aquifer basin
2.Ac cording to the increasing of TDS, Ca2+ and 40Ar/36Ar values of ground brine and the decreasing of δD values from the outer zone to the inner zone with deepening of the aquifer in large - scale artesian basin, it can be seen that the poorness in 2H and the richness in Ca2+ may be the characteristics of the hydrosphere at the beginning and proton had beed lessened gradually from the hydrosphere during the planet - earth history, and the ground brine, salt and hydrocarbon mines derive themselves from the upper mantle initially.
