Abstract

In order to clear up a possibility of melt degassing through pores and microcracksd density, porosity and permeability were studied on the samples of main types of rocks, forming the Elbrus volcanic center. The results of the study were applied to estimation of filtration rate for individual gases: He, Ar, Cl2, F2, H2S, CO2, H2, O2, H2O. It was found that the filtration rates of about 10-5 cm/s within the concerned section prevail.
