Reasons for drilling:1. Study of geological structure of the north-western Barents Sea shelf according to the programs of study of Arctic geology and creating geological reference points for reliable referencing of geophysical data.2. Detailed correlation with regional geological-geophysical sections of Late Paleozoic, Mesozoic and Paleogene deposits.Technical results:The hole has penetrated the section of 2352 m and stopped in Middle Triassic deposits. The hole was drilled 40 m to the south of the hole Vassdalensk-2.Scientific results:1. Comprehensive lithologic and paleontological studies (based on different fauna groups) of drill samples from the hole have allowed to reveal lithologic features and to carry out a detailed lithologic and stratigraphic sequence of Mesozoic and Paleogene sedimentary rocks.2. Thicknesses of the units are as followed: Middle-Late Triassic - 302 m, Jurassic - 174 m, joint Late Jurassic - Early Cretaceous - 89 m, Early Cretaceous - 979 m, Paleogene - 776 m, Quaternary - 32 m.3. ...
