| 摘 要： | 阿加隆洼金矿是近年来在甘孜-理塘断裂带发现的一个中型低温热液型金矿床.区内围岩蚀变发育广泛,具多期次,蚀变类型主要有硅化、碳酸盐化、黄铁矿化、毒砂化、绿泥石化等.文章在介绍阿加隆洼金矿床区域地质背景、矿床特征、矿体地质特征的基础上,着重对矿床的围岩蚀变特征进行了较为深入地论述,并分析了该矿床的成矿地质条件.认为矿化蚀变岩带与金矿化关系密切,尤其与硅化、碳酸岩化、黄铁矿化最为密切,并且含矿热液在迁移过程中,与围岩发生的流体 - 岩石反应,造成金的沉淀、富集,最终形成金矿床. |

| Abstract: | Ajialongwa gold deposit,discovered in the Ganzi-Litang fault zone,is a middle scale epithermal gold deposits.Wallrock alterations are distributed widely in the area.Wallrock alterations include silicification,pyritization,carbonation and arsenopyritezation,and chloritization.Based on regional geological setting,deposit characteristics,geologic features of deposit,wallrock alterations and ore-forming geological conditions are summed up.It is considered that alterations zones,particularly silicification,carbo... |
