This week Dr. Ryan Currier, University of Wisconsin, Looks at Dry Valleys in Antarctica
- Mar 27, 2017
Dr. Ryan Currier, University of Wisconsin, Green Bay, joins us this week. His topic: "A Portrait of Crustal Melting in the Dry Valleys of Antarctica." Melt zones in the shallow crust are rarely observed. The Dry Valleys of Antarctica expose a shallow, mafic magma plumbing system, which induced melting of the surrounding granitic crust. This melt zone is small enough that it did not erupt or appreciably homogenize with mafic magma, yet large enough to record phenomena not seen in crucible-scale experiments. Results have implications for A-type granitic systems, which are thought by some to be shallow granite melts, but have yet to be observed in the act of formation. Join us for this presentation on Friday, March 31, 2017 from 12:30 to 1:30 pm in Room 204, Natural Science Building on the East Lansing.
