青藏高原东北部的西宁盆地紧邻柴达木盆地戈壁沙漠,沉积了厚层的、序列完整的黄土物质,对其进行研究可望得到高原古气候演化信息。通过对西宁盆地盘子山黄土剖面酸溶相Sr、CaO含量变化的测试分析,获得了自末次间冰期以来多次不同时间尺度变化的信息,证明Sr、CaO可以作为该地区黄土研究更为灵敏的气候代用指标。
The Xining basin in the northeastern Qinghai-Xizang Plateau is close to the Gobi Desert in the Qaidam Basin, depositing a thick, well-sequenced loess material, and is expected to obtain paleoclimatic evolution information from the plateau. Through the test and analysis of the acid-soluble Sr and CaO content in the loess section of the Panzishan, Xining basin, the information of multiple time scales since the last inter-glacial period was obtained. It is proved that Sr and CaO can be used as the loess research more sensitively Climate proxy indicators.
