Abstract
The authors propose a new approach to creating high-resolution paleoclimatic reconstructions based on lithological and geochemical study of lake sediments. Scanning X-ray analysis on synchrotron radiation with 100 micron spatial resolution is used to obtain the time series. Transfer function relating the variation of the geochemical composition of sediments with the climatic parameters is calibrated according to the instrumental meteorological observations (data for the last 100–150 years) and approximated by the all depth of core. Quantitative paleoreconstruction on a timeline with annual steps is used to search for natural climatic cycles of various periods ranging from several years to a few thousand years. Found climatic cycles are used to create a forecast function, which allows to carry out the interpolation in the future. The proposed method may be considered as analytical microstratigraphy of lacustrine sediments and is tested on a model object – Lake Teletskoye (Altai Mountains) and allows to obtain paleoclimatic information of high quality.
