Method of constant equilibrium (physicochemical) is based on the search of such water composition, at which activities or concentrations of components would be tied between themselves by equilibrium constants, according to the mass-action law. This method is commonly used in physical chemistry, especially in the chemistry of complex compounds, as it solves most of their problems. Its application in hydro-geochemistry is due to the fact that computer programs developed on its base are simpler and, as a rule, take less time for calculations. 

From the position of hydro-geochemistry minerals are treated as pure substances with activity equal to 1. 

The applied value of cosmogenic isotopes in hydro-geochemistry is associated mostly with their use for the evaluation of the Hfe time of surface origin water in the subsurface, which will be dwelt on later.

This section presents a discussion of the fundamentals of three major solute isotope systems carbon, nitrogen, and sulfur. Recent comprehensive reviews of the geochemistry of several other solute isotope tracers in hydro-logic systems include those by Faure (1986),... 

However, there is very little study on the hydro-geochemical and isotopic characteristics of Ordovician limestone water in our study area. Therefore, the purpose of this paper is to study the hydrology-geochemistry, isotope and water circulation characteristics of Ordovician limestone groundwater, and lay the foundation for discriminating the water source of mine water inrush.
