英文摘要	The formation of pore gas hydrates in frozen and thawing sand and silt sampled in permafrost areas has been studied in experiments using a special system. As demonstrated by the experimental results, gas hydrates form rapidly in gas-saturated sediments at constant negative temperatures from 0 to -8 °C. The accumulation kinetics of pore gas hydrates in permafrost has multiple controls: temperature, initial ice saturation, and salinity of soils, as well as type of hydrate-forming gas. The process can resume after its decay due to melting of residual pore ice not yet converted to hydrate. © 2019 Academic Publishing House Geo. All rights reserved.
