摘要
By studying on correlation between magnetic susceptibility, TOC,CaCO3,Fe2O3 and grainsize component of 73 samples from the paleosand-paleosol sedimentary section of Xinjiang Takermohuer desert,according to OSL date,the authors discussed mechanism of magnetic susceptibility change and paleoclimate significance.The results were that:the correlation between χlf and percent content of 16～250 μm component was positive,coarse component percent content affected the change of χlf.Climate change of research area is simliar to the other regiones during late holocene,and it was related to the temperature change events of surface sea-water in north Alantic Ocean.The climate change was typical westerly climate model,warm-dry or cool-wet.
