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 pteridophyta spore/gymnosperm 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.
