| 中文摘要: |
| 文章对石盘沟金矿区产出的J41、J12号角砾岩体和祁雨沟金矿床典型含矿角砾岩体J5黄铁矿标型特征及其含矿性进行了探讨,并进行了详细的对比,研究表明,岩体的角砾形态、大小与含矿性没有直接的关系,角砾的含量与含矿性成反比；富矿黄铁矿一般呈他形粒状或碎裂状,粒度较细,颜色多呈浅铜黄色；角砾岩体富矿部位的温度较高,有明显的主爆峰。据此提出J41号角砾岩体的中心有较好的矿化前景,而J12号矿化前景较差。 |
| 英文摘要: |
| The paper discussed No.J41 and No.J12 breccia, typomorphic characteristics of the pyrite from typical ore-bearing breccia pipe No.J5 and its mineralization in Shipangou gold deposit. The result indicated that no direct relationship between the shape, size of breccia and gold mineralization, but the content of breccia decreased with the mineralization intensity. The pyrite mineral from high grade gold ore is usually allotriomorphic granular or cataclastic and fine grained with light brass color. The temperature is higher in the high grade of breccia pipe showed that the eruption reached peak value. It was proposed that there is prospecting potential for gold orebody in the central part of breccia pipe No. J41 but less potential within No. J12 breccia pipe. |
