Stratigraphic sections of the Phosphoria formation measured and sampled in 1952

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 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.

Stratigraphic sections of the Phosphoria Formation in Montana, 1949-50: part II

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 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 many of the sections in southwestern Montana (fig. 1), is one of this series and is the fourth Montana report; it includes the second 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 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. 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.

Geology of the Dry Valley quadrangle, Idaho; a preliminary report

The Dry Valley quadrangle is one of seven 71-minute quadrangles in southeastern Idaho being mapped by the U. S. Geological Survey as part of an investigation of the western phosphate field. This work was done on behalf of the Division of Raw Materials of the Atomic Energy Commission. Most of the quadrangle was mapped on a new 1:12,000 topographic base during the summer and fall of 1950 by E. R. Cressman and R. A. Gulbrandsen with the assistance of K. B. Krauskopf, K. Lutz, and J. W. Hill. The field work was completed in the fall of 1951 by Cressman and assisted by R. G. Waring and M. A. Warner. This quadrangle is the NEI of the Slug Creek 15-minute quadrangle, which was mapped by Mansfield (1927) at a scale of 1:62,500.

Stratigraphic sections of the Phosphoria in Montana, 1947-48

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 and analyzed for several years, but segments of the data, accompanied by little or no interpretation, will be published as preliminary reports as they are assembled. This report, which contains abstracts of many of the sections measured in southwestern Montana (pl. 1), is one of this series. The field and laboratory procedures adopted in these investigations are described rather fully in a companion report (McKelvey and others, 1952). Many people have taken part in this investigation. The program of which this work is a part was organized by V. E. McKelvey. J. G. Evans, J. E. Joyce, J. A. Kelleher, R. L. Konizeski, J. A. Mann, R. L. Parker, J. E Smedley, L. A. Thomas, and W. H. Wilson participated in the description of strata and collection of samples referred to in this report. The laboratory preparation of samples for chemical analysis was done in Denver, Colo., under the direction of W. P. Huleatt. All the P 2 O 5 , F, V 2 O 5 , and acid-insoluble analyses were made for the Survey by the U. S. Bureau of Mines at the Northwest Electrodevelopment Laboratory, Albany, Oreg., under the direction of S. M. Shelton and M. L. Wright. The Al 2 O 3 , Fe 2 O 3 , and loss-on-ignition analyses were about equally distributed between the Bureau of Mines and the Trace Elements Section laboratory of the Survey in Washington, D. C., under the direction of J. C. Rabbit by chemists I. Barlow, A. Caemmerer, J. Greene, N. Guttag, and E. H. Humphrey. The spectrographic analyses were made by D. M. Mortimer, of the Bureau Mines in Albany, and the oil-shale analyses were made by the Bureau of Mines Petroleum and Oil-Shale Experiment Station at Laramie, Wyo. Compilation of the data has been largely by R. P. Sheldon and F. D. Frieske. Organization of the tabular data has been largely by Anita Cozzetto.
