金场沟铜钼、金矿成(控)矿条件分析与成矿规律

Ore control conditions and metallogenic regulation of Jinchanggou copper-molybdenum deposit

通过对矿区地层条件、构造条件和次火山侵入岩条件调查研究,平行敦密断裂的金场沟断裂(带)控制着次火山侵入岩和其中的角砾岩筒构造的分布,而角砾岩筒构造直接控制着铜钼矿的产出。其中铜钼矿化与花岗闪长斑岩有关,外围金银矿化与石英闪长岩有关。同时总结了成矿规律与进一步找矿方向。

Jinchanggou is located in the northern part of Taipingling gold and polymetallic metallogenic belt.Based on the comprehensive analysis and study of the stratigraphic condition,tectonic condition and sub-volcanic condition,it is considered that the distribution of sub-volcanic in trusive rocks and breccias pipe structure are controlled by the Jinchanggou faulted zone of the Dunmi parallel fault,and the output of copper and is directly controlled by breccias pipe structure.The copper and molybdenum mineralization is closely relative to quartz diorite.Meanwhile,summarized metallogenic regularity and the futher prospection direction.
