Modern-Style Subduction Reflected in the 2.0 Billion Year Old East African Eclogites

板块构造是动态地球的地壳表达，过去20亿年来一直如此(Ga)。作为连接地球深处、水圈和大气层的纽带，板块构造是地球上生命的基础：它使我们有别于我们的行星邻居。然而，在地球生命的前半部分，板块构造可能并不以相同的形式存在。该项目将1)增加我们在板块构造之初对地球的了解，并促进社区对地球演化的了解；2)解决澳大利亚许多矿藏形成时地球的基本性质，从而有助于地球深层资源的勘探。

Plate tectonics is the crustal expression of the dynamic Earth, and has been so for the past 2 billion years (Ga). As the link between the deep Earth, the hydrosphere and the atmosphere, plate tectonics is fundamental to life on Earth: it is what stands us apart from our planetary neighbours. Yet, plate tectonics may not have existed in the same form for the first half of the planet's life. This project will 1) increase our understanding of the Earth at the dawn of plate tectonics and foster community knowledge of the evolving Earth; 2) address the fundamental nature of the Earth at the time of much Australian ore formation, thus assisting in deep Earth resource exploration.
