Area of drilling: Murmanskaya Area, southern part of the South Barents Deep, Barents Sea.Reasons for drilling: 1. Study of the geological section in the Murmansk area.2. Obtaining data for stratification of the section and its allocation with reflecting seismic horizons;3. Study of properties, composition and lithologic-facial features of sedimentary rocks.Technical results:The hole has penetrated the section of 3150 m and stopped in the Late Permian deposits.Scientific results:1. Comprehensive lithologic and paleontological studies (foraminifera, palynology) of drill samples from the hole have allowed to reveal lithologic features and to carry out a detailed lithologic and stratigraphic sequence of Late Permian, Mesozoic and Cenozoic sedimentary rocks from Permian-Triassic to Early Cretaceous. 2. Thicknesses of the units are as followed: Permian-Triassic - 88 m, Early Triassic - 212 m, Middle Triassic - 384 m, Late Triassic - 434 m, Early Jurassic - 344 m, Middle Jurassic (Aalenian-Bathonian) - 333 m, Late ...
