摘要
中铁目勒金矿地处中祁连陆块北缘成矿带,有一定的找矿潜力。通过对矿区地层、构造、岩浆岩、围岩蚀变特征进行研究,可知控矿因素为构造及岩体控制。区内含金岩石矿化蚀变现象在地表上形成醒目的黄色条带,构造蚀变带内岩石破碎,蚀变较强,金矿化出现的较强,是重要找矿标志。金矿化体主要赋存于加里东晚期侵入的碎裂状二长花岗岩及碎裂状斜长花岗岩岩体内。
The Zhongtiemule gold deposit is located in the metallogenic belt of the northern margin of the Middle Qilian Block,and has certain prospecting potential.By studying the alteration characteristics of strata,structures,magmatic rocks and wall rocks in the mining area,it can be concluded that the ore-controlling factors are structure and rock mass control.The mineralization and alteration of gold-bearing rocks in the area form striking yellow strips on the surface.The rock in the structural alteration zone is broken and altered strongly.The occurrence of gold mineralization is strong,which is an important indicator for prospecting.The gold mineralization bodies mainly occur in the intrusive cataclastic monzonitic granite and cataclastic plagioclase granite bodies in the late Caledonian period.
