- Аннотация: Application of the Basin Modeling package GALO together with its specific modification (the FROST program package) allowed us to carry out the numerical reconstruction of temperature and heat flow distributions with depth during basin subsidence and the assessment of permafrost evolution during the Pliocene-Quaternary. Computations have been accomplished for two sedimentary sections: the Urengoy field in the West Siberian Basin and the Kuyumbinskaya field in the Kamov swell on the East Siberian Platform. Calculations of the thermal regime of the sedimentary stratum evidence a significant role of rock lithology in permafrost evolution. Numerical assessments point to a decrease in rock temperatures by 15-20 °C within the upper 1500 m of sedimentary section due to the climate cooling in the Pliocene-Holocene. In spite of warmer climate, the cooling effect in the Kuyumbinskaya area occurs to be deeper and more intensive due to the relatively thin sedimentary cover in comparison with that one in the more northern Urengoy area.
