  • DOCTOR of PHILOSOPHY (Ph.D.)
    Establishing a Tephrochronologic Framework for the Middle Permian (Guadalupian) Type Area and Adjacent Portions of the Delaware Basin and Northwestern Shelf, West Texas and Southeastern New Mexico, USA A dissertation submitted to the Graduate School of the University of Cincinnati In partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY (Ph.D.) In the Department of Geology Of the McMicken College of Arts and Sciences 2011 by Brian Lee Nicklen B.S. University of Nebraska-Lincoln, 2001 M.S. University of Cincinnati, 2003 Committee Members: Prof. Warren D. Huff (Ph.D.), Chair Prof. Carlton E. Brett (Ph.D.) Prof. Attila I. Kilinc (Ph.D.) Prof. J. Barry Maynard (Ph.D.) Dr. Gorden L. Bell Jr. Prof. Scott D. Samson (Ph.D.) Abstract DesPite being recognized for many years, bentonites in the Middle Permian (Guadalupian Series) type area of west Texas and southeastern New Mexico, have received little research attention. As these important dePosits act as geologic timelines, they can be used as tools for long distance stratigraphic correlation and high-precision radioisotopic age dating. An important Problem that these bentonites can address is the lack of temporal control for the Guadalupian. This is an important time interval for significant changes in Earth’s climate and biodiversity that include events leading uP to, and Potentially including, the first pulse of a double-Phase mass extinction at the end of the Paleozoic. Also needed is better temporal constraint for key GuadaluPian global chemostratigraPhic and geomagnetic markers. In light of this, the duration of the Guadalupian stages and boundary age estimations need to be updated in order to assess cause and effect of these significant events.
