STRATIGRAPIDC SECTIONS OF THE PHOSPHORIA FORMATION 

IN UTAH, 1947-48 

INTRODUCTION 

As part of a comprehensive investigation of the 

phosphate deposits of the western field begun in 194 7, 

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 western states. 

Although these data will not be fully analyzed for 

several years, segments of the data, accompanied by 

little or no interpretation, will be published as preliminary reports. This report, which contains abstracts of many of the sections measured in northeastern Utah (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, 1953a). 

A large number of people have taken part in this 

investigation. The program of which this work is a 

part was organized by V. E. McKelvey. McKelvey, 

J. W. Huddle, D. M. Kinney, J. B. Collins, R. A. 

Gulbrandsen, R. A. Hoppin, J. A. Noel, F. W. 

0 1 Malley, 0. A. Payne, J. F. Rominger, R. P. 

Sheldon, J. E. Smedley, and R. G. Waring participated in the description of strata and collection of 

samples referred to in this report. D. B. Dimick, 

H. A. Larsen, and 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. 

Most of the chemical analyses reported herein 

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. All the samples from one locality 

(Brazer Canyon) were analyzed in the Chemical Laboratory of the Tennessee Valley Authority at Wilson 

Dam, Ala. Some of the Al20 , Fe 0 , and losson-ignition analyses were made in tfie ¥race Elements 

Section laboratory of the Survey in Washington, D. C., 

under the direction of J. C. Rabbitt 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 of Mines in Albany. 

Compilation of the data has been largely by R. P. 

Sheldon and F. D. Frieske under the supervision of 

R. W. Swanson. Organization of the tabular data has 

been largely by Anita C ozzetto. 

Acknowledgments 

Special thanks are due J. SteeleWilliams and A. A. 

Baker who have given much advice and many suggestions 

in the field. The cost of these investigations has been 

borne partly by the Division of Raw Materials of the 

Atomic Energy Commission. This support is gratefully 

acknowledged. 

Many local residents, property owners, and phosphate companies furnished information, gave access to 

property, and extended other courtesies to the field 

parties. The officers of the Humphreys Phosphate 

Company and the American Smelting and Refining 

Company have been especially helpful. 

STRATIGRAPHY OF THE PHOSPHORIA AND 

PARK CITY FORMATIONS IN UTAH 

The stratigraphy of the Permian Phosphoria 

formation in the Crawford Mountains of northeastern 

Utah, near the Idaho-Wyoming corner, is very similar 

to that in the adjacent states and described in companion reports (McKelvey and others, 1953a and b). 

It consists of the phosphatic shale member, about 

210 feet thick, and the Rex chert member, for which 

this is the type locality, about 220 feet thick. The 

upper shale member, present in the adjacent region 

to the north, is not well defined in this area. Here, as well as to the north, the Phosphoria formation overlies the Pennsylvanian Wells formation, the upperpart 

of which consists chiefly of cherty gray limestone with 

some thin phosphatic layers. The Phosphoria is overlain by the Triassic Dinwoody formation, consisting 

of limestone, calcareous siltstone, and sandstone. A 

generalized section of the Phosphoria formation at 

Brazer Canyon is shown in figure l. 

Farther south, along both the north and south flanks 

of the Uinta Range and in the general area of the Wasatch 

Range, the Park City formation is the partial stratigraphic equivalent of the Phosphoria formation, At Park 

City, its type locality, it is about 590 feet thick and consists of a lower limestone member, which may be stratigraphically equivalent to the upper part of the Wells 

formation in southeastern Idaho; a middle shale member 

(phosphatic but containing no high-grade phosphate beds) 

probably equivalent in major part to the phosphatic shale 

of Idaho; and an upper limestone member, equivalent to 

the Rex chert member to the north. Eastward the lower 

limestone member thins out and the phosphatic shale and 

upper limestone members thin, are more clastic, and 

finally tongue out into nonmarine redbeds in eastern Utah 

and western Colorado. Westward the formation thickens 

markedly, attaining a thickness of several thousand feet, 

and contains a greater proportion of chemical precipitates. 

More detailed correlations of the strata within Utah as 

well as between Utah and adjacent states will be discussed 

in subsequent publication.

UPPER BRAZER CANYON, UTAH. LOT NO. 1228. 

Phosphatic shale member of Phosphoria formation sampled in bulldozer trench on north side of Upper Brazer Canyon, sec. 30, T. 11 N. R. 8 E., 

Rich County, Utah, on east limb of syncline. Beds strike N. 36° E. and dip 39° W. Section measured by V. E. McKelvey, J. E. Smedley, R. A. Hoppin, 

and F. W. 0' Malley and sampled by R. G. Waring, J. A. Noel, and R. P. Sheldon in June and July 1948. Samples analyzed for P 0 and acid insoluble 

by U. S. Bureau of Mines Laboratory, Albany, Oregon, and for other constituents by Trace Elements Section Laboratory, U. S. beBlogical Survey,

The contact between the Wells and Phosphoria formations is indistinct. VEM-1057 is believed to be below VEM-1031, though brecciation 

makes this uncertain. Since VEM-1057 is the lowest dark-colored bed exposed in the trench, it is taken as the base of the Phosphoria. 

However, about 75 feet east and probably 50 feet or more lower stratigraphically is an outcrop of black limestone typical in appearance 

of Phosphoria. ----------
