Processing results from drill hole VNIIO-1987-Ich-Tarsk on the Kolguev Island (Leningrad)
Area of work: The Kolguev Island (Barents Sea) in the area of the positive Peschanoozerskaya Structure detected during seismic survey. Reasons for drilling: 1. Comprehensive study of the geological-geophysical section of the shelf in the area of the Kolguev Island. Study of stratal waters. 2. Identi...

In the interval from 2800 to 2440 m it is overlain by a limestone series with interlayers of marls, sandstones, and argillites; this series accumulated from the Early to Late Permian. The upper stage (2440-0 m) is mainly composed of terrigenous rocks. In the interval from 2440 to 855 m there occurs a chiefly terrigenous series accumulated from the Late Permian to Triassic.
