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.
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-beating 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 are mainly based on kaolinite and illite respectively. The paragenetic minerals associated minerals need further study. and lower parts of the bauxitic mudstone of bauxite have a great value, while theassociated minerals need further study.
