Abstract

Data of hydrogeochemical studies of the Ivano-Arakhleiskie Lakes have been collected for different climatic phases of territory moistening. Three groups of water bodies are identified, including ultrafresh, fresh, and slightly saline. The lake waters are shown to differ by mineralization, chemistry, and pH. The least mineralized waters are found to be of HCO₃-Ca type, which, at an increase in water salinity and pH, changes to HCO₃-Mg and further to HCO₃-Na, and finally, to SO₄-Na. The changes are found to be larger in small slightly saline lakes and smaller in large ultrafresh lakes. The major processes that control the hydrogeochemical diversity of lakes are identified, including the interaction between water and aluminosilicate rock, sulfate reduction, oxidation of sulfides, and evaporation concentration.

不同气候阶段伊万诺-阿拉赫莱斯基湖的水化学

摘要

已经收集了伊万诺-阿拉赫莱斯基湖的水文地球化学研究数据，用于领土湿润的不同气候阶段。确定了三组水体，包括超新鲜、新鲜和微咸水。湖水在矿化、化学和 pH 值方面有所不同。发现矿化最少的水是 HCO ₃ -Ca 类型，随着水的盐度和 pH 值的增加，会变为 HCO ₃ -Mg，进而变为 HCO ₃ -Na，最后变为 SO ₄-呐。发现这些变化在小型微咸湖中较大，在大型超淡水湖中较小。确定了控制湖泊水文地球化学多样性的主要过程，包括水与铝硅酸盐岩之间的相互作用、硫酸盐还原、硫化物氧化和蒸发浓缩。
