The springs of the Yakutsk city vicinity
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 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 Lena River from the village of Kachikatsy-Pokrovskoye to the N. Kangalas mines. It is easy to see that the first group of springs is an undeniable indicator of subpermafrost waters. These waters are connected in the given area with Cambrian limestones and the lower layers of Jurassic deposits. Subpermafrost waters are of undoubted practical interest both for the water supply of the city of Yakutsk (where Cambrian lies at a depth of 450 m) and for the population of the Yakut A.S.S.R. The second group of springs, which is connected with the upper water-bearing layers, has no practical purpose for water supply.
