中文摘要：

利用电感耦合等离子原子发射光谱和电感耦合等离子质谱仪对准东煤田不同勘探区煤样中常量和微量元素含量进行测定,对准东煤田主要勘探区煤地球化学特征与中国和世界范围煤地球化学特征进行较系统对比。划分煤中微量元素组合特征,归纳各区内煤的常量与微量元素亲和性。较系统地揭示了准东煤田煤中微量元素丰度和赋存状态,对煤田大规模资源开发利用地球化学环境条件及煤中伴生元素工业利用提供参考。

英文摘要：

The concentrations of the major and trace elements in the coals from different exploration areas of the Eastern Junggar coalfield were determined by the inductively coupled plasma-atomic emission spectrometry and the inductively coupled plasma-mass spectrometry.The results shows that the Al,K and Fe contents in the Eastern Junggar coals are obviously lower than the average values reported for Chinese coals,whereas the Na content is higher than the average of Chinese coals.Furthermore,the Al,K and Fe contents in the coals from the eastern prospect areas are higher than that from the western areas.With the exception of Sr and Ba,the concentrations of other trace elements in the Eastern Junggar coals are all low compared to the average values reported for the Chinese and worldwide coals.
