Paleomagnetic analysis of bimodal magmatismassociated with Tule Tank Crater, San Francisco Volcanic Field, northeastern Arizona Christina Turpin Dr. Michael Ort Northern Arizona University, Department of Geology
Background San Francisco Volcanic Field (SFVF)
Research Tule Tank Crater Pre-Matuyama (+2.6 Ma) Matuyama (2.6 Ma – 800 ka) Brunhes (800 ka - Present)
Methods Field Work Sample Collection > < Tule Tank
Lab Work Set in Plaster Drill Cut Process
Results Benmoreite Modern magnetic field Site 5.1 Site 10
Results Rhyolite Modern magnetic field Site 1.3 Site 8.2
Conclusions • Preliminary data show some consistencies with Matuyama age of eruption • Alteration of samples’ magnetization has likely occurred • Further analysis is needed before conclusions are interpreted
Acknowledgements Dr. Michael Ort, Dr. Nadine Barlow and Kathleen Stigmon, NAU/NASA Space Grant, and Arizona Space Grant Consortium for allowing me this research opportunity!!
