Geological controls on high-grade oreshoots in the Wallaby gold deposit, Western Australia: Understanding the role of magmatic fluids in an Orogenic Au system.

该项目旨在了解世界级袋鼠金矿床(&gt；7Moz Au)高品位(&gt；2g/t Au)矿体的地质控制。特别是，将研究岩浆流体在金的运输和沉积中的作用。Wallaby金矿床是研究断裂几何形状和时间、多种热液事件的涌入和金的沉积之间复杂关系的理想天然实验室。特别是，这项研究将调查与侵入相关的事件和与断裂带相关的事件在高品位矿脉形成中的相对重要性。这项研究的结果将包括清楚地了解岩浆和断裂带相关事件的时间和相对贡献，以及它们对高品位矿脉的形成和几何形状的意义。

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.
