摘要
鸡冠嘴铜金矿床位于断陷盆地边缘,其构造较为复杂,其基础构造是北西西—近东西向褶皱断裂系统,同时又发育有滑覆构造,成矿期叠加有北北东向的构造。滑覆构造与北北东向构造联合共同控制着矿床中矿体的分布,形成四个构造矿化分区。矿体主要赋存在叠加背斜的核部、滑覆背斜的核部、北北东向断裂两侧的羽状裂隙中。根据构造控矿规律,矿床具有极大找矿前景,主要找矿有利地段是滑覆构造下伏岩系中控制的矿体以及被后期断裂错失的控矿构造系统中。
Jiguanzui copper-gold deposit is located in the margin of graden basin,and its structure is more complicated.The basic structure is WNW-nearly E W trending fold fracture system,while there is gliding nappe development.Superimposed mineralization is the structure of NNE.Ore bodies are found in the core of superimposed anticline,the core of the gliding nappe anticline and NNE-trending fault on both sides of the feather fracture.According to structural ore-controlling law,ore deposit has great prospects.Favorable areas for prospecting are mainly ore bodies controlled by the underlying rock series and ore-controlling tectonic system missed by late fracture.
