| 中文摘要: |
| 广西佛子冲铅锌多金属矿床是钦杭成矿带西南段著名的代表性矿床之一。文章采用电子探针分析技术,系统分析了广西佛子冲大型铅锌多金属矿床中硫化物矿石的矿物化学特征。研究表明:黄铁矿中S/Fe和Co/Ni元素比值,闪锌矿中Fe、Mn、In 、Ga和Ge等元素含量以及Zn/Fe、Zn/Mn、和Zn/Cd等元素比值,方铅矿中Ag、Ga、Ge、In 等微量元素含量以及Pb/Ag元素比值等具有矿床成因指示意义。矿物化学指标暗示了佛子冲矿床发育与岩浆热液成矿作用具有密切的成因联系,该矿床是一个岩浆热液型铅锌多金属矿床。 |
| 英文摘要: |
| The Fozichong deposit is one of the most famous typical Pb-Zn polymetallic deposit in the southwestern segment of Qinzhou-Hangzhou metallogenic belt. The chemistry characteristics of sulphide minerals in the Fozichong Pb-Zn polymetallic deposit were systemly analyzed by electron microprobe. The result shows that the ratio of S/Fe and Co/Ni in pyrite, the content of Fe, Mn, In, Ga, Ge and ratio of Zn/Fe, Zn/Mn, Zn/Cd, Ga/In in sphalerite, the content of Ag, Ga, Ge, In and ratio of Pb/Ag in galena have recorded the genetic information of ore deposit, and the comprehensive information suggests that the sulphide mineralization was closely related to magma-derived hydrothermal activity, and the Fozichong Pb-Zn polymetallic deposit is a typical magmatic hydrothermal type. |
