///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 chondrite-normalized 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.
