英文摘要	The characteristics of the geothermal conditions in the Vilyui basin have been adduced. The Vilyui basin is located within the Siberian Platform and contains disequilibrium permafrost. Recently obtained data on permafrost thickness and temperature distribution for geological units of the Vilyui basin have been presented. Estimates of geothermal heat fluxes in and below the permafrost are given. It has been determined that the heat flux in the permafrost is 30-34 mW/m2 lower than in the subpermafrost zone. Four intervals are identified on the temperature curves differing in geothermal gradient and indicating different paleoclimatic conditions in the course of permafrost development. Based on the obtained data, a 2.000 m depth geothermal profile characterizing the geothermal field in the region has been plotted.
