Research article (journal) | Peer reviewedWe present a new autoclave, which enables in-situ characterization of hydrothermal fluids at high pressures and high temperatures at synchrotron X-ray radiation sources. The autoclave has been specifically designed to enable X-ray absorption spectroscopy in fluids with applications to mineral solubility and element speciation analysis in hydrothermal fluids in complex compositions. However, other applications such as Raman spectroscopy in high-pressure fluids are also possible with the autoclave. First experiments were run at pressures between 100 and 600 bars, and at temperatures between 25°C and 550°C, and preliminary results on scheelite dissolution in fluids of different compositions show that the autoclave is well suited to study the behavior of ore-forming metals at P-T conditions relevant to the Earth's crust.
