From introduction: To improve understanding of uranium mineralization of the Todilto Limestone of Late Jurassic age in the Grants district, New Mexico, the mines active in 1957 were reviewed to determine the major types of deposits. A representative example of each type was selected and mapped in great detail to establish a prototype. It was hoped that the analysis of prototypes might shed considerable light on the mineralization process and aid evaluation of other deposits by offering a standard of comparison.

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.

This book presents reconnaissance reports for uranium deposits in Mohave County, Arizona from 1952 to 1956.

Appendix containing field data and chemical analyses of ground and surface water samples to accompany a report on U.S. uranium resources in the Ekalaka Quadrangle in Montana, North Dakota, and South Dakota.

From Purpose and Scope of Report: This report presents a detailed description of the ore deposits of the Picher field and all phases of geology having a bearing on their localization, origin, and the search for them. It is based mainly on work done by the U.S. Geological Survey, but it also incorporates pertinent data from published literature, especially from the outstanding work of George M. Fowler and associates, and some unpublished data obtained from the geologic staffs of the mining companies.

Report describing the results of studies meant to provide "determination of the most functional and economical location for a lock in the vicinity of Buffalo, N. Y., and evaluation of navigation conditions at the entrance to an overland canal joining the American channel of the Niagara River northwest of North Tonawanda, N. Y." (p. ix).

This report describes the results of a series of tests on soil borings taken in Atchafalaya Test Section VI, a 2000-ft-long portion of the Atchafalaya Basin Protection Levee System in south-central Louisiana. The samples were tested to interpret the depositional layers in the foundations soils and to determine various engineering properties.

Report issued by the Bureau of Mines on the geochemical anomalies found in the gold-antimony deposits near Stibnite, Idaho. Many samples were collected and tested through an atomic absorption method. This report includes a map.

Report issued by the Bureau of Mines on the copper deposits in the Permian red beds from north-central Texas through Oklahoma, and into southwestern Kansas. Geologic and economic properties of the copper ore are documented. This report includes tables, maps, illustrations, and photographs.

Abstract: Geologic field reconnaissance and geophysical evaluation of eight areas in the western part of the United States were made to locate a site for conducting tests of a prototype hard rock silo (HRS).

Abstract: The report describes the results of an experimental study involving the injection of a gaseous secondary jet into an unbounded supersonic flow field which was uniform outside of a turbulent boundary layer. The investigation was principally concerned with the formulation of the shock wave shapes and streamline patterns to be associated with typical turbulent, two-dimensional jet-interaction flows. In support of this objective, results are presented for a Mach 5 test conducted using a flat-plate model containing a sonic secondary jet directed normal to the main-stream. The jet-interaction flow field was primarily investigated for jet strengths (ratio of jet gas stagnation pressure to free-stream static pressure) of 180 and 550. Intermediate strengths were also studied but in lesser detail. Local flow properties were measured throughout the flow field and surface pressure distributions were recorded fore and aft of the secondary jet. From these data and complementary shadowgraph studies, the streamline pattern and attendant shock structure were formulated.

Second volume of a report documenting a high-sensitivity airborne radiometric and magnetic survey of the Salina quadrangle including a detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation maps, flight line and geologic base map, and individual corrected profiles.

From Summary and Conclusions: "After a period of tests at the Oak Ridge National Laboratory in 1966 and 1967, the Vertical Tube Evaporator (VTE) Pilot Plant was moved to the OSW's East Coast Test Station at Wrightsville Beach, N.C. In the summer of 1967 it was installed and was started in upflow operation with seawater feed, using stem and other services provided by the station. The operation of the Pilot Plant at Wrightsville Beach was performed by Stearns-Roger Corporation under subcontract to ORNL. Operation was in the upflow mode during the entire reporting period."

From Introduction: "This report covers the work done in fiscal 1970 and the small amount of work done in the early part of fiscal 1971; the inclusive dates covered are July 1, 1969 through July 10, 1970. A four effect VTE train operating in the downflow mode. A single effect VTE unit operating in the downflow mode. A mixed phase high pressure water and steam jet compression unit complete with a boiler to supply high pressure motive steam."

Purpose and Scope: "The purpose of this study is to provide basic water supply data needed for future evaluation and selection of promising saline water conversion opportunities. This report presents information regarding the present and future supply situation of individual communities. Also presented is information on regional water plans with respect to provisions for municipal water supply."

From Introduction: "This report covers the information resulting from these tasks and additionally the solution to a serious difficulty in obtaining stable operation and reasonable distillate purity due to foaming and priming which was much more serious in three stage test device than it had been in the original two-stage unit."

From Summary: "This report summarizes the down-flow heat transfer performance of enhanced surface tubes and operations at the four-effect Vertical Tube Evaporator Pilot Plant at the Office of Saline Water East Coast Test Station, Wrightsville Beach, North Carolina. The period from July 1, 1968 to June 30, 1969 is covered in this report."
