| 中文摘要: |
| 来凤县凤坡岭重晶石 -萤石矿床位于上扬子陆块南部被动边缘褶冲带，恩施 —黔江台褶束南西段，重晶石与萤石矿脉产于奥陶纪地层中，由红花园组的岩层孕育而成，这些矿脉的产出，严格遵循着区内的断裂和 裂缝构造，其形态与这些构造的走向相吻合。矿脉填充在断层带破裂的地方，而丰富的重晶石和萤石则 主要集中在断裂带的上层部分，深部为碳酸岩化、重晶石 -萤石化角砾灰岩。矿床成因类型属中低温热液 |
| 英文摘要: |
| The Fengpoling barite fluorite deposit in Laifeng is located in the southern passive margin foldthrust zone of the Upper Yangtze Block and in the southwestern section of the Enshi -Qianjiang Plateau fold bundle.The barite fluorite veins occur in the Honghuayuan Formation of the Lower Ordovician，and their production iscontrolled by internal faults and fracture structures. The occurrence of the veins is consistent with that of the faultsand fracture structures. Barite fluorite veins are filled in fault fractured zones. Barite fluorite is enriched in the shal. low part of the fractured zone，while the deep part is carbonate rock and barite fluorite breccia limestone. The genetic type of the deposit belongs to the medium low temperature hydrothermal vein type deposit. |
