| 摘 要： | 本文通过对铜厂铜矿的Ｓ，Ｈ，Ｏ和Ｃ同位素地球化学研究，认为本矿床属于与闪长岩有关的中低温硫化物矿床，在成矿阶段的实始热液为岩浆水，含矿流体是一种岩屑水与天水混合而Ｋ＾＋混合流体，矿床中Ｓ主要来源于细碧岩，部分来源于闪长岩，推测成矿物质来源物质也来源于细碧岩。

| Abstract: | Research on the isotopic geochemistry of S, H, O and C for Tongchang copper deposit reveals that the initial hydrothermal solution came from the magmatic water and the ore-forming solution was a kind of K + rich mixture of magmatic water and atmospheric water. The sulfur in the ore was mainly originated from spilite and part of it came from diorite. The intrusion of the Hercgnian period diorite brought about the alteration of spilite and heary S and activated Cu in spilite entered hydothermal solution which migrated to the inner and outer contact zone of diorite, where they precipitated to form sulfide. Therefore, the Tongchang copper deposit is characterized by the enrichment of herary sulfur. |
