摘要
研究东天山土屋—延东成矿带的土壤垂直剖面中,盐类明显淀积区段的水溶相、硫酸盐相和碳酸盐相元素分布,初步推断了由盐类组成的碱性地球化学障对土壤中元素分布的影响。在东天山地区干旱荒漠景观条件下,碱性地球化学障对表生带元素分布和存在形式的影响十分明显,各段碱性地球化学障因Ca、K、Na等盐类淀积部位的不同而出现了不同类型,并使元素在剖面上的分布产生差异。
This paper studied element distribution in aqueous phase,sulfate phase and carbonate phase in the vertical profiles of soil for the salt section along the Tuwu-Yandong metallogenic belt in Eastern Tiansan.The authors revealed the mode of the influence of alkaline geochemical barrier composed of alkaline salts on the distribution of elements in the soil.The existing forms and distribution of elements in the supergene zone is obviously influenced by the alkaline geochemical barrier.Ca,K,Na are in different positions of salt deposition,and the sections of the alkaline geochemical barrier have different types,so that the distribution of elements differs in the vertical profile of soil.
