First part of an annual report describing studies conducted by researchers at Columbia University to surveyuranium mineralization in the Marysvale, Utah region: "Part I deals with field studies and mineralogical data derived from the laboratory examination of suites collected during the previous summer" (p. 5).

Introduction: During the year 1952-1953, research on the Boulder batholith program was largely devoted to basic mineralogy studies of the "siliceous reef" and, to the extent possible at that time, the "base metal" deposits.

Introduction: This is the fifth of a series of reports covering technical progress on the research and development program being performed in connection with the design of the Pathfinder Atomic Power Plant.

From introduction: A trip into the Henry Mountains area occupied the days from March 6 to 9, 1951, inclusive, excepting March 7, which was used to examine Reo Hunt's deposit in Poison Spring Wash. Observations were made on stratigraphy, regional geology, and the locations of the known deposits of uranium and vanadium.

Introduction: This volume is the second in a series of reports dealing with the recovery of uranium, alumina, and phosphatic values from the leached zone portion of he Florida phosphate producing area.

Abstract: In the event of a massive nuclear attack, the combined fallout from quantities of surface-burst nuclear weapons must be considered as a serious hazard over an extended area. This report presents one method for rapidly estimating the fallout from such an attack.

From abstract: Seismic waves resulting from a 5 kiloton nuclear detonation 1200 feet deep in a salt bed near Carlsbad, New Mexico were measured by strong-motion seismographs operated by the Coast and Geodetic Survey on the surface in the distance range from 0.5 to 8.8 miles and underground in a potash mine 8.7 to 11.2 miles distant.

Report on an evaluation of the Sand Springs Range as a possible location for an underground nuclear study (Shoal Event). Various tests to determine the site's suitability included aerial photography and mapping of the area through various means; drilling and bulldozing to conduct mineralogical and other physical evaluations; gravity, aeromagnetic, and refraction surveys; and studies related to the hydrology of the location and surrounding areas.

Abstract: The Free Enterprise property is located in the Boulder mining district, Jefferson County, Montana. Secondary uranium minerals occur here in small irregular concentrations in and adjacent to a narrow silicified fracture zone in quartz monzonite.

from Introduction: The National Bureau of Standards has designed, constructed, and evaluated a standard for the support of very-high-frequency omnidirectional range (VOR) air navigation aids. The standard consists of two instruments: (1) a digital waveform signal generator for the composite VOR audio waveform, and (2) a standard phasemeter based on time series analysis of this waveform. Experimental results, a statistical analysis of them, and the principal software listings are included.

Abstract: A low-level airborne radioactivity survey of parts of Beaverhead and Madison Counties in southwestern Montana was undertaken from June 6 to October 14, 1955. Flying centered around the Ruby Range-Sweetwater Basin area and concentrated on the Precambrian metamorphic complex and Tertiary lake-bed sediments. No commercial uranium deposits were discovered, and no extensions were found of the few known small occurrences. Five areas of high background detected through the survey were investigated on the ground.

General purpose of survey: During the period 1943 and 1944, the primary purpose was to locate, describe, sample, and generally evaluate the SOM-vanadium mineralization in the western Carrizo Uplift and Chuska Mountains Areas. To this end, the areal geology of the areas, with emphasis on the Salt Wash member of the Morrison formation, was mapped. The triangulation and the laying out of leased plots were supplemental parts of this work. The field work in 1945 was for the purpose of collecting additional and supplemental geological data in order to complete the record and to calculate the ore reserves of the areas.

Abstract: Uranium ore deposits on two exposed rims and past production records of tonnage and grade indicate an exploration program is justified in the Oak Springs area. A minimum of 24,000 feet of core drilling is recommended with a maximum of 75,000 feet to be based on favorability as determined by subsurface studies.

This report presents maps on the geology of the Western Carrizo Uplift and the Chuska Mountains of Arizona in the Northern Navajo Indian reservation.

Introduction: Vanadium ore is being mined at many places in western Colorado, southeastern Utah, northeastern Arizona, and northwestern New Mexico (fig. 1). Eight mills in this region produced about 4,300,000 pounds of V2 05 in 1942, representing about 90 percent of the vanadium obtained from domestic sources. Although ore production has mostly exceeded mill capacity since 1937, production during the last half of 1942 averaged only about 19,000 tons or ore a month, whereas the capacity of these mills total about 22,000 tons a month. At the expected rate of ore production, ore stockpiles will be exhausted sometime in 1944, and these mills will then have excess capacity. With more intensive prospecting than now practiced, however, it is believed that sufficient reserves can be indicated to sustain capacity operation of these mills for several years. This memorandum is prepared to specify those areas that are considered most favorable from a geologic standpoint for developing large reserves of vanadium ore by prospecting. It is based on intensive studies by the Geological Survey since 1939 in most of the areas that produce vanadium ore.

Purpose and scope: The purpose of this report is to present an analysis and evaluation of the airborne radioactivity survey of the Blanding, Utah district conducted by The Texas Company on behalf of the Atomic energy Commission. Within the scope of the report, only the results of the airborne survey and the data used in its evaluation are presented. No attempt is made to discuss the details of the survey or of the drilling program conducted in the area. A separate report by P. 1. Melanoon, on the drilling program is in preparation.

Abstract: This report consists of four parts, the first three being descriptions of investigations compiled in the period October 1st, 1953 to April 1st, 1954; the fourth part is a summary of progress of the research based on our entire investigations completed prior to April 1st, 1954. The first part comprises a set of preliminary experiments investigating the mineral composition of the sandstones in thin sections, in an attempt to differentiate barren from ore-bearing sandstones. It appears that there are more rock-fragments and particularly more volcanic rock fragments in the ore zone (zone 4, Well C, Bull Canyon). In addition, silica cement appears to be associated with ore and carbonate cement with barren sediments. The second part details the investigation of the mudstones of the Bull Canyon Wells . A mixed layer lattice "illite" and a kaolin mineral are the most prominent in "normal" mudstones. Dye tests suggest there are differences between the clay minerals in the sandstone matrix of the ore zone and barren zone. In addition, the mudstone zones appear to differ in the response to the dye tests. The third part of the report details the bulk density determinations for cores from well B. The results confirm …

During the summer of 1975, the Alaska Division of Geological and Geophysical Surveys (DGGS) conducted a 6-week reconnaissance in widespread areas of Alaska as part of the National Uranium Resource Evaluation (NURE) program sponsored by the Department of Energy (DOE). Water, stream sediment, and bedrock samples were taken from the eastern Seward Peninsula, from north of Koyukuk River, from the Charley River area, and from across south-central Alaska, to aid in determining the uranium potential of the state.

From introduction: This report describes work done in the Rawlins, Wyoming, National Topographic Map Series (NTMS) quadrangle (US Geological Survey, 1968) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From abstract: During the summer of 1977, 1268 water and 1206 sediment samples were collected from 1292 lakes and streams throughout the 33 600-km2 area within the boundaries of the McGrath and Talkeetna National Topographic Map Series quadrangles in south-central Alaska. Each of the water samples was analyzed for uranium and 12 other elements, and each of the sediment samples was analyzed for uranium, thorium, and 41 other elements. All of the field and analytical data are listed in appendixes to this report, but only the uranium and thorium data are discussed herein.

Abstract: The results of analyses of the airborne gamma radiation and total magnetic field survey flown for the region identified as the Tonopah National Topographic Map NJll-5 is presented in Volume I and II of this report. The airborne data gathered is reduced by ground computer facilities to yield profile plots of the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units. The distribution of data within each geologic unit, for all surveyed map lines and tie lines, has been calculated and is included. Two sets of profiled data for each line are included with one set displaying the above-cited data. The second set includes only flight line magnetic field, temperature, pressure, altitude data plus magnetic field data as measured at a base station. A general description of the area, including descriptions of the various geologic units and the corresponding airborne data, is included also.
