| 摘 要： | 湖润锰矿床锰矿石包括两种类型：原生破酸锰矿石和次生富集的氧化锰矿石。本文主要结合该矿床的分布与地质特征，研究了微量元素和稀土元素的地球化学特征。研究结果表明，从原生带到氧化带，随着氧化程度的升高，与Mn成类质同像的Co、Ni、Pb和Zn等微量元素的含量都随着锰含量的增加而增加，其富集系数也相应地增大；同时，稀土元囊的总量也呈增加趋势，而且氧化带比原生带更富轻稀土元素。

| Abstract: | The Hurun manganese ore deposit consists of primary manganese carbonate ores and secondary manganese oxide ores. The geochemical characteristics of trace and rare-earth elements are studied in conjunction with the distribution and geological characteristics of the ore deposit. The results show that Co, Ni, Pb and Zn may isomorphically replace Mn with increasing oxidation degree. Their contents will increase with increasing manganese content. The total amount of the rare-earth elements tends to increase from the primary zone to the oxidation zone, and the light rare-earth elements are more enriched in the oxidation zone. |
