- Abstract:
- Alteration systems and chemical fluxes associated with the alteration and weathering of seamounts have never been fully characterised or quantified. During this project we will focus on two seamounts from the Emperor seamount chain, drilled during ODP Leg 197 and erupted in both submarine and subaerial environments. The aims are to (a) Characterise seamount alteration systems; (b) Quantify the chemical exchanges and (c) Determine if these interactions can significantly influence ocean chemistry. Through a comprehensive programme of petrography and chemical and isotopic analyses of fresh and altered lavas and secondary minerals, we will establish the paragenetic sequences of alteration as well as the nature of the fluids involved. These analyses will determine the physical and chemical conditions of fluid-rock exchange and quantify chemical fluxes associated with these reactions.
