充分认识元素和同位素在不同环境条件下的地球化学行为，是运用元素和同位素示踪环境变化的前提。对来自于黄土高原的黄土、古土壤和红粘土样品的宇宙成因核素10Be测量和化学成分分析，以及各种化学淋溶实验表明：10Be主要以吸附状态赋存于粉尘沉积物粘粒矿物的表面，部分已结合进自生的粘土矿物中；在粉尘沉积物风化过程中10BC与9Be和Al的活动性相似，基本没有发生迁移，其原因是连续沉积的粉尘含有大量的碱性物质，阻止了10Be的解吸附和淋滤；沉积和风化作用导致了10Be浓度与化学指标在黄土－古土壤和红粘土剖面中的协同变化。
Fully understanding the geochemical behavior of elements and isotopes under different environmental conditions is a prerequisite for tracing environmental changes using elements and isotopes. The 10Be measurements and chemical compositions of the cosmogenic nuclides from loess, paleosol and red clay samples from the Loess Plateau, as well as various chemical leaching experiments show that 10Be mainly occurs in the adsorbed state on the dust deposit clay minerals Surface and some have been incorporated into the spontaneous clay minerals. The activities of 10BC and 9Be and Al are similar during the weathering of the dust deposits, and the migration is basically absent due to the continuous deposition of dust containing a large amount of alkaline substances, preventing 10Be desorption and leaching; sedimentation and weathering led to the 10Be concentration and chemical indicators of the synergistic changes in loess-paleosol and red clay profiles.
