| 摘 要： | 通过对河南豫中黄土地区黄土剖面化学元素的深入研究认为:在该地区全新世中期风化成壤过程中,Al、Fe、K、Ti、Rb、Ba等元素在古土壤中相对富集,表现出残留富集的特征;而Si、Ca、Na、Sr等元素则在风化剖面中淋失。而Al、Na在成壤过程中因具有不同的地球化学行为,从而产生显著的分异现象,并且随着成壤作用的增强分异加剧。因此,Al/Na值在黄土剖面中的变化反映了风尘堆积物成壤强度的变化,能够作为成壤作用、气候变化的替代指标。

| Abstract: | The soil-forming process in Holocene and paleoclimate was illustrated by using the data obtained from the soil profile in the middle part of Henan Province.The magnetic susceptibility was measured on a sample of 10.0g of ground sediment with a MS-2B Magnetic Susceptibility Meter.Element contents were analyzed with a PW2403 X-ray fluorescence spectrometer.The analytical results indicated that Al,Fe,K,Ti,Rb and Ba relatively were enriched in the Paleosoil during the Holocene Climatic Optimum,while Si,Ca,Na an... |
