Abstract: An automatic micromuffle for the determination of the ash content of small samples of carbonaceous material is comprised of a furnace of the radiant-heating type with a direct reading pyrometer for temperature control. This furnace can be assembled with a minimum of labor using parts available from scientific laboratory apparatus companies.

Report discussing a geological examination of the Chattanooga shale in the general vicinity of the Sequatchie Valley, Tennessee (Block 3) during the period from February 1948 to March 1948. This examination was part of a larger study of the distribution of uranium in the Chattanooga Shale.

From introduction: This report presents, in tabular form, the results of radiometric and geologic reconnaissance made in the Craven and Coal Canyon areas during the period November 27 to December 7, 1951, in accordance with plans outlined in Trace Elements Memorandum Report 152, "The carnotite prospects of the Craven Canyon area, Fall River County, South Dakota." Assay data from the claims examined by L. R. Page and J. A. Redden are not included in this report. This work was done on behalf of the Division of Raw Materials of the U.S. Atomic Energy Commission.

Report discussing an exploratory drilling program in the Charles T. area and vicinity during the period from November 1947 and September 1949. "The purpose of the exploration was to discover new carnotite deposits to support milling operations on the Colorado Plateau, and to appraise the uranium and vanadium resources of the area explored."

A report regarding carnotite resources of the Moon Mesa and Horse Mesa Areas, Mesa Montrose Counties, Colorado.

Abstract: Anomalous radioactivity and uranium minerals have been found on the dumps of the Comet, Gray Eagle, and Silver Hill mines situated along the Comet-Gray Eagle shear zone. The shear zone is from 50 to 200 feet in width and has been traced 5 1/2 miles. The Gray Eagle mine is currently being reopened but no underground work, with the exception of a few shallow shafts and adits, has been done between the Gray Eagle and Comet mines. Because of the high U3 08 content of the samples from the Comet and Gray Eagle dumps, it is recommended that a minimum of four diamond drill holes totaling 3, 000 feet be drilled by AEC between the two mines to intersect the shear zone 300 to 500 feet below the surface. This drilling should be made contingent upon the results of the Gray Eagle exploration.

Report discussing a comparison of three methods of sample splitting for grain counting: the microsplit, the cone splitter, and hand quartering.

A report which investigates three different rock samples that have been contaminated through pulverization in heavy machinery.

Abstract: "All published data on the hafnium content and hafnium/zirconium ratio in minerals and rocks have been compiled." Information regarding hafnium and zirconium content and the ratio Hf/Zr in the earth's crust and in rocks as well as of minerals is included.

A report about a sample of uranium-bearing conglomerate from the Shinarump member of the Chinle formation in northern Arizona was disaggregated in an ultrasonic separator.

A report discussing an examination of the Dismal Swamp property for niobium, tantalum, and uranium.

Report discussing a study in which "a suite of alkalic rocks from the Beemerville, NJ, intrusive body was separated and the percentages of their accessory minerals were determined."

A report about a new quadrivalent vanadium oxide from the Peanut mine named Duttonite which has the formula VO(OH)2. The mineral occurs as crusts and coatings of pale-brown transparent platy crystals.

The following report covers the study of electrical properties of the Morrison formation in the Uravan mineral belt of the Colorado Plateau to determine if there are anomalous variations in these properties in and near zones of uranium-vanadium minerals which might serve as a target for geophysical prospecting.

Report discussing the exploration of the uranium ore-containing ancient channels of the Shinarump member of the Chinle formation of Late Triassic age through the use of a refraction seismograph.

From abstract: Areas of abnormal radioactivity south of Ocala, Marion County, Fla., discovered in 1953 by aerial survey, were investigated by surface examination and by 10 power auger drill holes. Interbedded clay, clayey sand, and uraniferous phosphorite occur in the areas of anomalous radioactivity. Miocene fossils occur at three localities in these beds which are evidently outliers of Miocene sediments on the Ocala limestone of Eocene age. The preserved outliers are southwest of the main belt of Miocene sediments. The principal uraniferous rocks are clayey, sandy, pellet phosphorite that occurs in beds a few feet thick, and very porous, phosphatic sand rock which makes abundant float at many places. Apatite forms the phosphate pellets in the unweathered phosphorite. The very porous, phosphatic sand rock is the highly leached residuum of the pellet phosphorite and is composed mainly of quartz, kaolinite, wavellite, and crandallite ( pseudowavellite2). It closely resembles the aluminum phosphate rock of the "leached zone" of the Bone Valley formation in the land-pebble phosphate district.
