Equilibrium of West Mongolian Soda Lake Waters with Carbonate and Aluminosilicate Minerals

This article presents data on the chemical composition of soda lakes in western Mongolia, describes and graphically represents the equilibrium of the water with carbonate, sulfate, and aluminosilicate minerals. We conclude that the soda lakes are products of water-rock interaction that resulted in precipitation of carbonate minerals under conditions of high water exchange and arid climate, and has lasted a geologically long time.
