摘要：

Results of the investigation into the geothermal regime of the Fore-Yenisey sedimentary basin, formed during the collision and subsidence of the Kas-Turukhan microcontinent and the western margin of the Siberian craton in the late Neoproterozoic and early Paleozoic are reported. It was established that the structural and geothermal conditions of the upper Precambrian-Paleozoic sections are similar to those in the western regions of the Siberian platform and are characterized by rather low geothermal gradients (12.5-25.5 degrees C/km). In the western parts of the basin, formation temperatures in the uppermost pre-Jurassic sediments are 50 degrees C-85 degrees C, decreasing eastward to 30 degrees C-55 degrees C. For the first time, the detailed geothermal model of the basin sedimentary fill was developed. This model allows predictions of the geothermal conditions of Earth's interior.
