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 content of rare earth elements in eight coal samples from four areas in southwestern Guizhou coal seam was tested by inductively coupled plasma mass spectrometry (ICP-MS). The geochemical parameters of REE, REE distribution pattern, REE occurrence The results show that the content of rare earth elements in the southwest coal area is slightly lower than the average amount of rare earth elements in coal in China. The pattern of rare earth elements distribution between coal samples is very similar, V "curve (chondrite normalized map), the source of rare earth elements in the southwest coal area is mainly affected by terrestrial sources and controlled.
