| 中文摘要: |
| 湘西北锰矿资源丰富，主要为赋存于南华系大唐坡组下段黑色页岩中。通过对烂泥田锰矿床研究表明，成矿物质来源为深源富锰热液及古陆等多种来源，锰以氧化物或氢氧化物的形式沉淀，菱锰矿的生成与藻类活动密切相关，属于化学-生物化学沉积成因矿床。湘西北地区南华系内自下而上构成钼钒矿→磷矿→锰矿→铅锌矿组成的矿床组合成矿系列，可进行综合找矿、综合评价、扩大矿床经济效益。 |
| 英文摘要: |
| Mn deposit occurs in the balck shale rock of Datang Po Formation, Nanhua system. there are abundanct Mn resources in northwest Hunan. According to the study of Lannitain Mn deposit, the ore materials are multi-sourced from the ancient land, the deep seated Mn-rich. Some Mn is precipited as oxide and hydride. Rhodochrosits is closely related to activity of algae. Genetically, the Mn deposit is a chemical-biochenical sedimentary deposit. From bottom to top the Nanhua system shows Mo-V-P-Mn-Pb-Zn metallogenic series thus it should be comprehensively prospected and assessed to maximize the economic profit. |
