abstract = "We present the results of study the Holocene sediments of Itkul Lake, a shal low brackish lake with carbonate sedimentation, located in the eastern part of Baraba lowland (Southwestern Siberia, Novosibirsk Region). A 1.8 m thick core of the Holocene (7.914C yr) sediments of Itkul Lake has been studied. Based on the geochemical and lithostratigraphic properties of the bottom sediments, we have established the following stages of the lake evolution: (I) the beginning of sedimentation, 7.8–7.014С ka; (II) extreme shallowing with a probable complete drying, ~7.0–5.514С ka; (III) rise in the water level, ~5.5–4.314С ka; (IV) repeated shallowing, 4.3–2.8 14С ka; and (V) subsequent watering, 2.8–0 14 С ka. At present, the lake again tends to shallowing.",
