All other material © 2015 Michael E. Dittes All Rights Reserved. ACKNOWLEDGMENTS I would like to extend my thanks to those, who without their help I would not have been able to bring this project to completion. First and foremost, I thank Professor Joseph Labuz who took a chance on me, by offering me a TA-ship. Through my time in school, Joe helped me stay focused when I started to move off on tangents, offered timely advice, and over the years has become much more than my advisor. I am proud to think of him as a friend. Professors Andrew Drescher and Peter Huddleston also deserve special thanks for providing critical review of my work, and agreeing to sit on my thesis committee. To Ms. Tiffany Ralston who had an uncanny way of knowing what I needed to do, and how, before I knew myself. To Charles Nelson who helped me streamline my thesis project and helped me gain access to the Minnesota Library Archives construction site. To my fellow graduate students with whom I debated, joked and laughed, you helped me see things that I was missing. Your input was invaluable and you have my deep appreciation. -

ABSTRACT OF THESIS STRUCTURAL GEOLOGY OF THE TRANSYLVANIA FAULT ZONE IN BEDFORD COUNTY, PENNSYLVANIA Transverse zones cross strike of thrust-belt structures as large-scale alignments of cross-strike structures. The Transylvania fault zone is a set of discontinuous right-lateral transverse faults striking at about 270º across Appalachian thrust-belt structures along 40º N latitude in Pennsylvania. Near Everett, Pennsylvania, the Breezewood fault terminates with the Ashcom thrust fault. The Everett Gap fault terminates westward with the Hartley thrust fault. Farther west, the Bedford fault extends westward to terminate against the Wills Mountain thrust fault. The rocks, deformed during the Alleghanian orogeny, are semi-independently deformed on opposite sides of the transverse fault, indicating fault movement during folding and thrusting. Palinspastic restorations of cross sections on either side of the fault zone are used to compare transverse fault displacement. -
