矿床是地壳演化过程中的产物。世界著名的白云鄂博铁—铌—稀土多元素综合矿床,就是阴山大地构造演化过程中蕴育的一颗“明珠”。本文运用大地构造学家陈国达教授所创立的地洼学说观点,作为研究、分析这个地区大地构造演化史的理论根据,从而揭示了其与白云鄂博铁矿床生成的内在联系,解释矿床成因类型,划分出了成矿阶段。 文章首先从研究区内地层沉积顺序、岩浆活动规律、构造旋迥入手,认为本区存在初 The deposit is the product of the evolution of the crust. The world-famous Bayan Obo iron-niobium-rare earth multi-element deposit is a “pearl” in the Yinshan tectonic evolution. In this paper, the tectonic theory of Diwa, founded by Professor Chen Guoda, is used as a theoretical basis for studying and analyzing the tectonic evolution of the tectonic setting in this area, revealing the intrinsic relationship between the tectonic evolution and the formation of the Baiyunebo iron ore deposit, explaining the genesis of the deposit, Divided into the stage of mineralization. First of all, from the study of the sequence of sedimentary stratigraphy in the area, the law of magmatism and the structure rotation, we conclude that there are early
