Fluid mixing in hydrothermal systems

Fluid mixing in hydrothermal systems. Mixing of fluids within permeable rocks can cause significant chemical changes to the fluids and the rocks, for example it causes metals to be dissolved and transported. Accumulation into mineral deposits requires concentration mechanisms which are uncertain due to difficulty of detecting ancient fluid pathways. We will analyse these ancient fluids using new microanalytical and other combined techniques, thereby testing the role of fluid mixing as a mechanism for efficient metal precipitation. The research has significance for exploration and models for mineral deposits, and for characterising other geological fluids, and provides opportunity for technical breakthroughs in microanalysis of fluid inclusions.
