Jena is exploring the formation mechanisms of mixed-valence iron silicate minerals under anoxic and microaerophilic conditions in natural and laboratory-based ferruginous, silica-rich systems. Jena’s projects involve using a spectrum of analytical and spectroscopic techniques to characterize iron silicates found in chert nodules in ancient iron formations as well as in modern settings in volcanic crater lakes.
