| Summary: | The hole was drilled in the Severo-Kildinskaya Area in the southern part of the Barents Sea within the South Barents tectonic depression.Reasons for drilling:1. Specification of the geological structure of the area and obtaining data for stratification of the geological section and its allocation with reflecting seismic horizons.2. Study of properties, composition and lithologic-facial features of sedimentary rocks.Technical results:The hole has penetrated the section up to 1883 m and stopped in Early Triassic deposits.Scientific results:1. Within the studied geological section a lithologic and stratigraphic sequence of sedimentary rocks (based on microfauna, spora and pollen spectra, bivalve mollusks, and lithologic composition) from Early Triassic to Quaternary deposits has been carried out.2. Thicknesses of the units are as followed: Early Triassic - 310 m (Induan - 13 m, Olenekian - 297 m), Middle Triassic - 198 m, Late Triassic - 271 m, Early Jurassic - 152 m, Middle Jurassic - 178 m, Late Jurassic - 96 ... |
