| 摘 要： | 海沟金矿是大型石英贫硫化物脉型金矿床。矿区侵入岩可划分为四个花岗岩单元，矿体（脉）在平、剖面上都具有斜列的特点。含金石英脉的产出和分布严格受ＮＮＥ－ＮＥ向断裂控制。金矿区控矿构造型式为ＥＷ向大断裂的派生断裂控制矿床，成矿构造序列划分为成矿前、成矿期、成矿后构造。构造对矿床（矿体）的控制作用主要表现为等距性构造控制矿脉分布；断裂多期活动对富矿体的控制。分析了断裂构造地球化学特征，表明成矿作用是以充填

| Abstract: | The Haigou gold deposit belongs to a large,poor sulfide,quartz vein type.The intrusive rocks can be divided four granite units,showing oblique orientation of spread on the plane and section of the orebody (vein).The occurrence and distribution of auriferous quartz is strictly controlled by NNE-NE fault.The ore deposit is controlled by the fractures induced from EW large faults in this area.From metallotectonics,they belong to premetallogenic,mineralization and postmetallogenic struture.The structures show equidistant ore-control distribution and rich-ore control by the multiperiodic activities of the faults.In this paper,by the analysis of geochemical characteristics of faulted structure,it is showed that the filling is dominant in ore-forming process. |
