摘　　要：采用电感耦合等离子体质谱(ICP-MS)对贵州西南煤区四个区域8个煤样的稀土元素含量进行了测试,对稀土元素的地球化学参数、稀土元素的分布模式、稀土元素的赋存及来源进行了探讨,发现西南煤区的稀土元素含量略低于中国煤中稀土元素的总量均值;煤样之间的稀土元素分布模式十分相似,呈左高右低的宽缓的"V"型曲线(球粒陨石标准化图),西南煤区稀土元素的物质来源主要受陆源物质的影响和控制。The contents of rare earth elements （REE） of 8 coal samples in southwestern Guizhou province were determined by ICP-MS and their geochemical parameters,occurrence and distribution pattern were discussed in this paper.The results show that the contents of REE in southwestern Guizhou province in average is closed to the Chinese coals;Distribution patterns of the rare earth element in coal are similar and the chondrite-normalized diagram of coal shows a V-shaped curve inclining towards the right,it is believed that substance origin of the rare earth elements is under the control of terrigenous impaction therefore.
