Project outline

This project will focus on the adsorption and co-precipitation of a variety of biogeochemically active elements to Green Rust (GR), and will investigate the subsequent potential for these elements to be either fixed in the sediment or released to solution during early diagenesis. A dual approach will be taken, involving detailed laboratory experiments, followed by ground-truthing of the experimental results in a modern ferruginous basin (Lake La Cruz, Spain). Particular focus will be on the differing behaviour of individual elements during oxic and anoxic GR formation and transformation pathways. The ultimate goal will be to build an understanding of the role of GR in the biogeochemical cycling of elements such as P, Ni (essential for methanogenesis), and Cu (essential for aerobic methanotrophy) under ferruginous conditions.

This, in turn, will provide greater understanding of the potential for these elements to limit key biogeochemical processes in the ancient and future ocean. The main hypothesis to be tested is whether the multitude of experimental data that currently exists with regard to elemental adsorption to Fe oxides is really appropriate in terms of processes operating under anoxic, ferruginous water column conditions.
