Area of drilling: Murmanskaya Area, southern part of the South Barents Deep, Barents Sea.Reasons for drilling: 1. Obtaining additional information on the geological section in the Murmanskaya Area as well as data for stratification of the 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 of 3445 m and stopped in 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 sedimentary rocks from Permian to Early Cretaceous ones. 2. Thicknesses of the units are as followed: Permian - 100 m, Early Triassic - 562 m, Middle Triassic - 460 m, Late Triassic - 438 m, Early Jurassic - 329 m, Middle Jurassic (Aalenian-Bathonian) 316 m, Late Jurassic - 125 m ...
