Abstract
The results of a geochemical study of groundwater in an area of dawsonite mineralization are reported. The studied groundwater has a sodium bicarbonate composition, with pH 7.3-9.2, and a salinity of 0.4-7.2 g/L. The equilibrium conditions in the water with respect to dawsonite, calcite, gibbsite, kaolinite, montmorillonite, quartz, albite, anorthite, and analcime were investigated. A comprehensive consideration of groundwater composition and ore-forming properties of the water-rock system led to the conclusion that dawsonite is a product of aluminosilicate rock weathering. However, this mineral is formed only under conditions of reduced water exchange providing a long-term water-rock interaction and accumulation of sufficient amounts of Na +, OH -, HCO 3 -, CO 3 2-, and Al(OH) 4 -.
