Abstract: ESR dating, suited for the Quaternary samples, has been developed abroad in recent decade.The determinations of deer horn, lamprotula, stalagmite, loess, coral and shell samples by ESR dating hawe been described in this paper.The ESR age of deer horn from Xianshui River and lamprotula from Nihe-wan are 1,25 and 1.22-1,37×10⁶ yrs,respectively, which are concordant with that of their stratigraphy.The average of the ESR age of the stalagmite from the fourth place cave of Choukoutien is 6×10⁴yrs, which is close to 6.5×10⁴ yrs of the 230Th/234U age.The ESR age of the loess from S-7 layer of Luochuan profile is 7.38×10⁵yrs corresponding to that by thermoluminescence and paleo-magnetic methods.The ESR age of the coral at South Sea is 4.09±0.61 dropped in the range of 5.0±0.2 and 3.75±0.19 ka by 230Th/234U and ¹⁴C methods, respectively, uhile much near to the ¹⁴C age.The ESR age of the shell at Baoyu island is 1.66±0.25 ka, which concords with 1.69±0.09 Ka of the ¹⁴C age.The ESR age determinations as mentioned above show that the method of ESR dating will be a powerful tool of the studies on the Quaternary chronology.
