首次填出白云鄂博矿区周围火成碳酸岩岩墙的分布图，深入系统地研究了岩墙的地质产状、主矿物类型、岩石结构、人工重砂矿物组成、稀土元素含量等特征。反映了白云鄂博矿区周围火成碳酸岩岩墙的岩浆演化分异过程存在差异。对于研究白云鄂博矿区铁与稀土的矿化提供了物质来源的证据。 For the first time, the distribution map of volcanic carbonatite dykes around the Bayan Obo mining area was developed. The geological occurrence, main mineral types, rock structure, artificial heavy mineral composition and REE contents of the dyke were systematically and systematically studied. This shows that there are differences in the magmatic evolution differentiation of volcanic carbonate rock dikes around the Bayan Oubeo mining area. It provides evidence of the material source for studying the mineralization of iron and rare earth in the Bayan Obo mine area.
