Abstract: Jiaodong is the third largest gold deposit concentration area in the world, with gold reserves of more than 5000 tons.The gold deposits are mainly distributed in the Northwest Jiaodong, Qi-Peng-Fu, Mu-Ru and other metallogenic regions.The metallogenic types are mainly fracture zone altered rock-type(Jiaojia-type), quartz vein-type(Linglong-type), and their transition types.Since gold mainly occurs in pyrite and other sulfides, the sulfur isotopic composition of these sulfides can reflect the source of ore-forming materials.In this paper, the sulfur isotopic compositions are classified and statistically compared according to the metallogenic regions, ore bearing depth, metallogenic types and sulfur-containing minerals.The δ³⁴S value of gold deposits ranges from -14.0‰ to 15.1‰, with an average value of 5.5‰ to 13.0‰, and mainly concentrated in 6.0‰~10.0‰.The δ³⁴S value shows the following rules: Mu-Ru metallogenic region > Northeast margin of Jiaolai Basin metallogenic region > Northwest Jiaodong metallogenic region > Qi-Peng-Fu metallogenic region, sulfide quartz vein-type > altered rock-type > quartz vein-type, shallow deposit > deep deposit, pyrite > sphalerite > chalcopyrite > galena.The study shows that the sulfur of the gold deposit is a mixed source, which is composed of multi-source isotopes of Early Precambrian metamorphic rock series, Late Mesozoic granitoids and Mantle material.The change of sulfur isotopic composition is mainly related to the type of country rock and sulfur source.The δ³⁴S value of the gold deposit mixed with much late Mesozoic granite materials is relatively high, but the gold deposit in depth mixed with less crustal materials is relatively low.The sulfur isotope system in the metallogenic process is uniformity and controlled by one centralized explosion metallogenic event.
