Abstract

This work reports on the laboratory study of gas filtration in ice samples with various salinities and frozen soils. For this purpose, the frozen soils were affected by pressurized gas in a specially designed apparatus. Then, the structure of the samples was studied with the use of the texture and structure observations in transmitted, reflected, and polarized light. During the experiments, it was possible to identify the processes that accompany gas filtration in ice with various salinities and frozen soils, and to establish the temperatures at which gas filtration begins.
