The results of the study of carbonate-containing bottom sediments from the shallow brackish Lake Itkul (Western Siberia) are presented. The research methods include X-ray diffractometry (XRD), IR spectroscopy, laser granulometry, elemental analysis, etc. By the modeling of XRD carbonate profiles with the Pearson VII function, carbonate phases were identified and their quantitative ratios were determined. By the comparing of carbonate record with lithological, geochemical data in a dated sedimentary section, the evolution of the lake basin in the Holocene caused of climatic changes was reconstructed. Mineralogical signals of the global climatic event known as Bond event 4 in the South of West Siberia have been discovered.

AbstractHigh-resolution climate archives of the Late Holocene are essential in the study of paleoclimatic dynamics and for understanding the importance of natural and anthropogenic influences on past and future climate changes. Here, we present well-dated X-ray fluorescence scanning records retrieved from a varved sediment core from Lake Kusai. These records show the decadal- to centennial-scale paleoclimatic variability of the northern Qinghai-Tibetan Plateau over the last 2000 yr. Ca is mainly related to the precipitation of authigenic carbonates and is a proxy for temperature changes. The Ca record of Lake Kusai is well-correlated with the variations and periodicities of solar activity. Therefore, solar output can be suggested as being the predominant forcing mechanism of decadal- to centennial-scale temperature fluctuations over the last 2000 yr. The evolution of effective moisture was inferred from the log-ratios of Rb/Sr, which demonstrated synchronous changes with the typical Indian summer monsoon record from Dongge Cave. These results indicate that the decadal- to centennial-scale effective moisture evolution of the northern Qinghai-Tibetan Plateau is mainly influenced by the Indian summer monsoon. Additionally, we have not found the evident periodicities of solar activity in our effective moisture record over the last 2000 yr.

Abstract The article presents the characteristics of the relief of the Rypienica channel (the Dobrzyń Lakeland, North Poland) and the postglacial development of vegetation in this area. The detailed analysis of the organic sediments of the peat-bog vegetation of the Rypienica channel documents the development of vegetation since the beginning of the Holocene until the younger part of the Subatlantic period. Holocene sediments record changes in the local vegetation of this peat-bog brought about by fluctuations in climate, changes in local hydrological conditions and the impact of human activity.
