GeoDaze is a research symposium organized by volunteers from the Department of Geosciences that features groundbreaking research from undergraduate and graduate students. Each year, GeoDaze is made possible by generous donations from individuals and corporate sponsors. We sincerely appreciate your continued support! GeoDaze allows students to present their research to an enthusiastic audience of faculty, industry professionals, peers, and the general public. For the third year, GeoDaze is collaborating with the other departments in the School of Earth and Environmental Sciences to bring you EarthWeek. Inclusion within this celebration of scientific research promotes interdisciplinary discussion, collaboration, and exposure for all of the participating departments. A full schedule of EarthWeek events is included on page 5 of this program. We encourage you to take advantage of all that EarthWeek has to offer. This year GeoDaze is proud to present 32 oral and 27 poster presentations from Geosciences graduate and undergraduate students. The diversity of these presentations is reflective of the Department of Geosciences’ drive to integrate earth science research “from core to clouds”. They include research in economic geology, tectonics and geochemistry, geophysics, geomorphology, geoarcheology, paleoclimate, climate dynamics, paleoecology, paleontology, detrital zircon geochronology, and geoscience education. In addition, one representative from the Department of Geosciences has been selected to participate in the EarthWeek Plenary Session, “Heat in the Earth and Atmosphere”, alongside representatives from the other SEES departments. GeoDaze is proud to host Dr. David Montgomery from the University of Washington as our keynote speaker. Dr. Montgomery is internationally recognized for his research in the field of geomorphology and his critically acclaimed novels that focus on the intersection between earth science and society. We invite you to attend Dr. Montgomery’s presentation entitled “Megafloods down the Tsangpo River gorge, eastern Tibet” at 3:00 PM on Friday, April 12th in the North Ballroom. In accordance with tradition, many exciting “extracurricular” events will take place during GeoDaze. The GeoDaze slide show will surely embarrass and entertain at 4pm on Friday. Soon after, our panel of faculty judges will present awards to the best talks and posters in each session as well as the overall runner up and best talks. All attendees of GeoDaze are invited to attend the GeoDaze party. Rumor has it that the margaritas will be flowing and the sunset will be beautiful at the home of Dr. George Zandt and Dr. Susan Beck. Make sure to save some energy for the GeoDaze field trip on Saturday. This year the trip will focus on copper mining in the Tucson area and feature tours of the proposed Rosemont mine site and the operational Silver Bell mine. We would like to thank all of those that helped with organizing GeoDaze this year. Without your tireless efforts GeoDaze could not be the success it is!

The first half of the trip will be at the Rosemont Copper proposed mine site near Sonoita, AZ in the foothills of the Santa Rita Mountains. Jeff Cornoyer, Rosemont Copper geologist, will lead a driving tour on the area’s geology and the plans for the mine. The second half of the trip will be at the Silver Bell Mine in Marana, AZ. Dr. Spencer Titley and the SilverBell Geology team (Jim Lombard, Kim Wilson, and Christine Willmott) will present on the geology and mining taking place at the active mine. SCHEDULE 8:00 am- Gather in the loading dock of Gould-Simpson (NW corner of GouldSimpson building) for introduction and materials. 8:30 am- High-occupancy vans depart for Rosemont Copper Company (Rosemont) Operations near Sonoita, AZ. 10:00 am- Arrive at Rosemont and begin guided tour of Rosemont Copper Project proposed mining site. 12:00 am- Break for lunch (provided) in scenic Santa Rita Mountains near proposed mining site. 1:00 pm- Depart Rosemont for Silver Bell Mine near Marana, AZ. 2:30 pm- Arrive at Silver Bell Mine and begin guided tour with Dr. Spencer Titley. 5:00 pm- Depart Silver Bell Mine for University of Arizona. 6:00 pm- Arrive at Gould-Simpson loading dock. 17 Fieldtrip Information Transportation Each attendant will have a place reserved in a high-occupancy van or approved personal vehicle for the full fieldtrip time. Because we will be participating in guided-driving tours we would appreciate that no personal vehicles are used for the fieldtrip. Also, because we have a full day of traveling and tours, please be considerate to other fieldtrip participants and arrive on time for departure. Tours Because we will be participating in mine tours STRICT GUIDELINES about apparel must be followed. All participants must have STURDY CLOSED-TOE SHOES (hiking boots, not sneakers), LONG PANTS (cover the full leg), and LONG-SLEEVED SHIRT (no need to wear all day, but have a shirt that covers your full arm). All participants who do not show up with suitable clothing will not be allowed to participate. Additional gear such as hard hats and vests will be provided. The tour at the proposed Rosemont mining site will include an introduction/orientation at the Rosemont ranch covering geology, mineralization, future mine site plans, etc., followed by a reclamation testing site tour and a drive to the overlook of the future mine site where lunch will be provided. The tour at Silver Bell Mine will be led by Dr. Spencer Titley and will include orientation (geology, safety, etc.), followed by a driving tour to different parts of the mine to view mining operations and production. It is common to see big horn sheep at the mine site. 18
