| 中文摘要: |
| 广西宜州市龙头锰矿经过近60年的开采，现面临严重的资源危机，急需开展深部找矿工作。该锰矿为桂西北地区较为典型的海相沉积型矿床，受岩相古地理、地层、构造以及锰质来源等控矿条件制约，通过对矿区控矿因素的综合分析，得出矿区深部及外围具有较好的成矿地质条件，并类比邻近里苗锰矿区的最新勘查找矿成果，认为矿区深部及外围具有较好的找矿潜力，值得进一步开展深部找矿工作，矿床规模有望达到大型。 |
| 英文摘要: |
| After nearly sixty years of mining, now the Longtou manganese deposit faces serious crisis of resources, and urgently needs mineral prospecting toward the deep subsurface. This manganese deposit is a typical marine sedimentary one in northwestern Guangxi, limited by ore-controlling conditions in lithofacies paleogeography, strata, tectonics and manganese source. Comprehensive analysis of the ore-control factors in the mining area shows that it has good ore-forming geological conditions at depth and in the periphery of the mining area. By analogy with the deep prospecting results of the adjacent Limiao mine area, it can be speculated that there is good prospecting potential in the deep mining area and its periphery, which deserves further ore-prospecting work, and that the ore deposit of this mine area can be expected to achieve a large scale. |
