ЭКСПЕДИЦИЯ ГЕОЛКОМА ВСНХ СССР (1925 Г.) ПО ОЦЕНКЕ ЗОЛОТОНОСНОСТИ БАССЕЙНА Р. АЛДАН

Abstract

The expedition of the Geolkom (Geological Committee) of the VSNX USSR carried out its work in Yakutia in 1925 under the guidance of the famous geologist V.N. Zverev. The main goal of the expedition was to justify the genesis and nature of gold placers in the Aldan River basin, to define the depth of occurrence of gold-bearing layers and the boundaries of their strike in plan. Such information was essential for a comprehensive and reliable assessment of the potential of a new, practically unexplored before, large alluvial gold deposit in the east of the country. The expedition to the newly discovered Aldan gold-bearing province was to play a decisive role in determining the future status and funding of the new gold mining enterprise. The importance of the goal being fulfilled became the reason for the accelerated preparation of the expedition, so its organization was unscheduled, carried out outside the programs and with special funds of the Geological Committee of the VSNX USSR. Based on the study of surviving archival sources, it was established that the expedition members carried out thorough geological, exploration and topographic work on gold deposits in the area of the middle Aldan River, including its right tributary basins. One of the main tasks of the expedition ruled by V.N. Zverev was the calculation of explored reserves and the assessment of forecast gold resources in the explored area. In general, the expedition fulfilled its tasks, managed to form a theoretically substantiated idea of the genesis of placer deposits of Aldan gold, provided materials that make it possible to bring the necessary scientific base under the general plan of exploration work for future placer gold mining along the Aldan River basin.
