摘　　要：利用综合地质研究手段,通过地表地质调查、地质统计学、元素空间富集规律、最新深部钻孔资料及流体包裹体的研究,提出了白云鄂博铁、稀土、铌矿床成因认识,认为白云鄂博铁、稀土、铌矿是火成碳酸岩浆成因,伴随后期多期热液交代活动。该成果为白云鄂博建立找矿模式、进行成矿预测及评价、准确寻找资源靶区提供了重要依据。In this paper,the cognition for ore genesis of iron,rare earth and niobium of Bayan Obo is put forward with comprehensive geological research means through surface geological survey,geostatistics,element spatial concentration regularity as well as researches of the latest deep drilling data and fluid inclusions.It is considered that the iron,rare earth and niobium ores are the genesis of igneous carbonate magma accompanied by multi-period hydrothermal metasomatism in later period,which provide important basis for Bayan Obo to establish the prospecting model,conduct metallogenic prediction and evaluation as well as accurately search for resource target regions.
