| 中文摘要: |
| 萤石矿是国家战略性矿产。仁怀市大湾萤石矿床是贵州省新一轮找矿突破战略行动中新发现的矿床。勘查工作和综合分析认为，矿床主要受地层和构造控制。容矿岩石为震旦系灯影组白云岩，寒武系牛蹄塘组对萤石矿的形成起屏蔽作用；北东向的鲁班断层为导矿构造，近南北向的大湾断层为配矿构造，近南北向次级断层、节理，以及牛蹄塘组、灯影组之间的层间破碎带是容矿构造。矿床属低温热液矿床。 |
| 英文摘要: |
| Fluorite ore is a national strategic mineral. The Dawan fluorite deposit in Renhuai city is a newly discovered deposit in the new round of prospecting breakthrough strategic move in Guizhou province. Exploration work and comprehensive analysis suggest that the deposit is mainly controlled by stratigraphy and structure. The host rock is dolomite from the Dengying Formation of the Sinian System, and the Niutitang Formation of the Cambrian System plays a shielding role in the formation of fluorite deposits; The northeast trending Luban Fault is the ore conducting structure, the nearly north-south trending Dawan Fault is the ore matching structure, and the nearly north-south secondary faults, joints, and interlayer fractured zones between the Niutitang Formation and Dengying Formation are the ore hosting structures. The deposit belongs to a low-temperature hydrothermal deposit. |
