Zusammenfassung:For the first time, using the example of a key object of the peat river valleys of the Kuznetsk Alatau occupied by spruce forests, it is shown that swamp waters are clearly differentiated by the content of the main ions due to forest–peat fires. Swamp waters objectively form three groups: (1) waters of the original type of mineral nutrition (fresh, soft), (2) waters of peatland covered by a medium fire (fresh, hard), (3) waters of peatland covered by a high fire (slightly saline, very hard). Magnesium ions and bicarbonates have the highest discriminating power (95%) in the determination of swamp waters. The swamp waters of the post-pyrogenic peatland do not lose the ratio of the main ions, which is similar to waters of the original type, and retain the hydro-carbonate calcium–magnesium composition.
