Abstract Determining the geochemical composition of mineral dust is highly effective for provenance tracing. Studies on the geochemistry of surface soils in the Pamirs, especially with different size fractions, are relatively limited. This study investigated the major, trace and rare earth elements (REEs) of surface soil samples collected on the Eastern Pamirs. The Fe/Al (~0.60), Mg/Al (~0.30) and Ti/Al (~0.05) ratios clearly highlight its clayey nature, while the La/Th (~2.60) and Th/U (~4.00) ratios indicate it is typical of the upper continental crust (UCC). The La-Th-Sc and Zr/10-Th-Sc ternary diagrams show the source rock of the Eastern Pamirs surface soil to be mainly felsic. The bulk and

东帕米尔高原表层土壤地球化学及其对慕士塔格冰芯尘源的影响

摘要 确定矿物粉尘的地球化学成分对于物源追踪非常有效。帕米尔高原表层土壤的地球化学研究相对有限，尤其是不同粒径的土壤。本研究调查了在东帕米尔高原收集的表层土壤样品的主要、痕量和稀土元素 (REE)。Fe/Al (~0.60)、Mg/Al (~0.30) 和 Ti/Al (~0.05) 比率清楚地突出了其粘土性质，而 La/Th (~2.60) 和 Th/U (~4.00) 比率表明它是典型的上大陆地壳（UCC）。La-Th-Sc 和 Zr/10-Th-Sc 三元图显示东帕米尔高原表层土壤的烃源岩以长英质为主。批量和
