Geochemical transformations of sulfur in salt lakes (Transbaikalia)

The water column in brackish and saline lakes hosts various forms of sulfur including sulfide (hydrosulfide), elemental, thiosulfate, sulfate sulfur. unequal distribution these reduced species indicates the presence two opposing processes - reduction oxidation newly formed hydrogen sulfide. scale varies among lakes, resulting differing proportions forms. bacterial ions is confirmed by a significant separation isotopes into ions, with lighter isotope accumulating former heavier latter. In most soda, chloride, brackish, salt principal process responsible for relatively low ion content. Additionally, an oxidizing environment sulfides host rocks provide additional sources sulfates, leading to formation sulfate-type lakes. specific types subtypes determined such as evaporation, dissolution aluminosilicates, reduction, sulfides. dominance contributes geochemical diversity
