英文摘要	Based on the geothermal measurements in deep boreholes, this study provides the first characterization of the subsurface temperature field and the permafrost thickness in the geologically and tectonically complicated, transitional zone extending from the Yenisei-Khatanga trough to the Tunguska basin. The laboratory determinations of thermophysical properties for the main types of rocks, as well as the estimations of geothermal heat fluxes in and below the permafrost are presented. Based on the cycle of repeated geothermal measurements, the time of recovery of the temperature regime in the boreholes after drilling has been accessed. The data obtained in 2010-2013 have been used for constructing the geothermal profile up to the depth of 1.500 m characterizing peculiarities of the subsurface temperature field in the region.
