摘要
表生介质中铜的赋存相态对其表生异常的发育有重要意义。通过对敖格道仁诺尔铜与金属的矿化区内土壤及湖积物中铜的七种赋存相态的分析研究 ,认为在土壤剖面上的不同层位之间 ,铜的赋存相态存在差异 ,而这种差异又会随近矿地段和矿体上方土壤空间位置的不同有所变化。铜的这种赋存相态特征受研究区地理景观条件、土壤结构类型、土壤环境的化学物理参数及铜的表生地球化学性质等内外因素制约的。
The existing phase of copper in supergenic medium is very important to the development of supergenic anomaly. On the base of analysis and study on seven copper's existing phase in soil and lacustrine sediment, it is proved that the copper's existing phase are different between each layer in soil vertical section, and the differences change with the different location of soil in near mineral deposit and over ore body. The distributing characteristics of copper's existing phase depends on some factors, such as geographical landscape condition of ore region, soil types of structure, physical and chemical coefficient of soil environment and the copper's supergenic geochemical nature, and so on. The further study on the controling factors is important basis of researching the formation mechanism of supergenic anomaly and evaluating it.
