| 摘 要： | 采用原煤直接溶样和使用ＩＣＰ－ＭＳ方法对我国平朔，大同，六盘水和唐山几个主要煤产地煤的微是元素进行了检测，报道了这几个主要煤产地煤中５１种微量元素含量，并对基含量特征进行了讨论，研究表明，与海水有关的过渡相沉积环境中的煤的Ｌｉ，Ｂｅ，Ｓｃ，Ｔｉ，Ｖ，Ｚｎ，Ｃｕ，Ｇａ，Ａｓ，Ｓｅ，Ｙ，Ｚｒ，Ｓｎ，Ｐｂ，Ｔｈ，Ｕ和稀土元素含量相对较高，内陆湖泊沉积环境中的煤的微量元素含量相对较低。

| Abstract: | The trace elements in coals from several main coal districts in China were analyzed by means of ICP-MS,with direct dissolution of coal samples in this study. 51 trace elements in these coals are systemat-ically reported,and their concentrations are discussed. In transitional phase sediment environments related with marine coals have relatively high content of Li, Be, Sc, Ti, V, Zn, Cu, Ga, As, Se, Y, Zr, Sn, Pb, Th, U and REE. In continental sediment environments,relatively low content of the trace elements. |
