Integrated research delivers insight into Yilgarn mineralisation controls
By adding the key of time constraint to understanding evolving geological boundaries, this research helps guide future mineral exploration in the Yilgarn.
This study provides substantial new datasets for the Yilgarn, including new geophysical surveys, detailed structural analysis, geochemical and isotopic data, and ages. This data provides important new insight into how this region has evolved over time – and how it’s structural framework may have influenced the flow of ore-forming fluids during important episodes of mineralisation known to be significant to the rich endowment of the region.
While the new analysis confirms the ancient Archean crustal rocks of the region and many of the rich mineral deposits they host are well-preserved, the deeper mantle and geological structures of the region can be shown to have been substantially modified after major mineralisation, and hence do not represent strong guides to mineral exploration.
