Precipitation in Pores: A Geochemical Frontier
November 23, 2015
- The effects of porous media on precipitation reactions are shown to be important, but poorly understood.
Significance and Impact
- Geochemical reactions within rocks and soils occur in pores. Yet, there is not agreement on how the pores affect the reactions, which limits the ability ro predict reactions in the subsurface.
- The different theories for how precipitation in pores occurs and are reviewed and their significance for macroscopic properties wuch as fluid transport, porosity, and permeability, are evaluated
- It is demonstrated how X-ray/neutron scattering, combined with computational simulation may allow us to resolve this discrepancy observing geochemical reactions directly within a rock
