Factors Contributing to the Formation of Sheeting Joints
FACTORS CONTRIBUTING TO THE FORMATION OF SHEETING JOINTS: A STUDY OF SHEETING JOINTS ON A DOME IN YOSEMITE NATIONAL PARK A THESIS SUBMITTED TO THE GRADUATE DIVISION OF THE UNIVERSITY OF HAWAI„I AT MĀNOA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTERS OF SCIENCE IN GEOLOGY AND GEOPHYSICS AUGUST 2010 By Kelly J. Mitchell Thesis Committee: Steve Martel, Chairperson Fred Duennebier Paul Wessel Keywords: sheeting joints, exfoliation joints, topographic stresses, curvature, mechanics, spectral filtering, Yosemite Acknowledgements I would like to extend my sincerest gratitude to those who helped make this thesis possible. Thanks to the National Science Foundation for funding this research. Thank you to my graduate advisor, Dr. Steve Martel, for your advice and support through the past few years. This has been a long and difficult project but you have been patient and supportive through it all. Special thanks to my committee, Dr. Fred Duennebier and Dr. Paul Wessel for their advice and contributions; without your help I do not think this project would have been possible. I appreciate the time all of you have spent discussing the project with me. Thank you to Chris Hurren, Shay Chapman, and Carolyn Parcheta for your hard work and moral support in the field; you kept a great attitude during the field season. Special thanks to the National Park Service staff in Yosemite, particularly Dr. Greg Stock and Brian Huggett for their assistance. I wish to thank NCALM, Ole Kaven, Nicholas VanDerElst, and Emily Brodsky for LIDAR data collection. Thank you to Carolina Anchietta Fermin, Lisa Swinnard, and Darwina Griffin for their moral support. -
