A terminology is suggested to aid the field geologist in describing the structures of stratified and cross-stratified rock units. Qualitative terms describing the character of rock layering are stratification, stratum, cross-stratification, cross-stratum, set, coset, and composite set. Quantitative terms applying to the thickness of stratification are very thick-bedded, thick-bedded, thin-bedded, very thin-bedded, laminated, and thinly laminated. Quantitative terms...

The Dolores bench is about 2 miles northwest of Uravan, Montrose County, Colo. From 1913 to November 1952 about 95,000 short tons of ore averaging 0.40 percent U3O8 and 2.0 percent V2O5 was mined from the Dolores bench. The production represents three periods of activity--1913-18, 1938-43, and 1948-52. The ore deposits...

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...

The U.S. Geological Survey has recently measured and sampled the Phosphoria formation 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...

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...

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...

The Shinarump No. 1 uranium mine is located about 12 miles northwest of Moab, Utah, in the Seven Mile Canyon area, Grand County, Utah. A study was made of the geology of the Shinarump No. 1 mine in order to determine the habits, ore controls, and possible origin of the...

Channel samples of the commercially important coal beds and associated rocks in the Pottsville, Allegheny, and Monogahela series of the Pennsylvanian system were collected in eastern Ohio. Equivalent uranium content of 0.001 percent or more was determined in the laboratory for five samples. The uranium content of the coal is...

Data collected at the Topaz Relocation Center provide an excellent record of the development and subsequent disappearance of a cone of depression caused by pumping. This Center occupied temporarily an area of natural ground‐water discharge on the floor of the Sevier Desert in west‐central Utah. Water for a population of 6500 was pumped from artesian wells which tapped aquifers...

In 1952 the National Park Service became interested in setting aside a large wilderness area in northeastern Alaska. The area is approximately 7,000 square miles in size, with boundaries as follows: beginning at Camden Bay south along the Katakturuk River to lat. 68° N.; then east to long. 144° 33'...

Uranium minerals were found on October 15, 1953, about seven miles west of Baggs in the Browns Park formation of the Poison Basin area, Carbon County, Wyo. The occurrences extend over an area of at least several square miles in secs. 4 and 5, T. 12 N., R. 92 W.,...

Uranium-bearing coal in the Wasatch formation occurs in a zone extending 30 miles north of U.S. Highway 30 and the Union Pacific Railroad at Wamsutter, Sweetwater County, Wyoming. The Wasatch formation intertongues with the Green River formation and the beds are nearly flat lying. Preliminary estimation of total reserves in...

The Red Canyon quadrangle is one of eighteen 7 1/2-minute quadrangles covering the principal carnotite-producing area of southwestern Colorado. The geology of these quadrangles was mapped by the U.S. Geological Survey for the Atomic Energy Commission as part of a comprehensive study of carnotite deposits. The rocks exposed in...

The Peace River area, comprising T. 30 and 31 S., R. 24 and 25 E., contains a thicker and more persistent aluminum phosphate zone, and one that is higher in P2O5 and uranium content than is known elsewhere in the land-pebble phosphate district. This report has been prepared to bring...

The accompanying map shows the results of an airborne radioactivity survey in an area of 154 square miles in Uinta county, Wyoming. The survey was made by the U.S. Geological Survey, October 23, 1952, as part of a cooperative program with the U.S. Atomic Energy Commission. The survey was made...

During the last quarter of 1952 and most of 1953 the U.S. Geological Survey carried on a program of reconnaissance for radioactive material in the southeastern states on behalf to the Atomic Energy Commission. In the course of the study 111 localities were examined and 43 samples were taken for...

A sample of subbituminous uraniferous coal from the Red Desert, Sweetwater County, Wyo., was studied mineralogically. The coal contains gypsum (6 percent), kaolinite (1 percent), quartz (0.3 percent), calcite (trace), and limonite (trace). This suite of minerals and the absence of pyrite show that the coal has been subjected to...
