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区内的表现。俯冲是板块构造理论的中心租户，该项目将测试假设岩石可能会被困在巨型长寿命涡流中，这些涡流在俯冲区内循环材料。这个国际协作项目将获得有关时间尺度岩石可能仍在俯冲带中的俯冲区域内的新知识。我们将使用此信息作为俯冲区行为数值模拟的框架。该项目将在培训新一代地球科学家，并扩大公众对基本地球科学的认识方面提供重大好处。
