Coupled, one-dimensional transport equations for CO2 and O2 in pre-Middle Ordovician soils have been developed. The value of the ratio ΔPO2 /ΔPCO2 , where ΔPO2 is the difference between the O2 pressure in the atmosphere and at any level in a particular soil profile, and where ΔPCO2 is the difference between the CO2 pressure in the atmosphere and at the same level in the same soil profile, depends on the relative importance of O2 and CO2 transport by diffusion and transport by advection in soils.
