Experiments on gas passage through metamorphic rocks

Results of the experiments on passing air and gas CO2 through samples of me tamorphic rocks at atmospheric pressure and room temperature are plotted. I t has been established that the flow of CO2, in contrast to other gases, is governed by sorption-desorption processes, which have pulse behavior in th e presence of water vapor, rather than by pressure difference. Generation a nd development of gas sorption-desorption on dried samples are considered. The flow of CO2 has both continuous and discrete components. The discrete c omponent has pseudoharmonic behavior and causes spasmodic changes of the co ntinuous one. The data obtained agree with known laws of fluid flow on filtration of the system gas-water through natural porous media.
