| Summary: | Area of work: The Kolguev Island (Barents Sea) in the area of the positive Peschanoozerskaya Structure detected during seismic survey.Reasons for drilling:1. Comprehensive study of the geological-geophysical section of the shelf in the area of the Kolguev Island. Study of stratal waters.2. Identification of the main regularities and features of the geological structure in the drill section.3. According to the program of drilling on islands and coasts of Arctic seas for creating a network of geological reference points for reliable referencing of geophysical data.Technical results:The hole was drilled in 1986-1987. It has penetrated the section up to 3005 m and stopped in Early Permian siliceous limestones.Scientific results:1. A lithologic and stratigraphic sequence of sedimentary rocks (based on brachiopods, foraminifera, and palynology) from Early Permian to Neogene-Quaternary deposits has been carried out in the studied geological section. Composition of rocks (mineralogy, clay mineralogy, chemical ... |
