摘要
湖南西部花垣铅锌矿床，是近年来发现的产于下寒武统清虚洞组上部藻礁灰岩中的大型ＭＶＴ矿床。矿床的矿石矿物中普遍有流体包裹体存在，其中有子矿物发现。采用ＳＥＭ和ＥＤＸ对它们进行研究后，在４种主矿物中发现有７种子矿物：闪锌矿、石膏、方解石、重晶石、石盐、黄铁矿和沥青。硫酸盐类矿物在包体中的发现，证明成矿流体中，ＳＯ２－４的含量较高，而且可能是与金属离子共同迁移。
The Huayuan lead zinc deposit is a large MVT ore deposit in Hunan Province, southern China, which occurs in the algal reef limestone of Lower Cambrian. Fluid inclusions are very common in this ore mineral, and seven daughter minerals have been found in it throngh the use of SEM and EDX, that is, sphalerite, pyrite, gypsum, barite, calcite, halite and bitumen. The presence of sulphate minerals shows that the concentration of SO 2- 4 is relatively high, and it may be migrated with metallic ion in mineralizing fluid.
