The Genesis and Tectonic Setting of Iron Oxide Associated Mineralisation in Germany and South Australia. FeOx associated mineralisations are not restricted to Olympic Dam and Ernest Henry types but occur in various geological settings, e.g. the Mt Painter and Olary region, S A. Ocurrences in Central Europe (Erzgebirge, Harz/Calvörde) contain U and other metals, their structural setting is well recorded. Together with the Bergakademie Freiberg, Germany, and the University of Nancy, France, these ....The Genesis and Tectonic Setting of Iron Oxide Associated Mineralisation in Germany and South Australia. FeOx associated mineralisations are not restricted to Olympic Dam and Ernest Henry types but occur in various geological settings, e.g. the Mt Painter and Olary region, S A. Ocurrences in Central Europe (Erzgebirge, Harz/Calvörde) contain U and other metals, their structural setting is well recorded. Together with the Bergakademie Freiberg, Germany, and the University of Nancy, France, these mineralisations shall be investigated with modern geological and geochemical methods to develop a unifying model for the genesis of iron oxide associated U-metal-REE deposits. This will help identifying exploration targets and distinguish different types of mineralisation upon their genetic setting.Read moreRead less
Three-dimensional flow, temperature and melting distributions in mantle subduction zones. We will predict spatial distributions and time evolution of temperature and magma production in subduction zones, where cold oceanic plates sink into the Earth's mantle, recycle crust and sediments, and generate volcanic arcs. Three-dimensional laboratory experiments, including 3-D flow visualization and high-resolution temperature measurements, will model slab segments, different rates and modes of subduct ....Three-dimensional flow, temperature and melting distributions in mantle subduction zones. We will predict spatial distributions and time evolution of temperature and magma production in subduction zones, where cold oceanic plates sink into the Earth's mantle, recycle crust and sediments, and generate volcanic arcs. Three-dimensional laboratory experiments, including 3-D flow visualization and high-resolution temperature measurements, will model slab segments, different rates and modes of subduction and upward transport of melt. Ocean trench migration (?rollback? subduction) is of special interest because it gives patterns of temperature and vertical motion most conducive to melting. Results will be used to interpret geochemical and seismic data from the Tonga subduction zone in the South Pacific.Read moreRead less
