Title: Study on the Characteristics of the Geochemical Elements and Paleoclimate Changes in Lake Barkol,Xinjiang Since About 9.0 cal ka BP
Abstract: Geochemical elements analysis of BLK-1,retrieved from Lake Barkol,NW China,was carried out by using SPSS,and envoronmentally geochemical elements components can be easily identified according to the variations in the Load of R(Q)-type factors.In addition,we used some other proxies as the auxiliary factors in the analysis process.The results have shown that the paleoclimate of Lake Barkol has a drought trend overall,although it has experienced an alternating climate process(cold-moisture and warm-dry)since 9.0cal ka BP,and the history of paleoclimatic changes was reconstructed as follows:(1)9.0-7.0 cal ka BP,the palaeoclimate was dry;(2)7.5-5.8 cal ka BP,the palaeoclimate was warm and humid,we suggested it's the Holocene Optimum period of study area;(3)5.8-3.0 cal ka BP,the palaeoclimate was dry;(4)3.0-1.0 cal ka BP,the palaeoclimate was warm and humid;(5)1.0-0 cal ka BP,the palaeoclimate was dry.
