The Role of Shear Tension Structures in Subvertical Filtration of the Water Drive System of the Moscow Artesian Basin

Abstract

Presents the results of a study in which a local dome-shaped piezometric surface of the Podolsko- Myachkovski aquifer complex was revealed in the western part of the Moscow region, the central part of which coincides with an elongated swampy depression. The results of morphostructural and geological-structural analyzes show that the depression may have a tectonic origin. Using the method of mathematical modeling, it is shown that the formation of a groundwater recharge dome is possible only due to the presence of a zone of increased permeability of the Callovian-Kimmeridgian waterproof complex, formed during the development of faults.
