I’m still going to try, but I apologize in advance for any omissions. First, I would like to thank my advisor, Andy Freed, and the rest of my Ph.D. committee: Jay Melosh, Marc Ca↵ee, and Brenda Bowen. You all have been of enormous assistance in guiding my studies, providing feedback on what’s important, and teaching me how to be a productive member of the scientific community. There have also been numerous other scientists who have helped me over the years. Among these are Steve Hauck, my undergraduate advisor and the man who recom- mended I take a look at Purdue; Sean Solomon, who has always been positive and supportive of my work and who generously invited me into the messenger sci- ence community; Paul Byrne, Christian Klimczak, and Shoshana Wieder, the Three Musketeers (or Stooges, depending on the day) of messenger science team meet- ings, who are all truly excellent companions and mentors; Kathleen Howell, who has been an encouraging and instructive co-leader of the lava tube working group; David Kring, who led the field camp I attended at Meteor Crater and who, despite that, later accepted my application for a summer internship at LPI; Tom Watters, who helped teach me about Mercurian geology; and Maria Zuber, whose feedback on my grail-related work has always been extremely helpful. My fellow Purdue graduate students (some current, some former) have also gener- ally made Purdue University a wonderful place to spend all this time, as well as helping me grow both professionally and personally. Honestly, everyone who I’ve spent time with over the past six years deserves mention, including every single person who has attended our “Crater Caf´e” planetary science group and “GaGgle” geology and geo- physics group. There have been many other people who have made Lafayette great, iv too, including many of Cassie’s coworkers and every barista at Caf´eRoyale. Since Idon’thavespaceforthat,though,I’dliketoextendaspecialthankstoBrandon Johnson, Alexandria Johnson, Tim Bowling, Patrick Brennan, Jon Buzan, Christy Gibson, Tommy Lovell, Mallie Rydzik, Erica Erlanger, Heather Houlton, Sheridan Ackiss, Ruth Arono↵, Darryl Reano, Aaron Goldner, Loic Chappaz, Rohan Sood, Colleen Milbury, Lutfi Shakor, and Wasim Almakki, for their friendship and conver- sations over the years. An extra special thanks goes to all of the people with whom I’ve had the good fortune to share HAMP 3261 (n´ee CIVL 3261) with over the years: chronologically, that’s Syed Tabrez Ali (thanks for teaching me VIM!), Tonya Richardson (“wait, you don’t know about...”), Melissa McMullen (I will watch your cat any time), Haylee Dickinson (who always makes me laugh), Steeve Symithe (a Grillot for life now), Roby Douilly (a GMT god), Chen Chen (whose taste in restaurants is impeccable), Josh Boschelli (who’s slowly turning me into a Marvel guy), and Liesl Elison (whose new baby is adorable). My interactions with Hersh Gilbert have also largely been in the context of that room, and over the years he’s provided invaluable advice both scientific and velocipedic. Iofcoursewouldn’tbeherewithoutthesupportofmyparents,mygrandparents, and my mom- and dad-in-law. They’ve always encouraged me to reach higher, stay sane, do what interests me, and, above all, be happy. Thank you Mom, Dad, Theresa, Tony, Grandma Blair, Grandpa Blair, and Grandma Lynch, for absolutely everything. Nor could I have asked for better or more supportive siblings, who keep reminding me both that I can do whatever I set out to do, and that there’s more to life than graduate school. Thank you Kate, Daniela, Max, Deb, Dannielle, Todd, Jennifer, and Chelsey. And finally, I wouldn’t be writing this at all without all the love, friendship, support, and encouragement that my wife, Cassie Grillot, has given me over the years. You’re my big and little spoon, now and always. Thank you more than I can possibly express. v TABLE OF CONTENTS Page LIST OF TABLES ................................ vii LIST OF FIGURES ............................... viii ABBREVIATIONS ................................ xv ABSTRACT ................................... xvi 1 INTRODUCTION .............................. 1 1.1 Document Structure .......................... 2 1.2 Chapter Summaries ........................... 3 1.2.1 Chapter 2 Summary and Context ............... 3 1.2.2 Chapter 3 Summary and Context ............... 5 1.2.3 Chapter 4 Summary and Context ............... 7 1.2.4 Appendix A Summary and Context .............. 10 1.2.5 Appendix B Summary and Context .............. 10 2 THE ORIGIN OF GRABEN AND RIDGES IN RACHMANINOFF, RA- DITLADI, AND MOZART BASINS, MERCURY ............. 11 2.1 Abstract ................................. 11 2.2 Introduction ............................... 12 2.3 Observational Constraints ....................... 16 2.3.1 Extent and Origin of Smooth Plains Material ........ 16 2.3.2 Distribution and Size of Tectonic Features .......... 18 2.4 Modeling Approach ........................... 19 2.5 Evaluation of Candidate Mechanisms ................. 23 2.5.1 Thermal Contraction of Smooth Plains Material ....... 23 2.5.2 Uplift of the Basin Floor .................... 28 2.5.3 Subsidence Due to Volcanic Loading ............. 31 2.6 Discussion ................................ 33 2.6.1 Implications of Thermal Contraction: A Step in the Sub-Volcanic Basin Floor ........................... 35 2.6.2 Implications of Thermal Contraction: A Thick Volcanic Cool- ing Unit ............................. 36 2.6.3 Implications of Thermal Contraction: Late-Stage Volcanic Flows 37 2.7 Conclusions ............................... 38 2.8 Acknowledgements ........................... 40 vi Page 3 DETERMINING THE STRUCTURAL STABILITY OF LUNAR LAVA TUBES .................................... 41 3.1 Abstract ................................. 41 3.2 Introduction ............................... 41 3.3 Modeling Techniques .......................... 44 3.4 Results .................................. 49 3.5 Discussion ................................ 57 3.6 Conclusions ............................... 60 3.7 Acknowledgements ........................... 61 4 THE GEOPHYSICAL HISTORY OF ORIENTALE BASIN ....... 63 4.1 Abstract ................................. 63 4.2 Introduction ............................... 64 4.3 Observational constraints ........................ 67 4.4 Modeling approach ........................... 69 4.4.1 Hydrocode modeling ...................... 70 4.4.2 Finite element modeling .................... 72 4.4.3 Gravity calculation procedure ................. 77 4.5 Results .................................. 78 4.5.1 Hydrocode results ........................ 79 4.5.2 Finite element modeling results ................ 83 4.6 Discussion ................................ 89 4.7 Conclusions ............................... 93 4.8 Acknowledgements ........................... 94 REFERENCES .................................. 95 A CALCULATION OF GRAVITY OVER A RING ............. 109 B GRAVITY CALCULATION CODE: GRAV ANOMALY.PY ....... 113 VITA ....................................... 142 vii LIST OF TABLES Table Page 2.1 Styles of Faulting Predicted From the Relative Magnitude of the Principal Stress Componentsa ............................ 20 2.2 Model parameters .............................. 23 3.1 Model parameters .............................. 47 4.1 Hyrdocode model parameters ....................... 71 4.2 Finite element model parameters ..................... 74 viii LIST OF FIGURES Figure Page 2.1

The spacecraft was landed in the northwest of the Procellarum KREEP Terrane (43.0576◦N, 308.0839◦E) on 1 December 2020 and returned 1731 g samples from a previously unvisited region. The landing area has been proposed as one of the youngest mare basalt units of the Moon and holds important information of lunar thermal evolution and chronology. However, the absolute model ages estimated in previous studies are quite different, ranging from 2.07 Ga to 1.21 Ga. Such significant difference may be caused by (1) different crater counting areas, (2) different crater diameter ranges, (3) effects of secondary craters, and (4) biases in crater identification. Moreover, the accurate landing site was unknown and the ages were estimated over the Eratosthenian-aged mare unit (Em4) instead. In light of the above unsatisfactory conditions, this study seeks to establish a standard crater size-frequency distribution of the CE-5 landing site.
