- Abstract:
- Key parts of the global sulphur cycle remain poorly understood; in particular, the controls on the formation and stability of greigite (important palaeomagnetic diagnostic phase) during sediment diagenesis and burial are unknown. This project will characterise a range of modern diagenetic environments to constrain the natural variability in concentrations of the redox-sensitive S and Fe species. Experiments performed under conditions comparable to the natural equivalents will ascertain the key chemical factors controlling the growth and stability of greigite and real-time and in situ synchrotron-based spectroscopic and chemical studies will ascertain kinetic rates and mechanisms for the reactions between the different Fe-S phases.
