摘    要:利用细颗粒热释光技术对陇西黄土高原会宁黄土剖面末次间冰期以来黄土、古土壤的8个样品进行了年龄测定,并在此基础上分别利用线性内插和多项式回归方法建立了会宁剖面深度-年代时间模式,以2种模式计算的S0/L1、L1/S1、S1/L2界线年龄与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,这为末次间冰期以来会宁地区古气候演化的深入研究提供了基本时间框架。

关 键 词:会宁黄土剖面    热释光    时间模式    末次间冰期

Abstract:Eight loess and paleosol samples collected from the strata along the Huining section in Shanxi Province were dated by means of the fine-grain TL technique. On the basis of the TL results obtained from this section,two methods were applied to develop the timescales for the Late Quaternary Huining section. The first age model was established by polynomial regression,whereas the second age model used TL age controls interpolated by a sedimentation rate. The ages of S0/L1, L1/S1 and S1/L2 stratigraphic boundary from the two age/depth models for the Huining section are generally consistent with the ages of 1/2, 4/5 and 5/6 stage boundary of the deep-sea oxygen isotopes in the SPECMAP curve.
Keywords:Huining loess section  TL  timescales  Late Quaternat
