为寻找哈图齐Ⅱ金矿深部隐伏矿体，研究了该矿成矿特征和主要控矿构造的空间展布规律，发现矿区内多数矿脉集中分布于不完整褶皱的核部及包古图组C1b 1层中；断裂构造控矿作用明显，矿脉多发育在各级断裂的下盘或较大型断裂带内，控矿断裂有向下断续延伸的趋势，且规模未显著缩小。分析矿区内雁列式或串珠状盲矿体原生晕的分带性，发现该矿深部矿脉群的原生晕具前缘晕和尾晕共存的叠加结构。该特征是哈图齐Ⅱ金矿进行深部隐伏矿体找矿预测和评价的重要依据。

In order to prospect for deep concealed ore bodies in Hatu QiⅡgold deposit,studying on ore-forming charac-teristics and spatial distribution pattern of main ore-controlling structures in this gold deposit are conducted.We find that most veins distributed together in the core of the incomplete fold and C1b-1 layer of Baogutu formation and that gold ore bodies are obviously controlled by the faults and the veins developed in the footwall of all scales of faults and in larger fault belts.The ore-controlling faults have a downward trend of intermittent extension,and the scales have not significant-ly reduced.Analysis on zoning of primary halo of the echelon or beaded concealed orebody showed that primary halos of deep vein group have superimposed structure of front halo and tail halo coexisting. These features are considered an im-portant basis for prospecting prediction and evaluation to deep concealed ore in Hatu QiⅡgold deposit.
