Geology of Lukachukai Mountains Area, Apache County, Arizona

Description: From introduction: The purpose of this paper is to present the geologic facts which have been discovered thus far about the Lukachukai area and to draw conclusions about uranium mineralization. Basic data of general nature are included to facilitate the work of future geologists in this area who may find the information applicable to new ideas.

The Occurrence of Uranium in the Diamond Head Group, Sierrita Mountains, Pima County, Arizona

Description: Abstract: The Diamond Head droup area is entirely igneous. Tight fractures in alaskite and granite, which have been altered by heiratite and kaolinization contain narrow seams and very locally,pods of sooty uraninite. A greater percentage of the structures in the area strike about east-west and dip steeply to the north, while the radioactive structures have similar strike, they dip steeply to both the north and the south. A drift has been driven on a mineralized structure far enough to ascertaiā€¦ more

Uranium in Peru

Description: Introduction: From the inception of the effort to utilize atomic energy PerĆŗ has been of interest as a possible source of radioactive raw materials because of its great variety and abundance of metals. Because of this and a desire at that time to develop additional supplies of uranium, a cooperative program to search for uranium deposits was initiated in 1953 by the Junta and the USAEC.

Reconnaissance for Uranium in the Chanaral-Taltal area, Provinces of Antofagasta and Atacama, Chile

Description: Abstract: In the ChaƱaral-Taltal area of northern Chile irregular replacement type iron deposits are especially well developed along a somewhat radioactive lithologic belt in andesite volcanic rocks and Cretaceous dioretic intrusions to the east of the Atacama fault, a prominent shear zone.

Reconnaissance for Uranium in the San Pedro de Atacama and Laco areas, Province of Antofagasta, Chile

Description: Abstract: A reconnaissance for uranium in and a general geologic study of the San Pedro de Atacama and Laco areas of nothern Chile disclosed no significant radioactivity in the Laco area, but near San Pedro de Atacama slight anomalies were detected in limey silts of the San Pedro formation.

Geology and Uranium Deposits of the Carrizo Mountains Area Apache County, Arizona and San Juan County, New Mexico

Description: Although uranium gas first discovered in the Carrizo Mountains area in 1918, the ores were not developed until 1942. They have, however, been mined continuously since that time. Formations in the area range from the Pernian Cutler through the Cretaceous Mancos shale, and all are intruded by a dioritic laccolith and its related dikes. The older structures, which include the Defiance Uplift, the San Juan Basin, and the Four Corners Platform are somewhat disrupted by the effects of the intrusion. ā€¦ more

Geology and Uranium Deposits of the Carrizo Mountains Area Apache County, Arizona and San Juan County, New Mexico

Description: From Purpose, Scope, and Methods: The objective of this study was an evaluation of resources of the Carrizo Mountains area. Four factors: distribution of ore bodies, relation of uranium to the host rock, relation of ore to structure, and circumstances that might precipitate uranium were studied in search of data bearing on manner of distribution of ore, the time and causes of deposition, and the probable source of the uranium-bearing solutions.

Geology of the Uranium Deposits of the Lukachukai Mountains Area Apache County, Arizona

Description: Abstract: In a study of the comparative importance of sedimentary and tectonic ore controls and in search of data bearing on the origin of the deposits, ten mines in the Lukachukai Mountains, Apache County, Arizona were examined in detail. All commercial deposits in the area are in the Salt Wash Member of the Morrison Formation of Jurassic age. The ore bodies are elongate and horizontally lenticular in shape and consist of one or more ore pockets surrounded or separated by protore. The compositā€¦ more

Preliminary Report on Uranium Occurrences on the Yuma Test Station Yuma County, Arizona

Description: From introduction: This report is written in response to a request from the Army Engineers for an appraisal of the uranium potential of the area included in the Yams Test Station. the area of Proposed Expansion of the Yuma Test Station, and the Williams Bombing and Gunnery Range. Only the area covered by the present Yuma Test Station is included here. The other areas will be discussed In subsequent reports.

Final Report: Airborne Reconnaissance Project Dripping Spring, Quartzite, Gila County, Arizona

Description: 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 oā€¦ more

Geology of Uranium Deposits in Tertiary Lake Sediments of Southwestern Yavapai County, Arizona

Description: From purpose and scope: and primary objective was to determine the extent and grade of ore present and the future potential of the district. The second and broader objective was to learn the relationship of ore to stratigraphy and structure, in order to outline similar areas favorable for prospecting.

Airborne Reconnaissance in Southwestern Arkansas

Description: Introduction: Reconnaissance for uranium in central and southwestern Arkansas was carried out as a joint project of the U.S. Atomic energy Commission and the U.S. Geological Survey during March and May 1954. The project was planned as an investigation of several areas of known abnormal radioactivity, and as a search for others, by airborne and ground radiometric reconnaissance.
