What goes on inside subduction zones?

这个项目旨在破译岩石在俯冲带内的行为。俯冲作用是板块构造理论的核心组成部分，该项目将检验岩石可能被困在巨大的长期涡流中的假设，这些涡流在俯冲带内循环物质。这一国际合作项目将利用俯冲岩石的压力-温度-年龄限制，产生关于岩石可以被困在俯冲带内的时间尺度的新知识。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带来重大好处。

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.
