黄土高原的风成沉积序列是晚新生代古气候变化的最佳大陆档案之一。黄土序列中的磁化率（MS）和沉积粒度（GS）等古气候指标的变化是评价古气候波动时间序列的标准工具，而这些变化与季风变化在多千年时间尺度上具有显著的相关性。季风动力学与太阳日射、冰量变化和海洋-大气能量交换的节律有关（Ding等人，1994）。最近，Ao et al.（2016）发表了一个800万年的增强中新世-上新世季风增强模型记录，该模型与南极冰盖的逐步增加有关。其气候变化评价是基于所谓的新石楼红粘土剖面的年龄模式，位于石楼县东南约13公里（山西省）的东部CLP。新石楼剖面距离石楼剖面1.1公里，石楼剖面已经使用磁性地层学确定为1100万年（Xu等人，2009年）。2015年，TA、VAK和RZ重新检查了石楼剖面的磁性地层、MS和GS数据，并应用气候代用指标中记录的轨道周期性分析（Anwar等人，2015年）。在建立了一级磁性地层学的基础上，
Eolian sediment sequences on the Chinese Loess Plateau (CLP) are one of the best continental archives of paleoclimate change in the late Cenozoic Era. Variations in paleoclimate proxies in loess sequences, such as magnetic susceptibility (MS) and sedimentary grain size (GS), are standard tools to evaluate the time series of paleoclimatic fluctuations that bear a remarkable correlation with monsoon variability on multimillennial timescales. Monsoonal dynamics are linked to the rhythms of solar insolation, ice volume changes, and ocean–atmosphere energy exchange (Ding et al., 1994).Recently, Ao et al.(2016) published an 8 Myr record of the enhanced Miocene–Pliocene monsoon intensification model linked to the stepwise increase of the Antarctic ice-sheet. Their climate change evaluation is based on the age model of the so-called New Shilou red clay section situated∼ 13 km southeast of Shilou County (Shanxi Province) on the eastern CLP. The New Shilou section is situated∼ 1 km from the Shilou section, which was already dated at 11 Myr using magnetostratography (Xu et al., 2009). In 2015, TA, VAK, and RZ re-examined the magnetostratigraphic, MS and GS data for the Shilou section applying the analysis of orbital periodicities registered in the climate proxies (Anwar et al., 2015). After creating a first-order magnetostratigraphic correla-
