岗讲铜矿区位于冈底斯斑岩铜矿带东段,是西藏尼木地区大型斑岩铜矿区之一。岗讲铜矿区包括岗讲、白容铜矿床和夏庆、渡布曲、绒岗蒙铜矿点。区内含矿斑岩体显示多期次复式岩体特征,铜钼矿化与钾硅化蚀变关系密切。后期断裂构造对含矿岩体具明显破坏作用,对矿床剥蚀程度也造成影响,初步认为岗讲矿床比白容矿床受剥蚀程度浅,其“环状”矿体中心的流纹-英安斑岩之下尚有较大的找矿潜力。
Kong said that the copper mine is located in the eastern part of the Gangdese porphyry copper belt and is one of the large-scale porphyry copper mines in the Niam area of Tibet. Gang speak of copper mining area, including posts say, Bai Rong copper deposits and Xiaqing, Du cloth song, velvet mound copper point. The ore-bearing porphyry bodies in the area show the characteristics of multi-stage complex rock mass, and the relationship between copper-molybdenum mineralization and potash-silicification alteration is closely related. The post-fault structure has a significant damage to the ore-bearing rocks and also affects the degree of denudation. It is preliminarily believed that the Gaoyu deposit is denser than that of the Bai-capacity deposit, and the riblet- Under the porphyry there is still a larger prospecting potential.
