Abstract: The REE data of ores, altered rocks and related rocks, and minerals in gold and copper deposits in Shizishan ore-field of Tongling region are collected to compare and discuss the differences of REE geochemical characteristics between gold deposits and copper deposits. The magmatic rocks, ores and related altered rocks in gold and copper deposits have similar chondritenormalized REE patterns, LREE/HREE and (La/Yb)N values, which displays that the ore-forming elements mainly come from the magmatic rocks, and are rich in crust materials. The deep ore-forming hydrothermal fluids may gain REE and ore-forming elements by leaching the crystallized magmatic rocks, and then superimpose and reform the sedimentary rocks. The mineralization is closely associated with magmatism. The REE geochemical characteristics in different stages and in different kinds of ores and altered rocks imply that the origin and evolution of REEs is closely related with that of ore-forming elements. On the other hand,REE geochemical characteristics of ores in gold and copper deposits also have significant differences. The REE contents in ores are lower in skarn stage than in quartz-sulfide stage. The REE distribution patterns of some skarns and skarn ores are LREE enriched, but with La and Ce depletion, which indicates a magmatic origin of these skarns and skarn ores in copper deposits;while the skarns in gold deposits and the other skarns in copper deposits were formed by metasomatism. The δEu values of the ores indicate that the ore-forming hydrothermal fluids had different pressures and different evolutionary features in different mineralization stages.
