GeoDaze is run by the graduate students in the Department of Geosciences of the University of Arizona, and is funded by the generosity of private donations. GeoDaze gives students an extremely valuable opportunity to share their research with a broad audience and receive feedback from faculty, industry and government representatives, and their peers. We are proud to offer a program at this year’s symposium that features over 70 presentations that will showcase the diverse research interests of earth science graduate and undergraduate students at the University of Arizona. GeoDaze is part of Earth Week, a series of earth science related symposiums sponsored by the School of Earth and Environmental Sciences (SEES). We are excited to be a part of this tradition and welcome students and faculty from the other SEES departments to our seminar. Student presentations will occur on Thursday, March 31st and Friday, April 1st, and cover a wide variety of topics, including: economic geology, structural geology, seismology, geodesy, planetary geology, paleoclimatology, biogeochemistry, geomorphology, archaeological geology, geochemistry, geochronology, and tectonics. We would like to extend a very special welcome to Dr. Peter Molnar, this year’s keynote speaker. Dr. Molnar is a Professor of Geological Sciences at the University of Colorado at Boulder and a Fellow at the Cooperative Institute for Research in the Environmental Sciences. His research focuses on understanding how mountain ranges form and continental lithosphere deforms, as well as the relationships between the tectonic evolution of the Earth and climate change. Dr. Molnar will speak at 3:15 PM on Friday, April 1st. His talk is entitled Mantle Dynamics and the Rise and Fall of Mountain Belts. On Friday, April 1st we will honor several individuals with special recognition, announce the student awards, and, of course, view the (in)famous annual GeoDaze slide show. Friday evening, we encourage everyone to attend the annual GeoDaze party, which will be held at the residence of Dr. Susan Beck and Dr. George Zandt. On Saturday morning, we will depart for the Santa Rita Mountains on a field trip led and designed by Dr. Charles Ferguson from the AZGS. This year’s fieldtrip will focus on the volcanology near Mt. Wrightson, but will also discuss implications to regional and structural geology. The trip departs from the loading dock on the North side of the Gould-­‐Simpson Building at 8:00 AM. GeoDaze is an important tradition for our department, and we would like to thank everyone who has contributed to making it a success. GeoDaze would not be possible without the hard work and dedication of the faculty, students and staff in the Department of Geosciences and the generous financial support of the department’s alumni, friends, and corporate sponsors. We are honored to be part of such a wonderful community of people who engage in and support geoscience research. Thank you for attending this year’s GeoDaze Symposium, and we hope to see you in the years to come!

Leader: Dr. Charles Ferguson of the Arizona Geological Survey Pre-­‐trip Info Session: 8:15AM Friday, April 1 Registration Deadline: 5:00PM Monday, March 28 Field Trip: 8:00AM – 4:30PM, Saturday, April 2. Meet at 8:00AM. Leaving from the Gould-­‐Simpson loading dock. Box lunch provided. Participants should bring ample sunscreen and water. Description: This year’s trip will travel to the Sawmill Canyon fault zone at the western base of the Santa Rita Mountains. We will examine key relationships there to evaluate 1) the nature of the contact; 2) the age of Mount Wrightson Formation; 3) the origin of the Mount Wrightson Formation. New results of mapping by the AZGS will be presented, which will hopefully generate some lively discussion surrounding Mount Wrightson and the regional geology of SE Arizona. P a g e | 17
