My research includes two aspects of metamorphic fluids: the dynamics of metamorphic fluid flow and the chemical interactions between metamorphic fluids and rocks. Rocks experiencing deep metamorphism are viscously deformable and the fluid in the interconnected pores tends to be squeezed out. Different from the traditional Darcian flow which describes only the percolation of the fluid phase, this process is called compaction-driven fluid flow and can be described by the general two-phase flow theory. Numerical studies of the coupling between rock compaction and metamorphic devolatilization suggest a new form of fluid flow called porosity waves. Along with porosity waves are fluid pressure oscillations and fluid flux pulses which are not predicted by the traditional flow model. My current research is to reevaluate this compaction-driven flow in comparison with the traditional Darcian flow in terms of fluid driven reaction progress, energy and mass transport. Specifically, I am applying this compaction-driven fluid flow model to the deep carbon transport process to constrain deep metamorphic carbon fluxes.
