摘    要:利用细颗粒热释光技术对渭南,会宁黄土剖面末次间冰期以来黄土-古土壤共15个样品进行了年龄测定。实验中,通过光晒退确定各个样品的残留热释光强度,应用残留热释光法测定等效剂量值,结果显示,在测定的热释光年龄数据基础一确定的两剖面的S0/L1、L1/S1、S1/L2界线年龄基本一致,并与SPECMAP深海氧同位素1/2、4/5、5/6阶段的界线年龄可较好对比,这也表明应用热释发光方法测定的末次间冰期以来

Abstract:Fifteen samples of loess and paleosol collected from the strata of the Weinan and Huining sections,Shaanxi Province,have been dated using the fine grain TL technique.By comparing the data of bleaching experiment with the TL measurements of the surface samples,we tested the residual TL level of the samples.Paleodose values were determined by the residual method.Based on the TL results from both sections,the ages of S0/L1,L1/S1 and S1/L2 stratigraphic boundaries are roughly coincident,and are generally consistent with the ages of 1/2,4/5 and 5/6 stage boundaries of the deep sea oxygen isotopes in the SPECMAP curve,this results reflect that it is reliable to measure samples of loess sequence of the last interglacial period by TL dating.
Keywords:loess  paleosol  TL  dating  the Weinan and Huining sections
