Radiometric Examination of Rock Specimens from Mount McKinley, Alaska
Abstract: A suite of 50 rock specimens, collected by the 1947 Washburn Mount McKinley Expedition, was scanned radiometrically. The maximum radioactivity observed in any one of the specimens was about twice background. Radiometric analyses of the most radioactive samples show that a sample of vein quartz coated with manganese oxide contains 0.009 percent equivalent uranium and that the maximum equivalent uranium content of granitic rock types is .004 percent. The radioactivity of the manganese-stained quartz is probably due to traces of uranium in the manganese mineral, whereas that of the granitic rocks is due to radioactive accessory minerals.

A Semiquantitative Spectrographic Method for the Analysis of Minerals, Rocks, and Ores ([Part] 2)
Abstract: The scope of the semiquantitative spectrographic method for the analysis of minerals, rocks, and ores previously described as determining 55 elements, has now been increased to 68 elements which can be estimated in one exposure of a l0-mg sample. Fluorine, the 69th element, requires a separate exposure for some materials. The method has been used to complete about 185,000 determinations in the past two years. Listed in this report are 336 chemical check analyses that indicate approximately 8 percent disagreements in the magnitude of one 10 percent bracket. No chemical and spectrographic results differ by a factor of more than 10.

Preliminary Report of the Results of Reconnaissance for Uraniferous Materials in the Powder River Basin, Wyoming
From introduction: During three months of the summer of 1952, a geologic and radiometric reconnaissance examination for uraniferous materials in the peripheral parts of the Powder River structural basin in northeastern Wyoming (fig. 1) was made by the Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. The purpose was to find, describe, locate, and sample deposits of uraniferous or radioactive materials other than those in the central part of the Powder River Basin in the general vicinity of the Pumpkin Buttes.

Preliminary Index to Geological Survey Trace Elements Reports on Alaska for the Period January 1945-December 1952
From introduction: Since 1945 the Alaskan Trace Elements Unit of the U. S. Geological. Survey has been engaged in reconnaissance for radioactive deposits in Alaska, first on behalf of the Manhattan Engineer District, later on behalf of the Atomic Energy Commission. During the period January 1945 through December 1952, 42 reports in the Survey's Trace Elements Investigations series and 18 reports in the Trace Elements Memorandum series, a totaJ of 60 reports, have been completed or are in preparation Of these 60 reports 44 have been completed and transmitted to the Commission as of December 31, 1952.

Uranium and Phosphate in the Western Part of the Bonny Lake Mine, Polk County, Florida
From abstract: During the month of May 1950, the Davison Chemical Corporation, under contract with the Atomic Energy Commission, drilled 24 phosphate prospecting holes in the western part of the Bonny Lake mine, in the SW NW4 and the NW*SW4 sec. 32, T. 29 S., R. 24 E., Polk County, Fla. The purpose of this drilling was to obtain a comparison between tonnage and grade of uranium in the phosphate as indicated by prospecting, and the tonnage and grade of uranium in the phosphate products recovered in the mill. The results presented in this paper are based upon a study of drill cores, drill logs, gamma-ray logs, and the chemical analyses of drill-core samples.

Preliminary Report on Diamond-Drill Exploration of Parts of Blue and Moon Mesas, Mesa County, Colorado
From abstract and summary: The Blue and Moon Mesa areas are about 13 miles southeast of Gateway, Mesa County, Colo. Total production of carnotite ore from the Blue and Moon Mesa areas has been about 1,000 short tons that averaged about 0.25 percent U30Oand 1.75 percent V205. Most of this production was obtained from 1940 to 1943 and in 1949. The U. S. Geological Survey explored the northern parts of these areas by diamond drilling between August 9 and December 14, 1950. The Survey drilled 113 holes, totalling 16,039 feet. This drilling was mostly wide-spaced and was done to obtain geologic information.

Wagon-Drill Sampling by U.S. Geological Survey
Abstract: For a number of years the Geological Survey has employed core drilling as a means of obtaining samples of underground formations for use in exploring and evaluating mineral deposits. During 1951, however, experiment with less expensive methods showed that, for analytical purposes, wagon-drill cuttings could be used as effectively as cores, provided a practical method were devised for recovering them in suitable form. The recent development of such a method has made it possible, in places where the depth of drilling does not exceed 125 feet, to supplant thousands of feet of core drilling by wagon drilling which is much faster and which can be done at approximately one-third the cost of the former method. This report describes the sampler and discusses performance, maintenance, and operating costs.

Water Resources of the North Coast Limestone Area, Puerto Rico
From introduction: The North Coast Limestone area is one of the two most important ground-water provinces of Puerto Rico--the other being the South Coast Alluvial aquifer. The investigation of the water resources of the South Coast has progressed to the point that at this time (mid-1971) an electric-analog model of the area is being prepared. The hydrology of the North Coast Limestones, however, was never investigated as a whole before this investigation, and, therefore, this study was designed to assess the most important hydrolic features of the area.
