| 摘 要： | 豫西熊耳山变质核杂岩中的祁雨沟金矿,为一爆破角砾岩型金矿床。其中J4号角砾岩体为矿区内众多含矿角砾岩体之一,其矿化类型有两类:一是脉状矿化,形成脉状金矿体;另一类为胶结物矿化,形成不规则状金矿体。金矿化具有水平方向上的不均匀性和垂直方向上的分带性。在水平方向上,矿化多集中分布于爆破角砾岩体的西北部,其它部位矿化较弱。在垂向上,脉状矿化主要分布于爆破角砾岩体490 m以上,受剪切裂隙带控制;胶结物矿化,主要分布于490 m以下,矿体的空间产出受角砾岩体的形态控制。 |

| Abstract: | Qiyugou gold deposit which is located in Xiong＇er Mountain metamorphic complex of western Henan province is a typical explosion breccia-type gold deposit,no.J4 breccia is a typical ore-body of this deposit.Two types of mineralization are found in no.J4 breccia,one is the vein-type,the other is cement-type.The spatial character of ore minerals is that heterogeneity in the horizontal direction and zonation in the vertical direction.In horizontal direction,the most ore minerals concentrated in northwest of no.J4 breccia,while little located in other parts of this breccia.In vertical direction,two types of mineralization distributed in different parts,the vain-type is mainly above 490 m level,controlled by the shear fracture zone,but the cement-type is mainly distributed under 490 m,controlled by the shape of breccia. |
