| 摘 要： | 黑龙江省东北部嘉荫—萝北成矿带是重要的金矿成矿带,勘查区内金矿床属于破碎带蚀变岩石英脉型金矿即金主要富集在石英脉中。我们对金矿成因进行研究,认为成矿流体沿构造裂隙向上运移并在运移过程中萃取围岩中的成矿物质,在区域变质作用一褶皱作用之后形成的控矿断裂构造为含矿溶液提供了沉淀空间,最终形成金矿体。

| Abstract: | Jiayin—Luobei metallogenic belt in northeastern Heilongjiang Province is an important gold metallogenic belt,the gold ore in our belongs to crushed zone altered rock quartz vein type gold ore which means gold is mainly concentrated in quartz veins.We studird the genesis of the gold ore and find that the metallogenic fluid moves up through the tectonic fissure and extract the metallogenic material from surrounding rocks.The fracture structure provides the sedimentation space for the ore containing solution,and the gold ore bodies was eventually formed. |
