| 摘 要： | 三道湾子金矿是与大兴安岭燕山期火山活动有关的浅成中-低温热液金矿,矿石类型主要为石英脉型.矿石的结构为自形-半自形-它形粒状结构、碎裂结构、交代结构、包含结构.矿石的构造为致密块状构造、稀疏浸染状构造、角砾状构造、细脉状构造.矿体浅部金矿物以自然金、银金矿为主,呈裂隙金、粒间金、包裹金分布,金矿物以细粒为主,载金矿物主要为石英;深部富矿段金、银主要以碲化物形式存在,赋存于石英颗粒间或裂隙中.反映了成矿流体的阶段性及层次性. |
| 关 键 词： | 三道湾子 石英脉型金矿 碲金矿 赋存状态 |

| Abstract: | The Sandaowanzi gold deposit is a mesothermal-epithermal volcanogenic gold deposit which located in the DaHinggan Mountain metallogenic belt of Yanshanian epoch.Mineralization is mostly hosted within quartz veins.The ore textures include automorphic-hypautomorphic-xenomorphic granular,cataclastic,metasomatic and poikilitic.The ore structures mainly show massive,disseminate,brecciated and veinlet.At shallow depth the gold occurs as fine grained native gold and electrum,and distributes in fissures,intergranul... |
| Keywords: | gold deposit quartz vein type gold occurrence state Sandaowanzi |
