摘　　要：在前人研究成果的基础上 ,从化学成分特征这一角度 ,对山东新汶、肥城煤田太原组高岭石粘土岩夹矸进行了主常量元素、微量元素及稀土元素分析。结果不仅进一步证明了 ,研究区高岭石粘土岩夹矸确由火山灰降落于泥炭沼泽或泥炭坪环境后经蚀变而成 ,而且通过对微量及稀土元素分析结果的研究 ,提出该层夹矸的形成可能受到不同期次及不同性质的火山物质影响的新见解 ,为含煤岩系中火山事件沉积的研究提供了新思路。Based on previous study results made by other researchers,this paper works over the tonstein from the chemical composition point of view,by means of main element analysis,trace element analysis and rare earth elements analysis.The result not only makes it further sure that the coal parting of kaolinitic claystone in the study area was formed by the alteration of volcanic ash fallen into the peat moor,also the authors put forward a new idea,according to the results of microelement analysis and REE analsis,that the forming of the coal parting was likely to be influenced by different kinds of volcanic material erupted in not exactly the same period of time,which provides a new way to thinking in the study of volcanic event sediment in coal bearing measures.
