e than 20 loess sections distributed at Ping ′in,Qingzhou,Linqu, Zibo andPenglai of Shandong Province,Jiashan of Anhui Province and several sites near Nanjingof Jiangsu Province have been measured.Among them,the Fujiazhuang section atQingzhou is the best one,and can be regarded as a typical section in the study area. TLdating results show that the lowest layer of the Fujiazhuang section is L_9,with an age of0. 8Ma B. P. ,and its toppest layer(L_1) has an age of 0. 005 Ma B. P. ,and that the ageof the lowest layer(L_6)of“Xiasu earth”section in Nanjing is 0.63 Ma B. P. , Based ondating results of all sections in the area,a chronologic sequence for the area can be estab-lished as follows:L_1=61一l43,L_2=158一242,L_3=250一324,L_5=440一470,L_6=492一629,L_8=724 and L_9=792ka B.P. respectively. The chronologic sequence of the area hasa close similarity to that of the Loess Plateau.
