Abstract
The material in the article contains biographical information from the life and scientific activity of the doctor of geological and mineralogical sciences, professor, academician Academy of Sciences of the USSR A.D. Arkhangelsky. A wide range of the scientist is shown and a description of the main directions of research in the field of regional geology, fauna and stratigraphy of the Paleogene and Upper Cretaceous deposits of the Volga and Central Asia, lithology and paleography, issues of tectonics and the relationship of gravitational and magnetic anomalies with the geological structure of the territory of the USSR is given. The main attention is paid to his work in the study of the geology of oceans and seas. The main contribution of the scientist to the study of Mesozoic bauxites, their structure and mineral composition is described. On this basis, the scientist developed and substantiated a new sedimentary theory of their formation. This theory opened the possibility for geologists to approach the study of bauxite as sedimentary rocks; this played an important role in the search for new deposits of this valuable mineral. The complex of geological and geophysical work carried out by him on expeditions along the East European Plain provided an answer to important questions about the distribution of oil, coal and iron ores on the territory of the Russian Platform. Much attention was paid to the study of the geology of the Black Sea. Processing materials collected by a hydrographic expedition and a comparative study of the columns of the Black Sea silt and oil-bearing sediments of the Crimean-Caucasian region led the scientist to important conclusions about the conditions of accumulation of oil-producing suites. Long-year research A.D. Arkhangelsk sediments of the Black Sea, their lithology, geochemistry, structure, subsequent changes and deformations were summarized in a number of works, among which are “Conditions for the formation of oil in the North Caucasus” (1927), “Geological history of the Black Sea” (1932), “Geological structure and the history of the development of the Black Sea“ (1938), written together with N.M. Strakhov. In 1926—1928 Arkhangelsky lead the field geological survey work on the Kerch Peninsula for the study of oil fields.
