Study of Holocene glacier degradation in central Asia byisotopic methods for long-term forecast of climate changes

This article presents a summary of our studies of Holocene moraines and glaciers of the Tien-Shan, Pamir, and Himalaya mountainswith the purpose of providing pattern regularity of the Holocene glaciation decomposition. We developed a method for obtainingreliable radiocarbon dating of moraines with the use of autochthonous organic matter dispersed in fine-grained morainicmaterial, as well there were shown new possibilities of isotope-oxygen and isotope-uranium analysis for the Holocene glaciationsdynamics. We found that Holocene glaciations disintegrate stadially according to the decaying principle, and seven main stagesmay be distinguished. We achieved the absolute dating of the first three stages, identifying these periods as 8,000, 5,000, and 3,400years ago. The application of the above-mentioned isotope methods of the Holocene glaciations and moraines study will allow researchersto improve the offered model of the Holocene glaciations disintegration; it will be great contribution to salvation of theproblem of long-term climatic and glaciations forecast.
