摘要
云南省铝土矿资源勘查和开发利用程度低,相关地质研究也很薄弱,铝厂原料供应主要由国外或省外进口,随着文山80万t氧化铝厂的建成,云南省十分迫切需要铝土矿资源,因此,加强省内铝土矿勘查和研究具有十分重要的实用价值和理论意义。目前,云南省已发现的铝土矿床主要分布于滇东南、滇西和滇中地区,铝土矿成矿期分别为二叠纪晚期、三叠纪晚期和二叠纪早期。本文在勘查实践和地质科研的基础上,总结了云南省铝土矿矿床类型及成矿规律,为铝土矿后续勘查和开发提供依据。
Raw material of aluminum plant in Yunnan Province is counted on completely imports from other provinces or foreign countries. Bauxite has a low degree of exploration and development. While the aluminum oxide factory of the annually production is 800000 tons built in the Wenshan County is badly in need of bauxite raw material. Therefore there are important practical value and theoretical significance to strengthening study on bauxite exploration in Wenshan County. Bauxite deposits have been found mainly in the southeastern, western and central Yunnan Province. They were formed at the end of the Permian and the Triassic, and the Early Permian period. The deposit types and ore-forming regularities of bauxite are summed up by exploration practice and geological research in the paper. It is the basis for follow-up exploration and development in Yunnan Province.
