Abstract This paper is a review of the saline endorheic lakes of the Northern Kazakhstan, with the provided data on chemical composition of their waters and sediments, diversity/uniformity, mineral precipitation sequences and brine evolution. Study saline lakes are located in the Ishim steppe geographical unit of the southern Western Siberia and are ancient closed basins. The lakes are of Cl–Na and Cl–Na–Mg chemical types (the most saline Zhalauly lake (428 g/L) is Cl–Mg type), their pH values vary from 6.0 (Kalibek lake) to 9.1 (Shureksor Lake). The common trend for the lakes chemical state is a low calcium concentration with high values of sodium, i.e. calcium
