Project description
My project is focused on identifying, investigating, and quantifying feedback mechanisms in fluid-rock interactions. Silicate-silicate feedback mechanisms are explored by a systematic experimental approach using the serpentinization of olivine and pyroxene as a model system. Further, a silicate-sulfide system will be explored, investigating feedback mechanisms in tenor upgrading of sulfide ore deposits. The feedback mechanisms are quantified via kinetic modelling by extracting kinetic parameters from experimental results. Finally, experimental results will be linked to natural observations to constrain alteration reaction sequences and timescales.
