| 摘 要： | 石坞金矿位于钦杭成矿带东段之金山金矿田的北缘,是目前矿田内发现的第二大矿床。通过开展矿床地球化学特征研究表明,其主量元素SiO2为带入组分,Al2O3、TiO2、MgO、Na2O、K2O、P2O5为带出组分;微量元素显示出富集高场强元素Th、U、La、Ce、Zr、Hf,亏损大离子亲石元素Sr、Ba等特点;稀土元素球粒陨石标准化配分曲线均呈右倾型,轻重稀土分馏明显,富集轻稀土元素,具有明显的Eu负异常。上述特征揭示了石坞金矿的成矿物质均来源于新元古界张村岩组,形成于岛弧拉张背景下,这一认识对探讨石坞金矿的成因具有重要的意义。

| Abstract: | Shiwu gold deposit is located in northern part of the famous Jinshan gold field and the second largest deposit of the field. The characteristics of the rocks from shiwu gold deposit showed that SiO2 is the brough in component, Al2O3, TiO2, MgO, Na2O, K2O, and P2O5 are the carried out components, and the trace elements are rich in HFSE such as Th, U, La, Ce, Zr, and Hf, depletion of LILE such as Sr and Ba; and the rare earth elements of the rocks are characterized by LREE and HREE significant fraction and rich in LREE and significant depletion of Eu. The geochemical characteristics indicate the metallogenic material of Shiwu gold deposit are originated form Zhangcun formation and the rocks are formed in island arc geologial setting. This conclusion can provide a very important significance for the genesis of Shiwu gold deposit. |
