| Abstract: | A preliminary study was carried out on the relationship between the element distributionin the Holocene stratum and palaeoclimate in the northern part of Taklimakan Desert basedon the14C datings. The results shaw that the palaeoclimate in this region has experienced thetemperate and a little wet climate in the early period,hot and dry climate in the middle periodand relatively cold and moist climate in the late period since 11 ka B.
