Experimental observation of deep crust fluid-NaCl aqueous solution at elevated temperatures and pressures and its significance

It is possible to observe a “critical phenomenon”. In some of our experiments an “explosion” almost constantly occurred at the interface between the liquid and vapor phases, making the interface obscure, and a continuous transition between the two phases could be found. By a visual microscope it was found that in the two-phase immiscible field near to the critical state the vapor phase and liquid phase compose a crystal structure geometry. It is a special solution structure that was found under a microscope. This discovery is important for us to understand the reason of increasing electronic conductivity of NaCl aqueous solution with respect to temperatures and pressures. And also, it will be easy to interpret the variation of electronic conductivity in the earth crust.
