Water sources in the vicinity of Yakutsk

Abstract

We find a brief description of the sources in the vicinity of Yakutsk in the works of G. N. Ognev and I. M. Svetozarov. However, due to the specifics of their work, they could not give characteristics of these sources in connection with the geological structure of the area. In this article I will complement the previous ones researchers with new materials about sources obtained in 1939 as a result of the work of the hydrogeological team of the Yakut expedition of the USSR Academy of Sciences. Work was carried out on the right and left banks of the river Lena from the village Kachikatsy-Pokrovskoe to N.-Kangalas mines. The first group of sources is an indicator of sub-permafrost waters. These waters in the area are associated with Cambrian limestones and lower horizons of Jurassic sediments. Sub-permafrost waters are of undoubted practical interest both for the water supply of the city of Yakutsk (where the Cambrian lies at a depth of 450 m) and for the settlement currently underway in the Yakut Autonomous Soviet Socialist Republic. The second group of sources, associated with the upper aquifer, has no practical significance for water supply purposes. In conclusion, we present a map showing the general picture of the location of sources in the vicinity of the city of Yakutsk.
