Paper compares the regularities of hydrogeochemical and geodynamic conditions in the areas of the central part of the West Siberian megabasin adjacent to the Koltogorsk-Tolkino suture zone. A significant difference of the spatial regularities for the individual components content and the general mineralization of groundwater is established, as well as for the hydrogeochemical conditions of the Aptian-Albian-Cenomanian, Neocomian and Jurassic aquifers. This characterizes the diverse impact of various geological and hydrogeological processes on the individual components content of the water-soluble groundwater complex. The absence of according between hydrogeochemical and tectonic conditions at the initial period of basin development has been established. The existence of connections for recent or active tectonic processes with the distribution of groundwater mineralisation for all aquifers is revealed.
