Hydrothermal fluid flow is one of the main mechanisms of mass and heat transfer in the crust, producing many of the main mineral and ore deposits. The Mount Painter Inlier in South Australia provides an excellent and well-exposed natural laboratory to study a large metasomatic-hydrothermal system. Detailed mapping and structural analysis will unravel the architecture of this system, which comprises a range of structures, from high-temperature diopside-titanite veins and pegmatites down to near-surface, low-temperature calcite veins and quartz-haematite breccias. The structural study will be supported by fluid inclusion studies, stable isotope geochemistry and geochronology, in collaboration with colleagues from the universities of Ghent (Belgium) and Leoben (Austria), to gain information on the composition and provenance of the fluids, as well as the timing and conditions (P,T) of fluid flow and tectono-metamorphic events. This project will give new insight in the temporal and spatial evolution of an exemplary metasomatic-hydrothermal system, from modes of fluid flow to structural and tectonic controls. The results will be applicable to hydrothermal systems in general.
