V11E:
Oceanic Arcs and the Evolution of Crust: Results from IODP Expeditions to the Izu-Ogasawara-Mariana Arc System and Other Advances from Pacific Island Arcs I

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 18140

Session Description:
Several expeditions to Pacific subduction systems have taken place over the past few years. Examples include the IODP Expeditions 350, 351 and 352, which explored the northern IBM (Izu-Ogasawara-Mariana) system, and the GeoPRISMS-related expeditions to the Aleutian Islands. Now is the time for early results to be presented and for discussions to occur between the scientific teams working in these diverse systems.  Studies exploring petrology, geochemistry, geophysics, geochronology, and geodynamics of these regions are welcome. Also welcome are explorations of the links between oceanic island arcs and the development of continental crust.
