, Sheldon, and H. W. Peirce participated in the description of strata and the collection of samples referred to in this report. T. K. Rigby assisted in the preparation of trenches and the crushing and splitting of samples in the field. The laboratory preparation of samples for chemical analysis was done in Denver, Colo., under the direction of W. P. Huleatt.

Stratigraphic sections of the Phosphoria formation in Wyoming, 1949-50

As part of a comprehensive investigation of the phosphate deposits of the western field begun in 1947, the U.S. Geological Survey has measured and sampled the Phosphoria formation of Permian age at many localities in Wyoming and adjacent states. These data will not be fully synthesized for many years, but segments of the data, accompanied by little or no interpretation, are published as preliminary reports as they are assembled. This report, which contains abstracts of the sections measured in western Wyoming (figs 1 and 2) in 1949 and 1950, is the second Wyoming report of this series. The field and laboratory procedures adopted in these investigations are described rather fully in a previous report (McKelvey and others, 1953a). Many people have taken part in this investigation, which was organized and supervised by V. E. McKelvey and most of the field program was supervised by R. W. Swanson. F. J. Anderson, D. F. Davidson, A. M. Gutstadt, J. W. Hill, H. W. Peirce, W. R. Record and M. E. Thompson participated in the description of strata and the collection of samples referred to in this report. T. K. Rigby assisted in the preparation of exposures and the crushing and splitting of samples in the field. The laboratory preparation of samples for chemical analysis was done in Denver, Colo., under the direction of W. P. Huleatt.

Stratigraphic sections of the Phosphoria Formation in Idaho, 1949: part II

The U.S. Geological Survey has recently 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 are assembled. This is the fifth report of data containing abstracts of sections measured in southeastern Idaho; it includes about half of the data gathered in Idaho in 1949. The field and laboratory procedures adopted in these investigations are described rather fully in a previous report (McKelvey and others, 1953a). Many people have taken part in this investigation, which was organized and supervised by V. E. McKelvey. F. J. Anderson, A. L. Bush, R. S. Jones, K. B. Krauskopf, K. Lutz, M. E. Thompson, R. G. Waring, and M. A. Warner participated in the description of strata and the collection of samples referred to in this report. T. K. Rigby assisted in the preparation of trenches and the collection, crushing, and splitting of samples in the field. The laboratory preparation of samples for chemical analysis was done in Denver, Colo., under the direction of W. P. Huleatt.

Stratigraphic sections of the phosphoria formation in Idaho, 1950-51

The U.S. Geological Survey has recently 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 are assembled. This report, which contains abstracts of the sections measured in southeastern Idaho (fig. 1), is one of this series and is the sixth report of data gathered in Idaho; it includes the data gathered in Idaho during 1950 and 1951. The field and laboratory procedures adopted in these investigations are described in a previous report (McKelvey and others, 1953a). Many people have taken part in this investigation. E. R. Cressman, F. D. Frieske, R. A. Gulbrandsen, H. W. Peirce, J. A. Peterson, B. K. Replogle, and M. A. Warner participated in the description of the strata and the collection of samples referred to in this report. Crushing and splitting of samples in the field were done by T. K. Rigby. The laboratory preparation of samples for chemical analysis was done in Denver, Colo., under the direction of W. P. Huleatt.

Stratigraphic sections of the Phosphoria formation in Wyoming, 1952

The U.S. Geological Survey has measured and sampled the Phosphoria formation of Permian age at many localities in Wyoming and adjacent states. These data will not be fully synthesized for many years, but segments of the data, accompanied by little or no interpretation, are published as preliminary reports as they are assembled. This report, which contains abstracts of the sections measured in western Wyoming (fig. 1), during 1952, is the fourth Wyoming report of this series. The field and laboratory procedures adopted in these investigations are described rather fully in a previous report (McKelvey and others, 1953a). Many people have taken part in this investigation. T. M. Cheney participated in the description of strata and the collection of samples referred to in this report and T. K. Rigby assisted in the collection of samples. The laboratory preparation of samples for chemical analysis was done in Denver, Colo., under the direction of W. P. Huleatt.

Stratigraphic sections of the Phosphoria formation measured and sampled in 1951

The first four of a series of reports giving detailed stratigraphic sections and analyses of samples of the Phosphoria formation in the western phosphate field as described and sampled by the U. S. Geological Survey will soon be published as Circulars 208 through 211. Because of the needs of industry for many of these data during the 1951 field season, and owing to unavoidable delays attendant on publication, the tabular data prepared for these four and for two additional circulars, as yet unnumbered, were released on open file without texts or maps last year. These six reports constitute a summary of all the sampling done by the U. S. Geological Survey in the western phosphate field during 1947 and 1948. The analytical returns on the samples collected during 1949, 1950, and 1951 were incomplete at that time. However, in keeping with the objectives outlined above, abstracts of the stratigraphic units and P205 and acid insoluble analyses of the phosphatic parts of the sections measured and sampled during 1949 and 1950 were released on open file as two reports so that early use might be made of the most important economic data collected during this field work. This is a similar report covering the 1951 field season data. The data in these three open file reports are being prepared for publication in circulars like the six reports mentioned above. These reports, as well as others referred to, are placed on open file at the offices of the U. S. Geological Survey in Washington, D. C.; Spokane, Washington; Salt Lake City, Utah; and Montpelier, Idaho (open from May to October), and at the offices of the Idaho Bureau of Mines and Geology, Moscow, Idaho; the Montana Bureau of Mines and Geology, Butte, Montana; the Wyoming Geological Survey, Laramie, Wyoming; and the University of Utah, Salt Lake City, Utah.
