This paper presents calculations of equilibria between nitrogenrich hot springs of the Baikal RiftZone (BRZ) and a secondary mineral assemblage (carbonate, fluoride, clay, zeolite, and other minerals). Theresults confirm the equilibrium–nonequilibrium character of the nitrogen spring water–rock system. Unlikeother water types, the system evolves under conditions of continuous incorporation of chemical elementsreleased from the host minerals into the newly formed secondary minerals. This allows the system to remaindynamically stable with no increase in salinity, despite continued water–rock interaction. The main factorresponsible for this state of the system is a deficiency of acids, i.e., high pH. As a result, the disturbance ofrelationships between concentrations of aqueous species compared to the starting composition of dissolvedsolids produces a deficiency of some elements (Ca, Mg, Fe, Al, etc.) and an excess of other elements (Na, Si,F, etc.).
