英文摘要	Trace elements in fluid inclusions ill vein quartz and sericite-quartzite of Linglong, Jiaojia and Sanshandao gold deposits have been studied by using heating-decrepitation and ICP-MS method. The results show that REE patterns of fluid inclusions appear as LREE-rich type, with better fractionation of lighter and heavy REEs ad LREE/HREE = 6.07 similar to 26.41. However, the fractionation within lighter and heavy REEs is not clear, with (La/Sm)(N) = 2.15 similar to 5.11 and (Gd/Lu)(N) = 0. 72 similar to 5. 24. Ore-forming fluids have weak positive Eu abnormity, with delta Eu = 1.05 similar to 7.09, which is in agreement with acid and hydrothermal solutions of present submarine system. Normalized data of fluid inclusions/element abundance of China Continent Crust show that heavy metal elements, such as Cu, Mo, Pb, Bi, are rich in fluid inclusions, with enrichment coefficient large than 1, while Ti, V, Cr. Co, Li, Zr, Nb, Th and U and depletion elements in fluids. Fluid inclusions in various gold deposits of Jiaojia-Linglong Type have similar REE characteristics, but are differ from gold deposits of other areas. It is indicated again that gold deposits in baodong Peninsula emplaced ill the similar geological settings and were related with hydrothermal solutions in Mesozoic tectonic inversion.
