Deep Crustal Section Through a Late Archaean Orogen (Greenland): Archaean Crustal Sutures, Abyssal Peridotites and Gold. 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.

晚太古代造山带(格陵兰)的地壳深部剖面：太古代地壳缝合带、深海橄榄岩和金矿。板块构造在地球早期--太古宙(2.5亿年前)活动吗？这对于理解澳大利亚丰富的太古代金矿很重要。利用板块构造，像欧洲阿尔卑斯山这样的年轻山脉是在曾经遥远的大陆相撞时形成的。该项目将调查一条被深度侵蚀、高度暴露的太古代格陵兰山脉带的起源及其金矿作用。这是为了确定它是否代表了通过古代板块构造形成的太古代大陆-大陆碰撞的深部，并提供了对澳大利亚重要的太古代金矿床的洞察，并制作了有助于寻找更多金矿的模型。
