In the primitive Earth, a wide range of phenomena including the initiation of biological activity and the formation of ore deposits were related to the mobilisation of mineralised fluids through the crust. In the Archaean craton of the Pilbara (WA), we have identified, within its tectonic framework, a crustal-scale plumbing system that channelled large volumes of mineralised hydrothermal solutions. Our objective is to understand the development of this plumbing system in relation to Archaean crustal geodynamics using a combination of structural geology, metamorphic petrology, geochronology, geochemistry, and the analysis of single-fluid inclusion using synchrotron and other X-ray sources.

在原始地球，包括生物活动的启动和矿床的形成在内的各种现象都与矿化流体通过地壳的活动有关。在皮尔巴拉（WA）的克拉通，我们已经确定，在其构造框架内，一个地壳规模的管道系统，引导大量的矿化热液溶液。我们的目标是了解这个管道系统的发展与地壳地球动力学的结合使用构造地质学，变质岩石学，地质年代学，地球化学，并使用同步加速器和其他X射线源的单流体包裹体的分析。
