This project aims to unravel the tectonic origin and economic potential of ultramafic rocks (rocks which host elevated concentrations of nickel, cobalt, chromium, and platinum-group elements). Such rocks are outcropping in eastern Australia along a contorted ~1500 km long belt that may record relics of an ancient ocean. Through detailed mapping and cutting-edge analytical techniques, the project is expected to fill a crucial knowledge gap in Australian tectonics, while providing information on ore mineralisation. The expected outcomes, including new tectonic models unveiling the scale, geometry, and economic potential of the ultramafic bodies, could benefit critical mineral exploration, carbon storage solutions, and geoecology conservation.

该项目旨在揭示超镁铁岩（含有高浓度镍，钴，铬和铂族元素的岩石）的构造起源和经济潜力。这些岩石在澳大利亚东部沿着一条扭曲的~1500公里长的带出露，可能记录了一个古老海洋的遗迹。通过详细的测绘和尖端的分析技术，该项目有望填补澳大利亚大地构造学的一个关键知识空白，同时提供有关矿石矿化的信息。预期的成果，包括揭示超镁铁岩体规模、几何形状和经济潜力的新构造模型，可能有利于关键的矿产勘探、碳储存解决方案和地质生态保护。
