This project aims to understand the geological controls on high-grade (>2 g/t Au) oreshoots at the world-class Wallaby gold deposit (>7 Moz Au). In particular, the role of magmatic fluids in the transport and deposition of gold will be investigated. The Wallaby gold deposit is an ideal natural laboratory to investigate the complex relationship between the geometry and timing of faults, influx of multiple hydrothermal fluid events and the deposition of gold. In particular, the study will investigate the relative importance of intrusion-related, and fault zone-related events in the formation of high-grade ore shoots. The outcomes of this study will include a clear understanding about the timing and relative contribution of magmatic and fault zone related events and their significance to the formation and geometry of high-grade oreshoots.

该项目旨在了解世界级Wallaby存款（>7 Moz Au）中高品位（>2 g/t Au）矿体的地质控制。特别是，岩浆流体在运输和沉积的黄金的作用将进行调查。Wallaby金存款是一个理想的天然实验室，研究几何形状和时间的断层，多个热液事件的流入和金的沉积之间的复杂关系。特别是，该研究将调查与侵入有关的相对重要性，断裂带有关的事件在形成高品位矿芽。这项研究的成果将包括一个清晰的认识的时间和相对贡献的岩浆和断裂带相关的事件及其意义的形成和高级别的断层的几何。
