Isotopic compositions of chlorine in brine and saline minerals
- 34 Downloads
The above results indicate that37Cl/35 C1 ratios in saline minerals are higher than those in brine due to chlorine isotopic fractionation during evaporation.37Cl/35 C1 ratios of salt lakes brine reflect the change in hydrochemical condition. The chlorine isotopic composition of saline mineral is associated with environment. Therefore, chlorine isotope may be used to trace evolution of salt lakes and the environment.
