通过萨拉乌苏河流域下游酒坊台剖面较高精度的主元素氧化物及比值分析,结合测年结果,恢复了流域内晚更新世以来气候环境演化历史,指示了冰期-间冰期旋回在该区有很好的沉积响应。尤其是末次间冰期对应的萨拉乌苏组,各主要指标与深海氧同位素5阶段(MIS5)有明显的对应关系。同时,针对剖面中主元素的地球化学特征,指出古地理特征、气候条件、元素的赋存状态对流域内地球化学特征有明显影响。
Through the analysis of the oxide elements with higher accuracy and the ratio analysis of main elements in the section of Liupatetai in the lower Sarawoo River basin and the dating results, the evolution of the climate environment in the basin since the late Pleistocene was restored, indicating that the glacial-interglacial cycles were at The area has a good deposition response. Especially the Salau-Wusu Formation corresponding to the last interglacial period. The major indices have a clear correspondence with the deep-sea oxygen isotope 5 (MIS5). At the same time, according to the geochemical characteristics of the main elements in the profile, it is pointed out that the paleogeographical features, climatic conditions and the occurrence of elements have a significant impact on the geochemical characteristics of the basin.
