Did plate tectonics operate in Earth's early times - the Archaean (before 2500 million years ago)? This is important for understanding Australia's rich Archaean gold mineralisation. Using plate tectonics, young mountains like the European Alps formed when once distant continents collided. The project will investigate the origins of a deeply-eroded, superbly-exposed Archaean Greenland mountain belt and its gold mineralisation. This is to establish whether it represents a deep section through an Archaean continent-continent collision formed via ancient plate tectonics and also to provide insight into Australia's important Archaean gold deposits and to produce models to help search for more gold.

板块构造是否在地球的早期 - 古老的时代（25亿年前）？这对于理解澳大利亚丰富的古老金矿化很重要。使用板块构造，当遥远的大洲相撞时，年轻的山脉像欧洲阿尔卑斯山一样形成。该项目将调查一个深厚的，典型的古代格陵兰山带及其金矿化的起源。 这是为了确定它是否代表了通过古代大陆大陆碰撞的深度部分，该碰撞是通过古老的板块构造形成的，并且还可以洞悉澳大利亚重要的Acrathean Gold矿床，并生产模型以帮助寻找更多的黄金。
