There is a close space-time relation between Mesozoic Yanshanian intrusive rocks and gold deposits in the Wulong area, eastern Liaoning province. This kind of intrusive rocks have similar ratios of trace elements (Th/ U, Zr/Hf, Nb/Ta). The ratios of (87Sr/86Sr)i and (143Nd/144Nd)i keep unchanged despite of the change of the SiO2 and MgO contents in different rocks, which shows that the magma was not obviously contaminated in the emplacement process, and that different rocks have the same magma source. Compositions of Sr and Nd isotopes show that diagenetic materials mainly came from the lower crust. The similar Pb isotopic compositions of the Sanguliu granite and ores in addition to the fact that the Au-bearing quartz veins cut through the Sanguliu granite body indicate that the Sanguliu granite is not a direct supply of metallogenic materials, It is considered that the diagenetic and metallogenic materials mainly came from the same deep sources, and that the gold deposits are products of magmatic evolution of the same provenance but different stages.
