Molybdenum (Mo) is a high technology metal, which is of economic importance due to its wide range of applications, ranging from high performance lubrication, catalysis, to super alloys, heating elements, or similar technological equipment. Whilst it is well known that Mo-bearing ore deposits are formed by hydrous fluids deep inside the Earth’s crust, little is know about the structure and the chemical composition of the ore forming fluids. Hence we will systematically study the solubility of Mo-minerals in hydrothermal fluids at high pressures and high temperatures using a new hydrothermal apparatus and synchrotron radiation. Furthermore, we will also investigate the stability of various Mo complexes in hydrothermal fluids at a range of pressures, temperatures and in fluids of different chemical composition.

钼（Mo）是一种高科技金属，由于其广泛的应用范围而具有经济重要性，从高性能润滑，催化到超级合金，加热元件或类似的技术设备。虽然众所周知，含钼矿床是由地壳深处的含水流体形成的，但对成矿流体的结构和化学成分知之甚少。因此，我们将利用新型热液装置和同步辐射技术，系统研究钼矿物在高温高压热液中的溶解度。此外，我们还将研究各种钼络合物在热液流体中在一系列压力，温度和不同化学组成的流体中的稳定性。
