资源简介：
通过对渭南黄土剖面蜗牛化石记录的研究，并结合长武和洛川剖面，探讨末次冰期晚期这一地区气候变化的特点。研究结果表明末次冰期晚期时黄土高原的气候是极不稳定的，其变化趋势与东北太平洋Tanner孔有孔虫含量及GRIP2冰芯氧同位素记录有很好的可比性，从而为探索黄土高原区末次冰期气候不稳定性的原因提供了新的思路。
By analyzing the snail fossil records from the Weinan Loess Profile and combining with the Changwu and Luochuan Profiles, this study investigates the characteristics of climate change in this region during the late Last Glacial Period. The results show that the climate of the Loess Plateau was extremely unstable during the late Last Glacial Period, and its variation trend shows strong comparability with the foraminiferal abundance in the Tanner Core of the Northeast Pacific and the oxygen isotope records from the GRIP2 ice core, thus providing new insights for exploring the causes of climate instability in the Loess Plateau region during the Last Glacial Period.
