英文摘要	The U-series component-dating method has been employed to date the sediment core B(1)94 from Balikun Lake. Th-230/Th-232 and U-234/Th-232 ratios in various components of the samples dissolved in different concentration acids were measured respectively. The results indicate that there is a good relationship of the isotopic ratios between the solutions and the residues, and that uranium and thorium isotopic fractionations did not occur during acid leaching. Based on the U-series ages obtained by using component-dating method, a 144-ka time sequence was established corresponding to the upper 25-m interval of the B(1)94 core, which is in agreement with palaeomagnetic dating results. The fact that the palaeoclimatic and palaeoenvironmental record labeled with U-series ages is correlative with the deep-sea delta(18)O SPECMAP also demonstrates that the U-series component-dating method can be used to date lake sediments.
