摘要：
Studies on rocks and ores of Jianchaling ore deposit, southern Shaanxi, show that REE patterns in the ores clearly differ from that in ultrabasic and acidic rocks. The REE pattern in Ni ore is similar to that in Au ore and is characterized by typical enrichment in LREE and sharp negative Eu and Ce anomalies, indicating that Ni ore and Au ore were formed from the same hydrothermal solution. δ Eu and δ Ce variations reflect that Ni ore is formed at higher temperature and relative reduction environment, and Au ore at lower temperature and relative oxidation environment. The characteristics imply that the ore forming materials were derived from the ultrabasic rock and the hydrothermal solution is a post magmatic acidic solution.
