Special appearance of REE geochemistry of soluble hydrocarbon in coal--An example of a middle rank coal from Weibei
煤可溶烃中一种特殊的稀土元素地球化学现象 ——以渭北中熟煤为例

The REE distribution between soluble hydrocarbons and minerals in a middle rank coal from Weibei,Shaanxi province,China,was studied with statistics method.It was found that there is a clear complementary relationship of REE between the soluble hydrocarbons and minerals.Among them,LREE and HREE have different distribution characters respectively,which are determined by the change of ions radii and inner electronic configuration.For this reason,the bigger atomic number of LREE,the less regularity of LREE dist...
