甘肃郝泉沟金矿床地质特征及找矿标志浅析

Geological Features and Prospecting Signs of HaoquangouGold Deposit, Gansu Province

郝泉沟金矿床位于甘肃著名的白银厂矿田外围之南西侧,属北祁连山加里东褶皱带之东段,区域构造样式组合复杂,具有良好的找矿潜力。区内Au、Ag、Cu、Pb、Zn矿化线索分布广泛,显示出优越的成矿地质背景条件。本文以郝泉沟金矿床为研究对象,总结了区域地质背景、矿区地质特征,认为郝泉沟金矿床严格受控于岩体内外接触带和断裂破碎带的控制,并提出了郝泉沟地区找矿标志,为进一步找矿勘查工作提供参考。

Haoquangou Gold bed in Gansu province,The famous silver mines in the west side of the southern part of the Caledonian Fold belt in the east of the North Qilian mountains,regional structural style combination complex,with good prospecting potential.The mineralization clues of Au,Ag,Cu,Pb and Zn in the region are widely distributed,which shows superior metallogenic geological background conditions.Taking the Haoquangou gold deposit as the research object,this paper summarizes the regional geological background and geological characteristics of the mining area,and holds that the Haoquangou gold deposit is controlled strictly in the inner and outer contact zone and fracture Zone of the rock,and puts forward the prospecting signs in the Haoquangou ditch area,which provides reference for the further prospecting Work.
