STRATIGRAPHIC SECTIONS OF THE PHOSPHORIA FORMATION IN UTAH by V. E. McKelvey, L. E. Smith, D. M. Kinney, J. W. Huddle, G. F. Hosford, R. S. Sears, D. P. Sprouse, and M. D. Stewart INTRODUCTION The first of a series of reports giving detailed stratigraphic sections of the Phosphoria formation in the Western phosphate field as measured and described by the Geological Survey will be released as Circulars within the next few months. Because of the needs of industry for many of these data during the 1951 field season, and in view of the unavoidable delays attendant on publication: the tabular data to be included in these Circulars are hereby placed on open file in simple reproduction form (prepared by Ozalid from photographic negatives) and without explanatory text so that immediate use may be made of the data. The t ables include data on sections in four states: Montana, Idaho, Wyoming, and Utah; and the tables for each of these states are bound together as individual reports. The tables include name and location of section measured, brief descritnion of geologic setting, acknowledgments for field and analytical work, abstract data on the sections (bed number, rock name, sample number, and thickness), and analytical data or the samples. The analytical data include reports on P,05,and acid insoluble for all samples and additional analyses, such as A1,03, Fe2O3, loss on ignition, F, and V205* for selected samples. Spectrographic analyses for a large number of elements are included for samples from selected localities, and special analyses have been made of a few samples. These reports are placed on open file at the offices of the Geological Survey in Washington, D. C., Spokane, Washington, Salt Lake City, Utah, and Montpelier, Idaho, and at the offices of the Idaho Bureau of Mines and Geology, Moscow, Idaho, the Montana Bureau of Mines and Geology, Butte, Montana, and the Wyoming Geological Survey, Laramie, Wyoming, and the University of Utah, Salt Lake City, Utah.
BRAZER CANYON, UTAH. LOT NO. 1203. Phosphoria formation sampled in Brazer Canyon, sec. 18, T. 11 N., R. 8 E., Rich County, Utah, on west limb of Crawford Mountains syncline. Section pieced together from two overlapping hand trenches and natural outcrops. Beds P-1 to P-60 sampled in lower trench, beds P-61 to P-139 sampled in upper trench, and beds R-1 to R-3S sampled in upper trench and natural outcrops. Upper trench overlaps lower trench 40 feet; it and natural outcrops lie 50 feet above lower trench. Beds strike north and dip 60° E. Section measured by V. E. McKelvey, L. E. Smith, and R. A. Hoppin and sampled by R. P. Sheldon, 0. A. Payne, R. A. Gulbrandsen, and R. S. Sears in July 1947. Samples analyzed by Tennessee Valley Authority. Bed no. Rock description Sample no.

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.
