Discussing the potential for Afghanistan to be used as a uranium source.

"The understanding of interactions between the elementary particles, which no number thirty, and range from the massless neutrino to the Е with a mass of approximately 1320 Mev, in a prerequisite to the knowledge of the structure of matter. Although the complex aggregate of elementary particles which constitute matter displays properties different from those of the basic building blocks, nevertheless it is impossible to gain a firm knowledge of the behavior of matter without first ascertaining in the intrinsic properties of elementary particles, as well as the dynamics of their interactions. The present work is concerned with inelastic proton-proton scattering at 1.35 Bev, where single pion production predominates."

From abstract: This report summarizes data of the uraniferous phosphate resources of the United States in detail and of the rest of the Free World more generally (Volume 1). It also evaluates the technical, economic, and environmental feasibility of production of uranium as a by-product, co-product, or single product from the uraniferous phosphate resources (Volume 2).

This report discusses the results of a mineral survey of the Superstition Wilderness and contiguous RARE II Further Planning Areas, Tonto National Forest, Gila, Maricopa, and Pinal Counties, Arizona.

From objectives: In the Salton Sea Quadrangle, reported uranium occurrences were evaluated, and geologic environments thought to be favorable were examined. This report includes the field data collected during that work and a summary of the quadrangle geology and uranium favorability. This is the final report to be prepared on this quadrangle under the NURE program.

Abstract: In 1958 geologists of the U.S. Atomic Energy Commission and the Instituto de Investigaciones Geológicas de Chile made a reconnaissance for uranium in the Mamiña area, Province of Tarapacá in northern Chile.

Summarizing the Observations, interpretations, and recommendations of the Authors who were assigned for a two month period to cooperate with the Colombian government in an evaluation of their uranium exploration program.

Discussing evidence of the potential of uranium in Peru

From abstract: "On the 86-inch cyclotron a 41-kw beam has been calorimetered at a net ion loading efficiency of 40%; the average proton current was 1.85 ma at 22.5 Mev. Practical specific yields have been determined for (p,2n) reactions on zinc and bismuth. The investigation of products of proton-induced fission of uranium has been continued and new techniques are being used in measuring angular distribution of reaction products. The 63-inch heavy particle cyclotron is now in operation; N+++ particles have been accelerated to ~25 Mev. In preliminary tests, induced activities have been detected in carbon, nitrogen, and oxygen targets. A hot-cathode ion source is ready for test operation. The 22-inch cyclotron is being used in an investigation of the problems associated with the use of rf and dc electrodes for the acceleration of protons from the ion source into the dees. Radiation-induced corrosion in Inconel tubing containing #21 eutectic (ANP) has been produced by proton irradiation in the 86-inch cylclotron; it is shown that the corrosion was not due to thermal effects. Approximately 150 grams of highly purified U 238 (< 5 ppm U 235) have been prepared, and two grams of thorium 230 (ionium) has been enriched to 90.6%."

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

This report is on the Hells Gate Roadless Area (3-021), Gila County, Arizona.

This technical report covers five areas: (1) High-speed computer program; (2) Mathematical methods; (3) ILLIAC use and operations; (4) IBM 650 use and operation; (5) General laboratory information.

Abstract: In August 1958 two geologists of the Instituto de Investigaciones Geológicas de Chile made a one-week reconnaissance for uranium of the Arica area in northern Chile.

Discussing a two-week reconnaissance of the Lonquimay area, in south-central Chile, in which anomalies were noted in marl and in a sulfide-mineralized shear zone in continental black shales

From operational program: This final report includes a general geologic description of the area, including descriptions of the various geologic units and correlates the airborne data to the geologic units as provided by the geologic maps. Also included is a frequency distribution study of the data as a function of the geologic units encountered over the NTMS area including the tie line data. This report also consists of a discussion of the area surveyed and includes all single record reduced data and averaged record data listings on microfiche.

Abstract: A low-level airborne radiometric survey of the younger pre-Cambrian Dripping Spring quartzite, undertaken in the mountainous region lying roughly 100 riles east of Phoenix, was completed June 3, 1955. Twenty-seven radioactive anomalies were located. To date seven of these have produced uranium ore, four more will probably become producers, and six others may possibly become producers. Flying was concentrated in the Dripping Spring quartzite, but reconnaissance flights were made over other formations. Private prospecting, both from the air and on the ground, increased considerably when the airborne project started. Eleven of the private discoveries have produced ore, and many others show considerable promise.

Abstract: The area was examined for a period of about two weeks during October and November 1958 by geologists of the U.S. Atomic Energy Commission and the Instituto de Investigaciones Geológicas de Chile for the purpose of evaluating known uranium occurrences and determining the overall potential of the region for uranium.

From purpose and scope: This report is designed to summarize the available information on the geology and ore reserves of the uranium deposits. Detailed geological work has been confined largely to those areas which contain the more promising uranium occurrences with at least 80 percent of such work being concentrated in the Sierra Ancha district.

From introduction: The parameters considered in this study are of two types: core-physics dependent, resulting from various fuel-management schemes and core-physics independent, relating to various modes of plant operation.

A progress report on the status of various projects in the area of radioactive materials and nuclear power covering the period from October to December 1954.

This quarterly progress report discusses the ongoing work within the Solid State Division at the Oak Ridge National Laboratory for the period ending August 10, 1952. Projects discussed include radiation metallurgy, engineering properties, fused salts, crystal physics, and solid state reactions.

From summary: Union Mines' examination of Arizona's pegmatites, lode deposits of the central and southeastern parts of the state, and heavy mineral concentrates from few placer deposits indicates that SOM is practically non-existent in the first two and that minor amounts of monazite and possibly other S-37 minerals are present in the last.
