Project title: Natural analogues for CCS: using travertine deposits as records of leakage and fluid-rock interaction at Green River (Utah)
Supervisors: Mike Bickle (Cambridge), Dan Condon (BGS) & Niko Kampman
Natural analogues are the only method which we can use to understand the long-term (100 to 10,000 year) storage security of CO2. We use a field area at Green River (Utah) where there has been periodic leakage of CO2 rich brines up two fault systems. This project aims to utilise travertine deposits as records of leakage, and to use the chemistry of these deposits to reconstruct rates of fluid-mineral reaction under conditions close to equilibrium.
