Abstract:
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.
