| contents | Project: 74-2/894 - Proceeding and Generalization of Materials of Parametric Drilling on Arctic Islands (the Bely-1 parametric drill hole, Kara Sea). Area of drilling: The Bely (White) Island, the periclinal part of the Bely Island structure, 14 km from the western coast of the island. Reasons for drilling: 1. Comprehensive study of the geological section, identifying the main regularities and features of the geological structure in the area. 2. Specification of data on stratigraphic sequencing (rock age, lithology, paleontology, thickness of stratigraphic units), creating a regional geological-geophysical section. Technical results: The hole was drilled from 29.09.1983 till 17.09.1984. It has penetrated the section of 3500 m and stopped in Early Cretaceous deposits. Scientific results: 1. Within the studied geological section a detailed lithologic and stratigraphic sequence of sedimentary rocks (based on different fauna groups and lithologic composition) from Early Cretaceous to Quaternary deposits has been carried out. 2. Thicknesses of the units are as followed: Early-Late Cretaceous - 3140 m (Berriasian - Early Hauterivian - 211 m, Hauterivian - Aptian - 1009 m, Aptian - Cenomanian - 880 m, Turonian - Maastrichtian - 1040 m ), Paleogene - 129 m, Quaternary - 231 m. 3. Typical matter complexes and physical properties of the rocks have been determined for interpreting geophysical data and referencing geophysical sections. 4. The stratigraphic units, rock types, and the matter complexes in the section are similar to ones in the adjacent areas that has resulted to reliable correlation and identifying the main regularities of sedimentation. 5. The Mesozoic-Paleogene terrigenous rock complex reflects the humid type of sedimentation. 6. The Cretaceous series in the Bely Island is similar to one in the Yamal Peninsula. It is an alternation of silty-sandy and silty-clayey layers. 7. In general the section in the hole is typical not only for the Yamal Peninsula but also for the northern part of the West Siberia. |
