Field Trips GSA219

by | Jun 18, 2019 | Uncategorized

Plan now to take advantage of these unique trips as part of your GSA 2019 experience. https://community.geosociety.org/gsa2019/learn/field 14. Tectonic Development of the Colorado Plateau Transition Zone, Central Arizona: Insights from Lower Crustal and Mantle Xenoliths and Volcanic Host Rocks. Sat., 21 Sept. Cost USD $240. Cosponsors: GSA Geochronology Division; GSA Mineralogy, Geochemistry, Petrology, and Volcanology Division; GSA Structural Geology and Tectonics Division.Leaders: Alan D. Chapman, Macalester College; Nancy Riggs; Mihai N. Ducea. Trip Description This one-day outing will showcase Late Oligocene to Quaternary volcanic rocks and entrained lower-crustal and mantle xenoliths of the Transition Zone between the Colorado Plateau and the Basin and Range, as these materials provide key constraints on the tectonic evolution of the region. Important themes to be examined include (1) the growth, tectonic displacement, and foundering of sub-orogenic plateau (i.e., Nevadaplano) root material; and (2) the interplay between deep crust/upper mantle processes, late Cenozoic magmatism, and metamorphic core complex development. Primary Leader Email Address: chapman@macalester.edu Key qualifications: I’ve been engaged in NSF-funded study of the xenolith localities to be visited since 2015. I have been leading professional (e.g., a GSA Cordilleran Section Meeting trip in 2016), teaching, and outreach field trips for over a decade. Phoenix, Arizona, is an ideal central location from which to run this trip. All locations to be visited are within 1.5 hours’ drive from Phoenix. Professional preparation and appointments: University of Minnesota, B.S., 2005; California Institute of Technology; Ph.D., 2011, University of Arizona; Postdoctoral Researcher 2011–2013 Stanford University; Postdoctoral Researcher 2013–2014 Missouri S&T; Asst. Prof. of Geology 2013–2015 Macalester College; Asst. Prof. of Geology 2015. Relevant experience: Completed two three-week field...
