摘要
对《煤的稀土元素地球化学》一文某些问题的讨论，认为：煤与煤灰是两个不同的概念，不能用煤灰的稀土元素丰度来讨论煤的稀土元素丰度；煤的灰分增高，稀土元素含量也增高，表明煤中稀土元素主要来源于陆源碎屑的供给。
Some viewpoints of“Geochemistry of Rare-Earth Elements in Coals”are discussed in this paper.The view points of this paper are:1>Coal differs from coal ash in concept.And the contents of REE in coal are not equal to the ones in coal ash.2>The more the coal ash,the higher the contents of REE in coal.And this reveals that the main supply of REE is terrigenous clastics.
