Abstract. Comparative hydrogeochemical studies of groundwater in the Ulaanbaatar reservoir and those in the coast of Lake Baikal show significant difference between hydrogeodynamic processes of these areas, the earlier generation of U-isotopic and Si–Na–Li-temperature anomalies in the Ulaanbaatar groundwater reservoir and the later in those of the Baikal coast.

Keywords: groundwater, monitoring, Na/Li, ²³⁴U/²³⁸U, ²³⁴U, earthquake, friction clay, Baikal, Mongolia.
