为了研究373矿床成矿流体特征，分别测定了矿脉中方解石微量元素含量和碳氧同位素地球化学组成。结果表明，373矿床方解石轻稀土富集，轻重稀土显著分异，配分模式以右倾为特征，相对富集Sb、 Mo、 Co、 Ni，δ13 CPDB范围为2.78‰～0.68‰，δ18 OSMOW的范围为17.52‰～19.76‰。结合图解综合分析得出结论，373矿床的成矿流体应为多源的混合流体，早期封存在地层中古海水、深层水与淋滤而下的大气降水和地下水形成热液环流，同时可能受深源流体的影响。

To study the fluid characteristics of 373 deposit, trace elements and carbon and oxygen isotope of calcite in veins were measured .The results showed that calcite in 373 deposit is characterized with enrichment of LREE , significant differentiation of LREE and HREE , right deviation of REE distribution pattern.Calcite is relatively riched in Sb, Mo, Co,δ13CPDB is 2.78 ‰~0.68 ‰;δ18OSMOW is 17.52‰~19.76‰.Combined with diagrams , it is can be concluded that ore -forming fluid of 373 deposit is the hydrothermal circulation of paleoseawater that sealed in the formation early , deep water , precipitation and groundwater as well as the participation of deep fluid .
