Abstract:
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.
