低熟煤中的孢粉与常量元素和微量元素的相关性初探

运用电离耦合等离子体原子发射光谱(ICP-AES)和X射线荧光光谱分析(XRF),对新疆八道湾煤矿中侏罗统西山窑组煤中的孢粉角质层进行了分析,测定了煤中的常量和微量元素。并对煤中孢粉和共伴生元素进行了回归分析,探讨了微量和常量元素的煤岩学及孢粉学属性,在微量元素与孢粉的煤相学应用方面作了初步尝试。结果表明,成煤的蕨类植物孢子和裸子植物花粉与某些常量元素和微量元素有着很高的相关性;蕨类植物孢子和裸子植物花粉的相对含量在煤中具有互补性,决定了它们与微量元素的关系也具有一定的互补性。 

Relationship between sporopollen and major/ trace elements in the low-rank coals

The content of major and trace elements and the sporopollen cutin in the coals of the Middle Jurassic Xishanyao Formaiton of Badaowan coal mine, Xinjiang, were analyzed using ICP-AES and XRF. The petrologic and sporopollen properties were discussed according to the regressive analysis between sporopollen and associated elements in coal. In addition, applications of trace elements and sporopollen to coal facies were preliminary discussed. The results show that there is a strong positive correlation between pteridophyt,a spore/gynnosperm pollen and some major/trace elements in coal. The results also indicate that the complementary of the content between pteridophyta spore and gymnosperm pollen dominates the correlation between spore/pollen and trace elements.
