| Stable Isotopic Features of the Gold Deposits in the Yiwulunshan Metamorphic Core Complex |

| Abstract:The analytical data of such stable isotopes as hydrogen, lead, silicon, carbon and sulfur in ore-forming fluids from gold deposits in Yiwulushan metamorphic core complex are presented in this paper. The analyses show that the δD values of ore-forming fluids are -97‰～-72‰, whereas δ 18 O values vary from 0.3‰ to 3.8‰, implying varied origins of the ore-forming fluids. Analytical data from other types of isotopic elements indicate that the gold deposits, represented by the Paishanlou gold deposit, have experienced multi-stage ore-forming process characterized by complexity and diversification of material sources. It is therefore held that the Yiwulushan metamorphic core complex system must have played an important controlling role in the formation of gold deposits. |
