| 摘 要： | 罗家岭金矿受俯冲断裂带控制，并沿俯冲断裂带上盘分布，矿体定位在俯冲断裂带南侧2～4km的垂直距离内；近SN向含金构造破碎带是金矿体的主要容矿构造；两组韧性剪切带的交汇处是金矿化的有利部位；构造-岩浆活动对金矿体的形成有重要的控制作用。 |

| Abstract: | The gold deposit in Luojialing is controlled by faults in subducted zone and it distributes on the hanging wall of the fault. Investigation shows that the ore body is located at 2~4 km south in straight distance away from the fault. The ore body's host structure is a SN direction gold-bearing fractured zone. The zone of convergence of two ductile shear belts is believed to be the beneficial position of gold mineralization. All these indicate that the formation of the gold ore body is controlled to a great extent by the structure-magam activities. |
