Description
Summary:Area of drilling: Murmanskaya Area, southern part of the South Barents Deep, Barents Sea.Reasons for drilling:1. Study 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 of 1600 m and stopped in Middle Jurassic (Callovian?) deposits.Scientific results:1. Within the studied geological section a detailed lithologic and stratigraphic sequence of sedimentary rocks (based on microfauna, palynology, and lithologic composition) from Middle Jurassic to Quaternary deposits has been carried out.2. Thicknesses of the units are as followed: Middle Jurassic (Callovian?) - 40 m, Late Jurassic - 342 m (Oxfordian-Kimmeridgian - 260 m, Tithonian - 82 m), Early Cretaceous - 948 m (Valanginian - 25 m, Barremian-Aptian - 71 m, Aptian - 522 m, Albian - 330 m), Late Cretaceous - 65 m, ...
