Gan Duan

Postdoctoral Fellow in Geochemistry

I am a geochemist working on fluid/gas rock reactions under different conditions. My research interests include the fluid-rock interactions of diagenesis, hydrothermal ore-forming processes and crustal metasomatism, pressure effect on the re-equilibrium of carbonate mineral fluid systems, thermodynamic modelling of fluid-rock reactions. During my research journey, I have worked on several commercial and scientific projects involving the characterization of alteration minerals as an indicator of deep buried ore deposits, exploring the potential effects of pore fluid pressure on mechanisms for leaching and remobilizing of elements of carbonate minerals, and investigating the effect of halides in the feldspar albitization process.

Currently, with the Deep Earth Imaging Future Science Platform, I am working on the underground storage of hydrogen and understanding the mechanisms that drive natural hydrogen genesis.
