Throughout the evolution of this thesis the writer was ably counseled by Dr. Thomas E. Bates who gave much time and thought .to the study. Many aspects of this work were discussed with Dr. P. D. Krynine and Dr. J. C. Griffiths. The writer is particularly indebted to them for many discussions on the methodology of inference and scientific thinking. Many valuable suggestions and explanations were given by Dr. W. Bradley of the Illinois Geological Survey.
Miss Ethel Senkovits took the electron micrographs/ The work was supported by a grant from the Geophysics Branch of the Office of Naval Research and is part of an investigation of the morphology, structure, and origin of fine-grained minerals. <...>

The Colorado Plateau is one of the prominent uranium (-vanadium) provinces of the world. It encompasses almost 350,000 km2 in western Colorado, southern Utah, northern Arizona, and northwestern New Mexico. A great number of peneconcordant, tabular sandstone-type uranium deposits in Jurassic and Triassic formations have been discovered therein. Most deposits are clustered in districts of variable size.

An important prerequisite to the long-term use of nuclear energy is information on uranium ore deposits from which uranium can be economically exploited. Hence the basic purpose of this book is to present an overview of uranium geology and data characteristic for uranium districts and deposits in the United States of America and Latin American countries. With respect to the classification terminology of uranium deposits used in this volume, the reader is referred to the typological classification system of uranium deposits presented in Part I Typology of Uranium Deposits in the first volume of the series Uranium Deposits of the World - Asia (Dahlkamp 2009).

Without the encouragement and assistance of Dorothy Hussey, a good friend and wonderful person, I would have never undertaken this endeavor. Being literate, she knew that there is very little recorded history of a people and industry that have been so important to Western North Carolina. Thanks, Dorothy.
Without the aid of local news, newspapers and other printed material, this would have been a most difficult task. <...>

The Arkansas bauxite region lies near the center of the State in Pulaski and Saline Counties. It is irregular in outline, covering about 275 square miles and is elongate in a northeasterly direction. Bauxite deposits in the region can be grouped into two principal districts, one in Pulaski County about 5 miles south of Little Rock, and the other, more important commercially, about 25 miles southwest in Saline County.
