西藏拿若铜(金)矿床深部找矿潜力分析

Analysis on the resource potential in depth of Naruo Copper(gold) Deposit in Tibet

拿若铜矿是较为典型的斑岩型铜矿床,是多龙矿集区的重要组成部分。拿若矿床在近两年开始进行商业性勘查之后,矿床资源量有了突破性增长,但是深部找矿潜力问题还需要解决。笔者对矿区进行了详细的野外地质调查和钻孔科研编录,对矿床有了更详尽的认识。因此,在钻孔岩芯基本元素分析数据和野外工作的基础上,结合前人资料对矿床深部找矿前景进行了探讨,认为在隐爆角砾岩筒和岩体发育的ZK0001孔附近有较好的找矿潜力。

The Naruo Copper（gold）Deposit is a typical porphyry deposit and an important part of Duolong ore concentration area.There is a rapid growth in quantity of resource after recently commercial exploration in the deposit,but prospecting potential in depth is a problem which needs to be resolved in time.This paper has engaged in the detailed geological survey and scientific drilling logging and knows the deposit better.This paper discusses prospecting potential in depth and considers that there is preferable prospecting potential near the crypto explosive breccias pipe and ZK0001 drill based on basic elemental analysis,field work and predecessor data.
