This project aims to decipher how rocks behave inside subduction zones. Subduction is a central tenant of plate tectonic theory and the project will test the hypothesis rocks can become trapped within giant long-lived eddies that circulate material within subduction zones. This international collaborative project will generate new knowledge regarding the time scales rocks can remain trapped inside subduction zones using pressure–temperature–age constraints from subducted rocks. We will use this information as a framework for numerical simulations of subduction zone behaviour. The project will provide significant benefits in training a new generation of Earth scientists, and in broadening public awareness of fundamental Earth science.

该项目旨在破译岩石在俯冲带内的行为。俯冲是板块构造理论的核心内容，该项目将测试岩石可能被困在俯冲带内循环物质的巨大长寿漩涡中的假设。这个国际合作项目将产生关于时间尺度的新知识，岩石可以使用俯冲岩石的压力-温度-年龄限制被困在俯冲带内。我们将使用这些信息作为俯冲带行为的数值模拟的框架。该项目将在培训新一代地球科学家和扩大公众对基础地球科学的认识方面产生重大效益。
