Extensive field hydrogeochemical data and thermodynamic simulations demonstrate that the composition of lacustrine waters is controlled not only by evaporation but also by interaction between the waters and rocks. This interaction begins in the catchment areas of the lakes and continues in these lakes themselves, because the waters (regardless of their salinity) do not occur in equilibrium with many of the endogenic minerals. These processes are the most intense in soda lakes, as follows from the highest pH of their waters (9.0–10.7). These values provide evidence that these waters most intensely interact with primary aluminosilicates. The two processes responsible for sulfur behavior in these lakes are sulfate reduction and sulfide oxidation. Different geochemical environments produced in lakes of different type are favorable for the selective enrichment of some elements, which are mobile in these environments and whose concentrations can significantly increase.

控制东外贝加尔盐湖和咸水湖水成分的主要参数

大量的现场水文地球化学数据和热力学模拟表明，湖泊水的组成不仅受蒸发控制，还受水和岩石之间的相互作用控制。这种相互作用开始于湖泊的集水区，并在这些湖泊本身中继续存在，因为水（无论其盐度如何）与许多内生矿物质并不处于平衡状态。这些过程在苏打湖中最为强烈，其水的 pH 值最高 (9.0-10.7)。这些值提供证据表明这些水与原生硅铝酸盐相互作用最强烈。导致这些湖中硫行为的两个过程是硫酸盐还原和硫化物氧化。
