Redox microniches in groundwater: a model study on the geometric and kinetic conditions required for concomitant Fe oxide reduction, sulfate reduction, and methanogenesis

A pore‐scale model using PHAST is used to study the distribution of redox processes and other geochemical processes in intergranular and intragranular microniches in a groundwater system. The goal is to determine the geometric and kinetic conditions that may give rise to the presence of methane unde...
