We have observed the structure of these dune sands and analyzed the grain-size,surface textural features and several main chemical elements of them,the results showed that:(1) these dune sands have some eolian structure characteristics which are similar to the recent dune sands;(2) they are also similar to the recent dune sands in grain-size components,and parameters of Mz,?滓,Sk and Kg,as well as in several main chemical components;(3) the scatter plots of Mz-?滓,SiO2-Al2O3+TOFE and the probability curves of grain-size showed that these paleo dune sands are different from paleosols and fluvio-lacustrine facies but are consistency with recent dune sands;and(4) the quartz sands have well roundness and some surface textural features such as dish-shape pits,crescent-shape pits,pockmarked pits,upturned cleavage plates,siliceous precipitates and siliceous crevasses,indicating that they had been carried for a long time by the wind.
