资源简介：
将黄土10Be浓度记录与SPECMAP δ18O曲线匹配，产生一个新的15万年黄土堆积的连续10Be时标。根据这一新的时标所获得的黄土堆积速率变化曲线很好地显示了0.02Ma及0.06Ma B.P.两处的峰值，与西北太平洋V21-146孔沉积物和南极东方站冰芯中所观察的结果十分一致。即与末次间冰期以来几次寒冷的时期相对应。
By matching the loess ¹⁰Be concentration record with the SPECMAP δ¹⁸O curve, a new continuous ¹⁰Be chronology for 150,000-year loess accumulation was established. Based on this new chronology, the variation curve of loess accumulation rate clearly exhibits two peaks at 0.02 Ma and 0.06 Ma B.P., which is highly consistent with the observations from the sediments of core V21-146 in the northwestern Pacific Ocean and the ice core from the Antarctic Vostok Station. This corresponds to several cold periods since the last interglacial period.
