Probabilistic nucleation governs time, amount, and location of mineral precipitation and geometry evolution in the porous medium

Abstract One important unresolved question in reactive transport is how pore-scale processes can be upscaled and how predictions can be made on the mutual effect of chemical processes and fluid flow in the porous medium. It is paramount to predict the location of mineral precipitation besides their...
