| 摘 要： | 河南嵩县祁雨沟金矿区四号角砾岩筒是燕山晚期中酸性岩浆超浅成侵位而形成的隐爆-坍塌型角砾岩筒,第一期矿化形成受角砾岩筒形态制约的不规则状胶结物型金矿体,第二期矿化形成受断裂裂隙制约的脉状矿体。前者主要受角砾岩筒本身的形态制约,形成不规则状矿体;后者受制于剪切裂隙系统,形成含金石英-多金属硫化物脉状金矿体。两种不同的矿化类型在垂向上存在明显分带性。在490m中段以下主要为受角砾岩筒形态控制的不规则状胶结物型金矿体,490m中段以上则逐渐过渡为受叠加裂隙控制的脉状矿体。

| Abstract: | The No.4 breccia pipe in Qiyugou Au mining area of Song county of Henan is cryptoexplosive-slump brec- cia pipe formed by super-hypabyssal emplacement of late Yanshanian intermediate acidity magma.The first phase of mineralization formed tuberose cementing material Au ore body limited by shape of breccia pipe;the second phase of mineralization formed veined ore body limited by faulted fracture.The former is mainly controlled by the shape of breccia pipe and forms tuberose ore body;the latter is controlled by shearing fracture system and forms veined ore body which contains Au-quartz-polymetallic sulfide.These two different kinds of mineralization have obvious zonality in the vertical direction.Below middle section of 490 mthere is mainly tuberose cementing material Au ore body which is controlled by shape of breccia pipe,and above middle section of 490 mit gradually becomes veined ore body which is controlled by superposition fracture. |
