内蒙古大兴安岭南段表生地球化学作用特征

Hypergenic Geochimical Process Characteristics in the Southern of Daxinganling, Inner Mongolia

本文对内蒙古大兴安岭南段表生介质的形成过程、层位结构、粒级分布、元素在各粒级段的含量、元素在表生环境中的赋存形式、次生分散富集规律等特征作了初步分析研究。对本地区地球化学异常的解释推断及今后工作具有一定的参考意义。

The paper analyses hypergenic mediums forming process, horlizon texture, grade distribution and occurrence mode at hyperinic enrichment rule in the southern of Daxinganling, Inner Mongolia. In this way, these explanation of geochemical anomalies could have reference signification in the area.
