Fluid-Wegsamkeiten in großräumigen metasomatisch-hydrothermalen Systemen: eine Fallstudie des Mount Painter Inliers, Südaustralien

热液流动是地壳中质量和热量传递的主要机制之一，产生了许多主要的矿物和矿床。南澳大利亚的Painter Inlier山为研究大型交代热液系统提供了一个极好的、暴露良好的自然实验室。详细的制图和结构分析将揭示该系统的结构，该系统包括一系列结构，从高温透辉钛矿脉和伟晶岩到近地表，低温方解石脉和石英-赤铁矿角砾岩。构造研究将得到流体包裹体研究、稳定同位素地球化学和地质年代学的支持，与根特大学（比利时）和莱奥本大学（奥地利）的同事合作，以获得有关流体组成和来源以及流体流动和构造变质事件的时间和条件（P，T）的信息。该项目将从流体流动模式到构造和构造控制，为典型的交代-热液系统的时空演化提供新的见解。结果将适用于一般的热液系统。

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.
