From Abstract: "This report describes the occurrence of the mica and its physical properties among which is an unusually wide range of colors. A table is presented showing the results of power-factor measurements made by the National Bureau of Standards on 196 samples of sheet mica from 109 mica mines and 15 feldspar mines.It is concluded that more systematic planning of mica mining, for the district as a whole. would result in an average yearly production of at least 90,000 pounds of relatively clear sheet and possibly much more."

From abstract: The area comprising the first flood plain downstream from the headwaters of Knob Creek was one of three monazite placer deposits near Shelby, N. C., recommended by the Geological Survey for investigation by the Bureau of Mines as a joint effort by the above two agencies. Past production of monazite from the headwaters of this stream and its drainage of an area of known source rocks were factors influencing this selection. Drilling of the deposit was started on November 26, 1951, and completed December 29, 1951. Twenty-two churn-drill holes were completed to bed-rock on 112 acres of this flood plain for a total depth of 433 feet of vertical drilling.

Introduction: Part 2 of the Systematic Report continues and concludes the study of the Mollusca from the Miocene and lower Pliocene of Virginia and North Carolina. One hundred and nineteen species, only a fraction of the known fauna, are reviewed and 66 additional species are described and figured. (See faunal chart, pp. 180-183.) The report upon the gastropods suffers from the same shortcomings obvious in the work on the pelecypods. Most of the material is from old collections made before the importance of the exact placing of the fossil locality both areally and vertically was recognized. Many of the citations of outcrops are vague and the sections generalized. Detailed field studies, particularly on the zoning of the Yorktown formation in southern Virginia and northern North Carolina, were begun later by Wendell P. Mansfield, but he died in the summer of 1939 before the completion of the work.

Introduction: The investigation of monazite deposits in the southeastern states by the Bureau of Mines and the Geological Survey on behalf on the U.S. Atomic Energy Commission was prompted by the history of past production and the many communications reporting the occurrence of monazite in this area.

Introduction: During the winter of 1951-52 the Bureau of Mines, upon the recommendation of the Geological Survey, conducted a churn drill exploration program on monazite placer deposits in the flood plains of several streams in Cleveland and Rutherford Counties in southwestern North Carolina.

From introduction: In this study on raw material sources of uranium the Southern Interstate Nuclear Board has catalogued all known occurrences of uranium and some references to thorium in a 17-state area (P1. 1). These occurrences have been evaluated as potential sources of uranium by the State Geological Surveys and the consultant group of SINB. Favorability guides have been applied to the known occurrences and recommendations have been made for future action by the states involved, federal agencies, or by industry. State recommendations are included in state-by-state summaries. The state reports were written either by personnel of the State Geological Surveys or were abstracted from State geological survey data by members of the consultant group...The purpose of this study was to compile information on and systematically assess uranium and other radioactive occurrences in the region. The SINB undertook the project because of its statutory, interstate capability as an extension of government in each of the 17 states, an arrangement that lends itself effectively to this cooperative undertaking.

From abstract: Detailed petrologic investigations were conducted at 74 anomalies that have surface radioactivities of 5 to 300 times background in the Grandfather Mountain region of North Carolina and Tennessee. One or more specimens of radioactive rock and one specimen of nonanomalous (barren) rock were taken for chemical analysis from each of the 74 sites.

From summary: A preliminary geologic investigation was conducted to determine the uranium potential of the Triassic strata in the Dan River basin system (Dan River, Danville, and Davie County Triassic basins) of North Carolina and Virginia. The pre-Triassic Inner Piedmont basement rocks adjacent to the basins were investigated as potential sources of uranium. Outcrops of Triassic and basement rocks were examined and measured for surface radioactivity by scintillometer. Representative rock and saprolite samples were collected for laboratory analyses.

From Introduction: The purpose of this report is to provide geologic and mineral resource background information useful in evaluating the uranium potential of the Raleigh 1* X 20 sheet.

From summary: A preliminary geologic investigation was conducted to determine if the Triassic sedimentary rocks of the Sanford basin and Colon cross structure in North Carolina are favorable hosts for uranium deposits. Rocks of the adjacent Carolina slate belt were also examined as a potential source of uranium

This report follows the orientation studies in the Spruce Pine, Moore, and Johnston, North Carolina areas that were conducted by the Savannah River Laboratory in preparation for a hydrogeochemical and stream sediment reconnaissance. A total of 298 sediment sites and 210 ground water sites were sampled for this study.

From abstract: Cassiterite and spodumene, of possible economic importance, occur in a belt, 24.5 miles long and 1.8 miles in maximum width, extending southwestward from Lincolnton to Grover, N. C. This belt is in the Piedmont province, an upland with an average altitude of 1,000 feet, and is readily accessible by rail and highway. The region is underlain by crystalline limestone, quartzite, schists, gneisses, and granite. The rocks strike northeast and, in most of the belt, dip steeply northwest. Most of them are deeply weathered.

From Preface: "The present account summarizes the results of a long investigation of the rocks of the Great Smoky Mountains (1946-55) by geologists of the staff of the U.S. Geological Survey, in collaboration with those of the Tennessee Division of Geology. The technical details of this investigation have already been set forth at length in professional papers of the U.S. Geological Survey. The present account contains the gist of these findings about the rocks of the mountains, and is accompanied by a map and structure sections in which the surface and underground extent of the rocks are displayed."
