    Description: Project 74-4/683 - Proceeding and Generalization of Materials of Parametric Drilling on Arctic Islands (Nagurskaya and Severnaya parametric drill holes on the Franz Josef Land Archipelago). Reasons for drilling: 1. Study of the geological-geophysical section from the first deep drill hole on the Franz Josef Land Archipelago for providing reliable referencing of geophysical materials, for establishing structure of the sedimentary cover, rock properties and composition. 2. Obtaining information for stratification of the section and its allocation with geophysical sections. Technical results: The hole has penetrated the section of 3204 m and stopped in Neoproterozoic (Ediacaran) deposits. Scientific results: 1. The hole has crossed terrigenous and carbonaceous sedimentary rocks, metamorphic formations, and magmatic intrusive and effusive rocks. Besides, the hole has crossed a series of steeply dipping high amplitude disjunctive dislocations. 2. Stratigraphic sequence (based on different faunal groups, leaf flora, sporen, pollen) of the section has been carried out. 3. Two rock complexes have been defined in the section. From surface up to 1895 m there occurs a platform mantle composed of Triassic and Carboniferous carbonaceous-terrigenous rocks and Cretaceous terrigenous-volcanogenic rocks. This platform mantle is underlain by a folded basement 〉1309 m thick composed of Neoproterozoic shales and quartzites. 4. The platform mantle rocks lay almost horizontally in the followed sequence (from down to up): Early Carboniferous sandy-silt deposits of a paralic coal-bearing formation (155 m), Upper Carboniferous biogenic limestones (83 m), Early and Middle Triassic shallow marine silty-clayey deposits (1375 m), Early Cretaceous sedimentary-volcanogenic formation composed of blanket basalts with layers of clays and coaly argillites (283 m). 5. Neoproterozoic (Ediacaran) basement rocks dip at angles of 20-750. Quartz-sericitic microschists predominate in the lower part, microquartzites - in the upper part. These rocks belong to the greenschist facies of regional metamorphism. 6. The hole has crossed 21 intrusive bodies from 4 to 160 m thick along the borehole. Both steeply dipping dikes and layered bodies occur, mostly in the basement rocks. The followed rock types of the trapp formation occur: microdolerites (dolerites), gabbro-dolerites, quartz gabbro-dolerites, and taxitic gabbro-dolerites. Magma intruded in two phases: Late Triassic - Early Jurassic (between 205 and 190 myr BP) and Early Cretaceous (between 130 and 100 myr BP). 7. Accumulation of homogeneous Early Triassic silty-clayey deposits was in different conditions. Lower horizons (interval 1500-1600 m) accumulated in a marine basin with normal salinity in a quiet tectonic environment and slow compensate accumulation of clay sediments in reduced conditions. Upper horizons (500-1500 m) accumulated with high sedimentation rates in a marine basin with disturbed salinity in reduced conditions.

    Description: Project 74-4/683 - Proceeding and Generalization of Materials of Parametric Drilling on Arctic Islands (Nagurskaya and Severnaya parametric drill holes on the Franz Josef Land Archipelago). Reasons for drilling: 1. Study of the geological-geophysical section from the eastern part of the Franz Josef Land Archipelago for establishing structure of the sedimentary cover, rock properties and composition. 2. Obtaining information for stratification of the section and its allocation with geophysical sections. Technical results: The hole was drilled from 14.12.1977 till 03.01.1979. It has penetrated the section of 3523 m and stopped in Early?-Middle Triassic deposits. Scientific results: 1. Stratigraphic sequence (based on different faunal groups, leaf flora, sporen, pollen) of the section has been carried out. 2. Middle-Late Triassic deposits lay almost horizontally. Middle Triassic deposits are composed of dark-colored terrigenous rocks of marine origin. They are divided to two series. The lower series 1025 m thick is composed of alternating patterns of sandstones, siltstones, and argillites with predomination of silty-clayey rocks. The upper series 430 m thick is composed of argillites with small admixture of silty material. 3. Upper Triassic deposits are composed of (from down to up): marine sandy-silty Carnian rocks (470 m), a series of rhythmically alternating obliquely laminated sandstones and siltstones with tributary layers of argillites, coaly rocks, hard coal lenses (990 m), dark marine silty clays (160 m), a series of obliquely laminated sands and sandstones with pyrite and siderite concretions (450 m). 4. The hole has crossed 6 sills from 5 to 87 m thick. The sills occur with interval 400-600 m and comprise ~6% of thickness of the sedimentary complex. Thinner sills (5-7 m) are composed of glassy dolerites and microdolerites, the thickest sills are composed of micropegmatite gabbro and olivine gabbro-dolerites. The sills intruded from the end of the Early Cretaceous till the Early Paleocene. 5. During the Middle Triassic and Carnian sedimentation was within a marine basin with highly reduced conditions. During most of the Norian sediment formation was within a vast littoral lake-alluvial plain that periodically submerged and flooded by sea.

    Description: Project 74-5/719 Generalization of results from parametric and exclusive prospecting drill holes on the shelf of the Barents and Kara Seas. Reasons for drilling: 1. Comprehensive study of properties, composition and lithologic-facial features of sedimentary rocks from the geological section in the West Svalbard. 2. Obtaining information for stratification of the section and its allocation with geophysical sections. Technical results: The hole was drilled from 24.07.1979 till 01.01.1980. It has penetrated the section of 2236 m and stopped in Proterozoic metamorphic rocks. Scientific results: 1. Comprehensive lithologic and paleontological (different fauna groups, leaf flora, sporen, polen) studies of drill samples from the hole have allowed to reveal lithologic features and to carry out lithologic and stratigraphic sequence of sedimentary rocks. 2. Thicknesses of the units are as followed: Proterozoic - 715 m, Jurassic - 166 m, Cretaceous - 1372 m, Quaternary - 82 m. The Mesozoic deposits are composed of ones from the followed formations: Late Jurassic 166 m thick, Nizhnekhetskaya (Early Cretaceous) 134 m thick, Sukhodudinskaya (Early Cretaceous) 50 m thick, Malokhetskaya (Early Cretaceous) 210 m thick, Yakovlevskaya (Early Cretaceous) 480 m thick, Dolganskaya (Cenomanian) 216 m thick, and Turonian-Santonian 282 m. 3. Two structure complexes exist in the section of the hole: the platform cover 1620 m thick, and the folded base 〉715 m thick. In the platform cover Quaternary-Jurassic rocks lay almost horizontally; these are low-lithified marine and lagoonal-marine coal-bearing ones. The base Proterozoic rocks dip at angles 50-700. 4. In the platform cover low lithified sandy and silty-sandy deposits prevail (~60%). The base consists of metamorphosed biotite-amphibole-quartz schists, quartz-micaceous and micaceous-carbonate microschists, microquartzites. 5. Physical properties of sedimentary rocks are controlled by grain size composition, carbonate content and degree of catagenesis. 6. Genetic similarity of the Mesozoic deposits from the area of the Sverdrup Island with coeval deposits from the north-eastern part of the West Siberia and from the Enisey-Khatanga trough has been found. Proterozoic metamorphic rocks are similar to Early Proterozoic deposits from the western part of the Taymyr Peninsula. 7. In the Late Jurassic and Cretaceous sedimentation process developed in low-reduced conditions in a marine basin and within a vast littoral lake-alluvial plain that periodically submerged and flooded by sea. Sometimes marine conditions predominated.

    Description: Project 74-4/625 Proceeding and Generalization of Materials of Parametric Drilling on Arctic Islands (Grumant parametric drill hole on the Western Spitzbergen). Reasons for drilling: 1. Comprehensive study of properties, composition and lithologic-facial features of sedimentary rocks from the geological section in the West Svalbard. 2. Obtaining information for stratification of the section and its allocation with geophysical sections. Technical results: The hole has penetrated the section of 3173 m and stopped in Permian deposits. 620 samples have been collected. Scientific results: 1. Comprehensive lithologic and paleontological (different fauna groups) studies of drill samples from the hole have allowed to reveal lithologic features and to carry out detailed lithologic and stratigraphic sequence of Permian, Mesozoic and Paleogene sedimentary rocks. 2. Typical matter complexes have been determined and their geophysical characteristics have been given. 3. Two rock complexes have been revealed in the section. The Permian complex is composed of siliceous-carbonate rocks with anhydrite layers and corresponds to arid lithogenesis. The Mesozoic-Paleogene terrigenous rock complex corresponds to humid sedimentation. 4. The Permian deposits strongly differ from the Mesozoic-Paleogene terrigenous rocks on trace element contents and their paragenetic relations. 5. In general, stratigraphic units, rock types, and matter complexes in the hole are similar to ones in adjacent areas. This is a good base for reliable correlation and identifying the main regularities of sedimentation from the Permian to the Paleogene. 6. The Permian deposits strongly differ in chemical composition from younger ones. Terrigenous rocks corresponding to regressive phases of sedimentation strongly differ from ones corresponding to transgressive phases. 7. Thickness of the Upper Permian deposits varies in a wide range and depends on intensity of the pre-Triassic washout. Thickness of the Triassic deposits decreases eastward. 8. Thickness of the Jurassic and Early Cretaceous deposits in the near-axial part of the Western Svalbard sag is 410-450 m higher than in the flange parts. 9. The Western Svalbard sag as a sedimentation basin began to form in the Tithonian and formed during the whole Early Cretaceous. In the Paleogene a tendency to steady downwarping of its axial part continued.
