摘要
通过开展阿尔金东段和祁连西段岩金矿床之间对比研究,分析二者之间的关联,发现两个成矿带内部金矿成矿物质来源、成矿时代、控矿因素、矿床类型、找矿标志和围岩蚀变等存在相似性和可对比性,特别是阿尔金断裂及其次生断裂带对金矿有着明显控制作用,在此基础上总结了研究区金矿成矿规律和主要找矿标志。通过与祁连西段金矿床对比研究,说明阿尔金山东段金矿进一步找矿潜力较大。
Through systematic comparative study of gold deposits in the eastern Altun and western Qilian,the correlation between the two metallogenic belts is analyzed.It is found that the source of ore-forming materials,metallogenic epoch,ore-controlling factors and prospecting indicators of gold deposits in the two metallogenic belts are similar and comparable.Especially Aerjin fault and its secondary fault system is the key to the control of gold deposits.On the basis of this,the metallogenic regularity and main prospecting indicators of gold deposits in the study area are systematically summarized,providing effective basis for regional prospecting.At the same time,through the comparative study with the gold deposits in the western Qilian,it is found that the gold deposits in the eastern Altun have great potential for further prospecting.
