Results of the investigation into the geothermal regime of the Fore-Yenisei 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 ° km−1). In the western parts of the basin, formation temperatures in the uppermost Pre-Jurassic sediments are 50–85 °, decreasing eastward to 30–55 °. For the first time, the detailed geothermal model of the basin sedimentary fill was developed. This model allows predicting the geothermal conditions of the earth's interior.

前叶尼塞沉积盆地地热模型——古西伯利亚地台与年轻西西伯利亚板块之间的过渡构造

报道了晚新元古代和早古生代Kas-Turukhan微大陆和西伯利亚克拉通西缘碰撞沉降形成的Fore-Yenisei沉积盆地地热状况的调查结果。确定上前寒武统—古生界的构造和地热条件与西伯利亚台地西部地区相似,地温梯度较低(12.5-25.5°km -1)。在盆地西部,最上部的前侏罗纪沉积物地层温度为50-85°,向东降低至30-55°。首次开发了盆地沉积填充物的详细地热模型。该模型允许预测地球内部的地热条件。
