From introduction: An autunite deposit in the SW 1/4 sec. 25, T. 10 N., R. 13 W. San Bernardino meridian, was visited by F. M. Chace on May 6 and 15, 1950. The deposit is about 100 yards west of a north-south country road and is at an altitude of approximately 2,775 feet. The autunite-bearing tuffaceous sandstone strikes N. 35-40 W. and dips 20 -25 SW. It has been traced about 40 feet along the strike at the base of the outcrop and for about 20 feet up the dip. Insufficient work was done to give an accurate idea of the size of the deposit or to determine if other autunite-bearing beds are present.

Report discussing a geological study for which the objective was to determine the age of Colorado Plateau carnotite. "In addition to quantitative analyses of uranium and lead, the radium-uranium equilibrium of each sample was studied."

Report discussing a study in which "thorium nitrate is quantitatively extracted by mesityl oxide from solutions saturated with aluminum nitrate even in the presence of relatively large amounts of phosphate."

Report discussing a study of 1,000 Gamma-ray logs of oil wells in the central part of the United States which confirmed the use of these logs for the detection of radioactive deposits.

Report discussing a geological experiment in which drill holes in carnotite deposits were logged with the objective of developing a technique for the stratigraphic correlation of ore-bearing beds.

Report discussing geologic structures which localize carnotite deposits of the Colorado Plateau.

The following report is the result of a reconnaissance of the black shales of the Eastern United States in the summer of 1944. The purpose of this reconnaissance was to determine the radioactivity of the shales, specifically for uranium and thorium.

The following interim report provides information on the radioactivity discovered in the Chattanooga shale that consist of a basal sandstone, a lower black shale, a middle gray shale, and an upper black shale.

The following report is based on the findings of a Geological Survey party who spent one week during July 1944 in western North Carolina testing some of the Pegmatites and one Kyanite mine of that region for radioactive minerals.

Report discussing a fluorimeter intended for use in the fluorimetric method of analysis for uranium. This particular fluorimeter measures fluorescence by transmission rather than by the usual "reflection" methods.

Report discussing a study in which "hydrated uranyl vanadates of potassium, sodium, ammonium, calcium, strontium, and barium were synthesized as part of a mineralogic study of carnotite and tyuyamunite."
