| 摘 要： | 在第四纪沉积物研究中,特别是现代沉积环境的研究中,沉积物的地球化学特征在分析物源和重建古环境等方面发挥积极的作用.通过采集了巴丹吉林沙漠不同区域、不同类型沙丘、不同地貌部位的沙样,分析了巴丹吉林沙漠沉积物的地球化学特征,得出巴丹吉林沙漠沉积物在矿物学上和沉积学上的成熟度较低,但是具有很好的均质性的结论.这一结论对于推断巴丹吉林沙漠沉积物的物源有很好的指示意义,同时对于研究巴丹吉林沙漠高大沙山的成因也有一定的线索意义.

| Abstract: | In the study of Quaternary sediments, especially the research of modern sedimentary environment, geochemical characteristics of sediments have a positive effect in the analysis of provenance and paleoenvironment reconstruction. We studied the geochemical characteristics of the sediments in different regions, different types of sand dunes in Badain Jaran Desert. The results show that the sediments in the Badain Jaran Desert is lower in mineralogy and sedimentology of maturity, but the homogeneousness is good. This conclusion has a good indication to infer the source of sediments in Badain Jaran Desert, also have certain reference significance for the research on the causes of. Badain Jaran Desert megadunes. |
