Subduction zones are places on Earth where one of Earth?s tectonic plates slides beneath another. They are locations of intense geologic activity that pose hazards to humans, including earthquakes and volcanoes. Understanding subduction zones is critical to developing our understanding of global geochemical cycles; the formation, evolution, and composition of the Earth?s crust; global-scale mantle dynamics; the distribution of valuable natural resources in ore deposits; and numerous geological hazards including volcanic eruptions, earthquakes, and tsunamis. Processes occurring deep within subduction zones are impossible to observe directly, but there are a wide variety of rocks that have been exhumed to the Earth?s surface from deep within subduction zones. Those who study these exhumed rocks have the unique ability to inform studies of active subduction zones by ?ground-truthing? the assumptions that go into models, experiments, and interpretive geophysics and geochemistry. ExTerra represents the community of scientists involved in studies of these exhumed rocks from the subduction system. The goal of the workshop 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 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. ExTerra 2013 will focus on research themes of common interest to these groups, provide a forum for communication and interaction among scientists, promote participation in the 2013 international Goldschmidt conference, and foster collaboration among participating scientists. We will lay the groundwork for the long-term structure of ExTerra, plan and organize future field trips, and develop an infrastructure for shared sample and data collection, archiving, and distribution. The proposed workshop will incorporate 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.

俯冲带是地球上的地方，其中一个地球？一个构造板块滑到另一个构造板块之下。它们是地质活动强烈的地方，对人类构成危险，包括地震和火山。了解俯冲带是发展我们对全球地球化学循环的理解的关键;地球的形成，演化和组成？地壳;全球尺度地幔动力学;矿藏中宝贵的自然资源的分布;以及包括火山爆发、地震和海啸在内的众多地质灾害。在俯冲带深处发生的过程是不可能直接观察到的，但是有各种各样的岩石被挖掘到地球上？从俯冲带的深处。那些研究这些挖出的岩石的人有独特的能力，通过？地面实况调查模型、实验和解释性地球物理学和地球化学中的假设。ExTerra代表了参与研究这些从俯冲系统中挖掘出来的岩石的科学家社区。ExTerra 2013研讨会的目标：通过对出土地体的研究来了解俯冲作用，是围绕一套共同的科学目标来组织与俯冲作用有关的变质岩和火成岩的不同研究，以便更有效地推动学科作为一个社区向前发展。为了实现这一目标，我们将收集研究人员的社区，研究俯冲带的三种类型的折返岩石：1）俯冲板片的高压岩石，2）中下部弧壳，3）地幔楔。ExTerra 2013将侧重于这些群体共同感兴趣的研究主题，为科学家之间的交流和互动提供一个论坛，促进参与2013年国际Goldschleman会议，并促进与会科学家之间的合作。我们将为ExTerra的长期结构奠定基础，计划和组织未来的实地考察，并为共享样本和数据收集，存档和分发开发基础设施。拟议的讲习班将包括关于目前对挖掘遗骸的研究的科学介绍（讲座和海报），关于数据库和存档进展的最新情况，并将确定今后几年举行的实地论坛的地点和组织者。
