| Abstract: | Takermohur desert is located in Yili valley of west Xinjiang,which is also situated at semiarid desert geochemical environment in mid-latitude westerlies of northern hemisphere.In the center of the desert,we observed a continuously sedimentary profile(with 3.6m outcropped thickness) which is formed with alternative aeolian layers and paleosol layers.On this profile,we collected 72 samples with 5cm equal interval and 3 samples for OSL dating.In the laboratory,we tested 18 trace elements content with X-ray fl... |
