    Major ions were analyzed in the Department ofGeology,Renlou Coal Mine.REE concentrations of groundwater were determined after pre-concentration by
    liquid-liquid extraction,and analyzed by inductively coupled plasma mass spectrometry in the State Key Laboratory of Geological Processes and
    Mineral Resources,China University of Geosciences(wuhan).Analytical process followed the method reported by SHABANI et al .The isobaric interference of BaO to Eu had not been well corrected,leading to the useless Eu among these REEs .The analytical precision for all REEs except for Eu was 10% or better.REEs of rocks
    were analyzed with PE Elan 6000 ICP-MS at the Key Laboratory of Isotope Geochronology and Geochemistry,CAS.The relative derivations were less than 5%,and detailed analytical procedures were referred to LIU et al.
