【摘要】 经过细致的野外工作和室内分析将金英金矿床构造划分为北东、北西、东西、北北东、南北等5个构造带及华夏系、北西向构造带、东西向构造带、新华夏系、南北向构造带等5个构造体系,提出了华夏系→北西向构造带→东西向构造带→新华夏系→南北向构造带的构造演化史。研究表明,区域上以华夏系构造为主,金英金矿床金矿化处于北西向构造带中并沿北东向构造分布,即北西向构造与北东向构造交汇部位是成矿的有利部位。更多还原

【Abstract】 The structures of Jinying gold mine are divided into five tectonic zones by detailed field work and indoor analysis,i.e.,NE,NW,EW,NNE,SN.These structures belong to five different tectonic systems:Cathaysian system,NW tectonic zone,EW tectonic zone,Neocathaysian tectonic system,SN tectonic zone,whose tectonic evolutionary track is as following:Cathaysian→NW tectonic zone→EW tectonic zone→Neocathaysian→SN tectonic zone.The study indicates that the Cathaysian system is the major structures in the study area,and gold mineralization lies in the NW tectonic zone which distributes along the NE tectonic.In other word,the mineralization occurs in the intersection zone of NW and NE tectonic.更多还原
