Abstract
According to the University of New Mexico's Office of Graduate Studies, this dissertation follows a hybrid format; the chapters were written as manuscripts to be submitted to peer-reviewed journals. Chapter 1 was published in the journal Quaternary Research (May, 2011) and chapters 2 and 3 will be submitted to appropriate journals soon after this dissertation is published. Chapter 1 announces new age determinations for previously unstudied topographically-controlled eolian deposits and older ages for sand sheets than were reported by previous investigators. Chapter 2 focuses on the distribution, age, and geomorphic implications of topographically-controlled eolian deposits on Black Mesa. Chapter 3 describes the role of advanced soil profile development on the stability of eolian systems; a factor generally overlooked by researchers interested in quantifying the relative activity of sand dunes. Appendix A contains the results of tests that determine the efficacy of samples used in optically stimulated luminescence dating in all three manuscripts.
