| 摘 要： | 采用仪器中子活化分析（INAA）测试了微山湖地区石炭－二叠纪不同沉积环境形成煤样的稀土元素含量，并分析了煤的稀土元素地球化学特征。研究结果表明，煤的稀土元素含量及其配分模式与成煤环境密切相关．具有良好的指相意义。

| Abstract: | The REE in coal samples from different sedimentary environments of the Permo-Carboniferous in the Weishanhu area are analyzed using INAA (Instrumental Neutron Activation Analysis), and the REE geochemistry of coals is dealt with in this paper. The study reveals that the REE contents and REE distribution patterns are closely related with sedimentary environments. The REE geochemistry is a good indicator of the sedimentary environment. |
