大屯矿区太原组煤中稀土元素的赋存特征

Distribution characteristics of rare-earth element in coal of Taiyuan Group in Datun Mining Area

运用电感耦合等离子质谱(ICP-MS)和常规的煤岩、煤质分析测试技术,对徐州大屯矿区太原组的腐植煤、腐泥煤、黄铁矿结核、硅质夹矸等样品中稀土元素的分布及赋存特征进行了研究。揭示了煤中稀土元素的含量随着矿物含量、特别是黏土矿物含量的变化而显著变化的特征。

With plasma mass spectroscopmiy （ICP-MS） and conventional coal petrography and coal analysis and measuring technology, the paper studied the distribution and occurrence of the rare-earth element in algal coal, humic coal, pyrites nodule and quartz parting of Taiyuan Group in Datun Mining Area. The study showed that the rare-earth element content in coal would be varied with the mineral contents, specially the clay content.
