A multi-proxy provenance approach and depositional age constraints for the Upper Cretaceous Beaverhead Group, Southwest Montana

Abstract

I owe much gratitude to my colleague and friend, Justin Rosenblume, who worked his hardest this past summer to help me with my field work in Montana, around-the-clock sample processing, and analysis in Arizona. The many hours of discussion and working together tirelessly on this project are something I will always be grateful for. Thanks also to Berkley Grimm for his help with sample processing and analysis, and to the staff at the Arizona LaserChron Center for their attentiveness. I have much appreciation for the many great friends I have made here these past couple years and their emotional support and friendship, namely the very small group I arrived in Iowa City with last Fall (Justin, Tanner, Larkin, and Reuben). Many thanks to my undergraduate advisor, Dr. David Malone, for the continued support and for helping me realize how powerful detrital zircons are. Thanks to my wonderful parents, Dana Garber and Lola Arnett, for the unconditional love and support that got me where I am today. Finally, thank you to Scott Grube, who has been my rock (pun intended) through all the good and bad during my time as a graduate student and supportive and loving every step of the way.
