| 中文摘要: |
| 本文依托中国矿产地质志项目，对贵州西南部萤石矿成矿规律进行了分析总结，认为区内萤石矿均为燕山期浅成中低温热液型矿床。该类型萤石矿床具有“在容矿岩层(碳酸盐岩、玄武岩、硅化蚀变岩)之上覆盖有渗透性差的屏蔽层(泥质岩石、少数为火山凝灰岩等)的特点；区内沉积地层具有四套上述赋矿岩性组合，分别为:石炭系至二叠系间断面底界、二叠系中统至上统底界、二叠系上统至三叠系下统底界及三叠系中统碳酸盐岩。本文对目前成矿地质条件好、勘查控制程度高的三类萤石矿赋矿组合分别建立了矿床式，在此基础上对各矿床式的深边部及外围找矿前景进行分析，进而划分出四个找矿远景区，为今后找矿及研究提供参考。 |
| 英文摘要: |
| On the basis of the ‘Geology of Mineral Resources of China’,the metallogenic regularity of fluorite deposits in southwestern Guizhou is analyzed and summarized in this paperThis type of fluorite deposit has the characteristics of ‘Shielding layer with poor permeability (mudstone,volcanic tuff,etc.) overlying host rock (carbonate rock,basalt,silicified altered rock)’. The sedimentary strata in the area have four sets of ore-bearing lithologic assemblages,they are Carboniferous to Permian discontinuity bottom boundary: Permian middle to upper boundary,Permian upper to lower Triassic bottom boundary and Triassic middle carbonate rocks. In this paper,three types of fluorite ore-bearing assemblages with good metallogenic geological conditions and high degree of exploration and control have been established respectively,and then divided into four prospective areas and provide a reference for future prospecting and research. |
