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现，在过去的20亿年里一直如此（Ga）。板块构造作为地球深部、水圈和大气层之间的联系纽带，对地球上的生命至关重要：它使我们有别于我们的行星邻居。然而，板块构造在地球生命的前半期可能并不以同样的形式存在。该项目将1）增加我们对板块构造初期地球的了解，并促进社区对不断演变的地球的了解; 2）解决澳大利亚许多矿石形成时地球的基本性质，从而协助地球深部资源勘探。

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.
