This bibliography of 211 annotated references lists reports available as of June 1957. The annotations, arranged alphabetically by author, emphasize the geologic aspects of veins that contain uranium. An index map shows the location of vein deposits referred to in the annotations. Indexes are provided with entries listed according to author, geographic area, and subject. 328 SELECTED BIBLIOGRAPHIES OF URANIUM GEOLOGY area, Montana and Wyoming, and the deposits in the Dripping Spring quartzite, Gila County, Ariz. According to Nininger (1954, p. 43), as of 1954, uranium-bearing vein deposits outside the United States had yielded by far the largest part of the total world production of uranium. Most of this production was from the deposit at Shinkolobwe, Belgian Congo, and from the Eldorado mine, Great Bear Lake, Canada. The Shinkolobwe deposit since its initial development in 1921 and until 1954 probably had yielded more uranium than all other deposits together (Nininger, 1954, p. 43). Other important foreign uraniumbearing vein deposits, some of which have yielded large amounts of uranium ore, include those near Joachimsthal (Jachymov), Czechoslovakia, and adjacent areas in Saxony; the Beaverlodge district, Canada; the Cornwall district, England; the Guarda and adjacent districts in Portugal; and the deposits at Radium Hill, South Australia. Many concepts regarding the geology of uranium-bearing veins are based on studies of the foreign deposits listed above, most of which have been known for many years. In contrast to these deposits, the important uranium-bearing veins in the United States except for some in the Central City district, Colorado were discovered since the mid-1940's. The study and development of deposits in the United States are in relatively early stages, and the literature on domestic deposits has not influenced geologic thinking as much as the literature on the previously known foreign deposits. Because of the influence imparted by the literature describing the uranium-bearing veins at Joachimsthal, Shinkolobwe, and Great Bear Lake, and because many of the following annotations describing uranium-bearing veins in the United States refer to these deposits, the following selected references on these three important deposits are listed below.

Occurrences of radioactive materials in the Bald Mountain gold-mining area, northern Black Hills, South Dakota

Abstract: Although none of the occurrences are large enough to constitute ore, uranium-bear ing hydrothermal solutions were probably present during Tertiary mineralization in the Bald Mountain area and may have given rise to the carnotite-type deposits in the sediments surrounding the Black Hills.
