<p>Saline lakes represent closed, intracontinental basins that contain valuable evaporite mineral deposits. Analysis of the chemical composition of 267 saline lake sediment samples indicates that sodium sulfate compounds [Na₂Ca (SO₄)₂] exhibit the highest average concentration, accounting for approximately 16% of the composition. In contrast, magnesium sulfate (MgSO₄) displays the lowest average concentration, at 2.82%. These samples were obtained from 25 boreholes, each drilled to a depth of 10&#xa0;m. Sedimentological examination of the core samples identified four principal facies: green mud, black mud, red-brown-yellow mud, and salt crystal facies, with an additional twelve subfacies recognized. The facies are predominantly mud-rich, with high-crystal mud and salt crystal subfacies being the most prominent, generally occurring between depths of 1 and 4&#xa0;m. Mineralogical analysis revealed that these facies contain sodium sulfate minerals (including glauberite, thenardite, and mirabilite), magnesium sulfate minerals (hexahydrite and starkeyite), calcium sulfate minerals (basanite and gypsum), calcium carbonate (calcite), iron sulfate (amarantine), sodium chloride (halite), and clastic minerals such as illite and quartz. Cluster analysis delineated four distinct mineral assemblage groups: glauberite-thenardite-eugsterite, mirabilite-hexahydrite-basanite, amarantine-illite-quartz-calcite, and starkeyite-gypsum-halite. These clusters are indicative of formation under varying temperature and concentration conditions. The dominant chemical constituents of the minerals include Na₂SO₄ (16%), CaSO₄ (4.45%), NaCl (6.13%), and MgSO₄ (2.82%). The brine chemistry in the study area is characterized as Mg-Na-(Ca)-SO₄-Cl type, suggesting a capacity for precipitating diverse evaporite minerals such as gypsum, anhydrite, mirabilite, thenardite, glauberite, polyhalite, starkeyite, and halite.</p>
