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 Jurassic - 112 m (Callovian-Kimmeridgian - 91 m, Tithonian - 21 m), Early Cretaceous - 1243 m (Berriasian-Hauterivian - 43 m, Barremian-Aptian - 491 m, Albian - 709 m). The question about presence or absence of Late Cretaceous and Paleogene deposits (mapped in the South Barents Deep) in the section remains undetermined. Presumably these deposits have low thickness and occur above the sampling interval.3. Sedimentation rate varied from 0.3 cm/kyr in the Late Jurassic to 10 cm/kyr in the Early Triassic.4. Pre-Valanginian washout and weathering crust as well as pre-Cenozoic washout have been identified. Hiatuses are assumed in the post-Jurassic, post-Valanginian, and pre-Cenozoic time.5. Generally clayey-silty sedimentary rocks dominate in the hole. Silty-sandy rocks dominate in the Permian, Triassic, Early and Middle Jurassic.6. Coals of gas stage metamorphism occur in the Permian, Late Triassic, Middle Jurassic and Late Aptian deposits.7. Sedimentation environment has been reconstructed. Permian to Triassic sediments accumulated in Lagoonal-continental and lagoonal-marine conditions. Triassic to Jurassic sediments accumulated in lagoonal-continental and continental conditions. Middle Jurassic to Early Cretaceous sediments accumulated in a marine mainly shallow basin, which deepened in the Late Jurassic.8. Maximal downwarping was in the Permian, Triassic and in the end of the Early Cretaceous.9. Sedimentary rocks are lithified from ones affected by deep epigenesis (Permian to Triassic) to ones affected by early epigenesis (Early Jurassic to Early Cretaceous).10. Mineral composition of sedimentary rocks from the Murmansk area strongly differs from one of deposits in the Kolguev Island and the Timan-Pechora region.11. During the Late Jurassic black clays enriched in organic matter accumulated. This resulted from scarcity of sedimentary material, very low sedimentation rates, and a rather deep basin of sedimentation.
