Abstract
A three-dimensional digital hydrogeochemical model of the area was created. Sedimentogenic methane weakly saline alkaline waters are presumably widespread in the deep part of the section of the Baikal artesian basin. A stable association of lithophilic components (Li, B, Na, Si, K, Rb, Hf, W) in maximum anomalous concentrations (Хav.+3σ) was revealed in the thermal water of the Central Eco-Zone (CEZ) of Lake Baikal, which made it possible to identify areas of deep groundwater recharge. It was shown that free gases in Lake Baikal in areas with a thick cover of Cenozoic sedimentary rocks had a methane and nitrogen-methane composition, while in other places their composition was nitrogen. The isotopic composition of natural waters was studied.
