| 摘 要： | 对金顸铅锌矿床和白秧坪Cu-Co-Ag矿床成矿阶段形成的热液矿物中原生流体包裹体的He，Ar同位素研究结果表明：金顸铅锌矿床的成矿流体的。He／^4He值为0．19～1．02Ra，^40Ar／^36Ar值为274～305，白秧坪Cu-Co-Ag矿床0．71～4．60Ra，^40Ar／^36Ar值为290～334，表明成矿流体中可能含有地幔He。这些新资料的获得为研究该区成矿作用和深部的关系提供了同位素地球化学依据。

| Abstract: | The paper presents new helium isotope data from fluid inclusions of hydrothermal minerals of the main mineralization stage.The ~3He/~4He ratios are 0.19 Ra~4.6 Ra and the ~(40)Ar/~(36)Ar ratios are 274~334,which indicates a mantle component of hydrothermal fluids. It is suggested that the ore-forming fluids were part of mantle-derived fluid and involved in metallogenic contribution of deep processes. |
