| 中文摘要: |
| 通过对贵州威宁玉龙铌矿化体的成矿地质背景、矿区地质特征的叙述及对矿化成因进行探讨，提出了区域上铌矿找矿方向：区域上陆相沉积的二叠系上统宣威组（P3x）在特定的地质、地球化学环境下可能局部富集形成可供开发的铌矿体；与二叠系上统宣威组（P3x）具有相同物源的陆源碎屑沉积二叠系上统龙潭组（P3l）含煤岩系，在特定的地质、地球化学障背景下铌是否富集成矿值得进一步研究。 |
| 英文摘要: |
| By narrate the mineral geologic background and geologic features and discuss the mineralization genesis of niobium mineralization body in Weining, the prospecting direction of niobium in this area is carried out. In this area, upper Permian Xuanwei formation of land facies sediment concentrated and formed developable niobium body in special geological and geochemical environment. In the coal-bearing rock series of upper Permian Longtan formation which has the same land source with upper Permian Xuanwei formation, whether niobium concentrate in special geologic and geochemical environment is worth to study. |
