Such calibrated ages, given by CALIB versions, are close to the calendrical 'true' ages in fall play. Thus, this is beneficial to better reconstructing the regional geochronologic history since the late Late Pleistocene and such calibrated ages can be compared directly with the archaeological evidence and other absolute dating results as well.

We conducted high-density resistivity surveying combining with boring data across F1 and F3. The results show that F1 cut the 3rd terrace which formed in late Pleistocene, and the last activity was extensional normal slip by echelonment falling down toward the basin. F3 stroke zigzag and cut the 1st alluvial-proluvial terrace and Holocene stratum with large displacement of fault and wide fracture zone in bedrock, and the last activity is the continuous falling around the fault.

In order to explore the grain-size distribution characteristics and geo-genetic types of land desertification in Mo Us desert, the research on the grain-size characteristics of sediments since late Pleistocene has been carried out in the desert area and neighboring area such as inside desert, sand covered loess plateau, loess plateau and river valley. The research result shows that sediments of different geologic genetic types are the fundamental material source of sandy desertification in these areas and the distinguishing of different types of the sediments is the theoretical basis of classification of different geogenetic type of sandy desertification. The contribution of different geological roles on the land desertification and its significance to prevent and deal with the land desertification have also discussed.
