Abstract:
Project: Exploration drilling of the hole Raddedalen-1 (Edge Island, Spitzbergen Archipelago).
Area of drilling: Edge Island, Svalbard Archipelago, area of the outcrop of Permian silicified limestone on the western shore of the river Kroks.
Reasons for drilling:
1. Study of geological-geophysical section of the hole.
2. Obtaining information for regional geological reconstructions and for interpretation marine geophysical materials.
3. Comprehensive study of properties, composition and lithologic-facial features of sedimentary rocks from the geological section.
Technical results:
The hole was drilled from 02.04.1971 till 10.07.1971. It has penetrated the section of 2823 m and stopped in Ordovician - Early Silurian deposits.
Scientific results:
1. Comprehensive lithologic and paleontological studies of drill samples from the hole have allowed to reveal lithologic features and to carry out detailed lithologic and stratigraphic sequence from Early Silurian - Ordovician to Late Permian sedimentary rocks.
2. The hole has crossed the section contained 1949 m of Ordovician - Early Silurian deposits, 468 m of Carboniferous deposits, and 406 m of Permian deposits.
3. The Ordovician and Early Silurian - Ordovician deposits occur in the interval from 874 to 2823 m. They comprise limestones with rare argillite bands and a coal band about 1 m thick at the horizon 1049 m. The Ordovician deposits occur in the interval 1819-2823 m, the Early Silurian - Ordovician deposits occur in the interval 874-1819 m. Presumably the boundary between the Ordovician and Silurian is at the horizon 1649 m.
4. The Carboniferous deposits occur in the interval from 407 to 874 m. The Early Carboniferous deposits occur in the interval 713-874 m, the Middle-Late Carboniferous deposits - in the interval 407-713 m. The Early Carboniferous deposits comprise sandstones; in the lower part of the interval there occur 4 coal bands up to 1.4 m thick. The Middle-Late Carboniferous deposits comprise limestones with bands of quartzitic sandstones in the base.
5. The Permian deposits occur in the interval from 0 to 407 m. The Early Permian deposits occur in the interval 202-407 m, the Late Permian deposits - in the interval 0-202 m. The Early Permian deposits comprise limestones with bands of sandstones, dolomite, and anhydrite. The Late Permian deposits comprise intercalation of limestones (often siliceous ones), quartzitic sandstones, and argillites.
5. The mentioned deposits lay almost horizontally.
6. The Early Carboniferous deposits overlay the Early Silurian - Ordovician ones with stratigraphic disconformity.
7. Density of rocks varies from 2.4 to 2.9 g/ccm.
8. The Early Carboniferous series can be used as a seismic benchmark.
