     In order to investigate the abundance and distribution pattern of rare earth elements （REE） in coals at Western Huagou exploration area when coal seams were intruded by magma, ICP-MS, XRF were used to analyze in 24 coal samples and 8 magmatic rock samples. The REE＇s data in the No.8 and No. 10 coal-beds were compared in order to find the features of REE in coals which altered. Main conclusions are as following： （1） The average content of REE in coals at Western Huagou exploration area is 92.09 ×10^-6. The value of LRRR/HREE is between 6.54 and 8.53. （2） The abundance of REE in coals was changed caused by the igneous invasion, and the intrusion lead to a second migration and enrichment of the REE. And this process will be influenced by the components of magma.
