| 摘 要： | 偃龙煤田深部铝土矿矿床是豫西典型的隐伏铝土矿床,赋存于中奥陶统侵蚀面之上的石炭系本溪组中.含矿岩系的厚度及矿体形态受古岩溶面控制,构造对矿体影响较大.矿石主要矿物成分为一水硬铝石、高岭石、伊利石等含铝矿物.上部铝质泥岩以高岭石为主,下部铝质泥岩以伊利石为主.铝土矿共生矿产综合开发价值大,伴生矿产有待进一步研究.

| Abstract: | The Yanlong bauxite deposit, which occurs in Carboniferous Benxi Formation on the Middle Ordovician erosion surface, is a typical concealed bauxite deposit in western Henan Province. The thickness of ore-bearing formation and shapes of bodies are controlled by the paleo-karst erosional surface, and are greatly influenced by structures. The dominant Al-bearing minerals include diaspore, kaolinite and illite. The upper and lower parts of the bauxitic mudstone are mainly based on kaolinite and illite respectively. The paragenetic minerals of bauxite have a great value, while the associated minerals need further study. |
