The Permian Phosphate Deposits of Western United States

Description: From abstract: The Permian marine phosphorite deposits of the western United States were laid down in the Phosphoria formation and its partial stratigraphic equivalents over an area of about 135,000 square miles in Montana, Idaho, Wyoming, Utah, and Nevada. The deposits in the eastern part of the field lie on the western margin of the structurally simple North American craton.

Precambrian uranium-bearing quartz-pebble conglomerates: exploration model and United States resource potential

Description: From Introduction: "Uranium has been discovered in fluvial quartz-pebble conglomerates in most of the Precambrian shield areas of the world, including the Canadian, African, South America, Indian, Baltic, and Australian shields. Occurrences in these and other areas are shown in Figure 1.1. Two of these occurrences, the Huronian supergroup of Canada and the Witwatersrand deposit of South Africa contain 20-30 percent of the planet's known uranium reserves (Nininger, 1974). Thus it is critical that we understand the origin of these deposits and develop exploration models that can aid in finding new deposits."

Geologic Aspects of the Resource Appraisal of Uranium Deposits in Pre-Morrison Formations of the Colorado Plateau

Description: The following report covers a reconnaissance resource appraisal in pre-Morrison formations, particularly the Shinarump conglomerate, on the Colorado Plateu and adjoining regions during December of 1951. This report is preliminary in nature and the ideas are presented as a hypothesis to be tested by future work.

Stratigraphy and Geologic History of the Montana Group and Equivalent Rocks, Montana, Wyoming, and North and South Dakota

Description: From introduction: This is a progress report on regional stratigraphic and paleontologic studies of the Upper Cretaceous Montana Group and equivalent rocks in the northern part of the western interior of the United States. It presents preliminary data on the positions of strandlines during a 14-m.y. (million year) span of the Late Cretaceous as well as our interpretations of the geologic history of this period.

Cordilleran Metamorphic Core Complexes and Their Uranium Favorability: Final Report

Description: From objective and scope: The objective of this report us to provide a descriptive body of knowledge on Cordilleran metamorphic core complexes including their lithologic and structural characteristics, distribution within the Cordillera, and their evolutionary history and tectonic setting. We also examine the occurrence of uranium in the context of possibility for uranium concentration.
