摘要
采用X射线荧光光谱(XRF)和电感耦合等离子体质谱(ICP-MS)等方法分析了淮北煤田煤中主量元素和微量元素特征,并根据元素特征探讨了研究区煤中微量元素的环境意义。研究发现主量元素以Si和Al为主,两者之和达20%。从底部煤层到上部煤层,整体上经历了低位泥炭到高位泥炭的过程。Sr/Ba、V/(Ni+V)和Sr/Cu等微量元素比值指示淮北煤田形成于半咸水-海相,厌氧、干热的沉积环境。
The characteristics of major elements,trace element were analysed by the method of XRFand ICPMS. According to these elements characteristics, the environmental significances were discussed. The results indicated that Si and Al were the main major elements, and the sum of the two elements was up to 20 %. From the bottom of the coal mine to the top,they underwent the process of lowland bog to the high bog. The ration of Sr/ Ba,V/（Ni＋V）,Sr/Cu indicated that huaibei coalfield formed from the environment of Marine, anaerobic and xerothermic.
