ZHU Jun-bin1,2,FANG Wei-xuan1,2,LIU Jia-jun1,HU Yu-zhao2,3 (1.China University of Geosciences,Beijing 100083,China;2.Beijing Resources Exploration Technical Center of China Non-ferrous Metals Resource Geological Survey,Beijing 100012,China;3.Kunming University of Science and Technology,Kunming 650093,China)  
An investigation on the REE geochemistry of the ore-bearing strata and surrounding rock of Qinglong antimony deposit show that the ΣREE changes greatly while REE patterns is stable,characterized by the obviously negative Ce anomaly,positive Eu anomaly and flat REE distribution pattern.Comparison with the basalt's REE distribution patterns illustrate that there is significant difference between them.Microscopic characteristics of the surrounding rocks,ore structure and field observations indicate that the ore materials had been transferred through NE fault,such as Huayujing and Leibodong faults,and then deposited in "Dachang Layer" as a result of the change of the redox and P,T conditions.
