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 Montana, 1949-50: part I
The U.S. Geological Survey has recently measured and sampled the Phosphoria formation at many localities in Montana and other western 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 southwestern Montana (fig. 1) is one of this series and is the third Montana report; it includes about half of the data gathered in Montana during 1949 and 1950. The field and laboratory procedures adopted in these investigations are described rather fully in a previous report (McKelvey and others, 1953). 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, T. M. Cheney, J. L. Elliott, F. D. Frieske, R. F. Gosman, R. S. Jones, B. K. Replogle, and R. G. Waring participated in the description of strata and the collection of samples referred to in this report. Crushing and splitting of the samples in the field was 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.

The program of which this work is a part was organized by V. E. McKelvey. J. L. Elliott, W. J. Garmoe, R. F. Gosman, C. W. Tandy, and W. H. Wilson participated in the description of strata and the collection of samples referred to in this report. Crushing and splitting of the samples in the field was done by T. K. Rigby.

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.

This report, which contains abstracts of the sections measured in southeastern Idaho (fig. 1), is one of this series and is the fourth report of data gathered in 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, D. F. Davidson, R. S. Jones, R. A. Smart, R. G. Waring, and J. D. Weiser 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.
