摘要Dating techniques including gypsum dissolution in water, iron hydroxide co-precipitation with uranium and thorium and mass spectrometric determination have been investigated in this note. The ages of the gypsum samples in a CK core from Luobubo lacustrine sediments are in the range of (12.85 +/- 0.21) kaBP (4 m distance from the top core) to (153.2 +/- 7.2) kaBP (49 in distance from the top core) with the relative errors of +/-1.6% - +/-4.7%. It indicates that the sedimental environment of the CK core was situated in the middle-late Pleistocene and Holocene periods, corresponding to 1-6 stages of oxygen isotopes in the abyssal sediments and included much information from last interglacial to Holocene warm periods.
