The goal of ExTerra 2013: Understanding Subduction through Studies of Exhumed Terranes is to organize disparate studies of subduction-related metamorphic and igneous rocks around a common set of scientific targets, and using centralized tools, in order to move the discipline forward more efficiently as a community. In order to accomplish this goal, we will gather the communities of researchers investigating three categories of exhumed rocks from subduction zones:
1) high-pressure rocks of the subducted slab,
2) middle and lower arc crust, and
3) the mantle wedge.
The ExTerra 2013 workshop will be held starting in the morning of Saturday, August 24, lasting through the middle of Sunday, August 25, during the two days prior to the 2013 Goldschmidt Conference in Florence, Italy. It will be held in classrooms on the campus of the University of Florence. The program will include scientific presentations (talks and posters) on current research in exhumed terranes, an update on database and archiving progress, and will identify localities and organizers for field forums to be held over the next few years.

General discussion and wrap-up
On August 24-25, 2013, geoscientists met in Florence, Italy for the ExTerra 2013 workshop prior to the Goldschmidt conference. In all, there were 33 participants from 9 countries, including 11 students, 2 post-docs, and 5 early-career faculty. Workshop participants divided into three groups based on different types of exhumed terranes: subducted slab, mantle wedge, and arc crust. The groups were tasked with refining the key scientific questions previously identified in the ExTerra White Paper (2012) and discussing future directions for ExTerra.
