河南熊耳山地区的金矿大多产于ＮＥ向和近Ｅ－Ｗ向断裂中．近年来发现的小南沟金矿受控于近Ｓ－Ｎ向断裂，开拓了该地区金矿找矿的新思路．研究表明，近Ｓ－Ｎ向的控矿断裂为ＮＮＷ向与ＮＥ向一组共轭断裂的复合成因，是在Ｅ－Ｗ向基底断裂的基础上发育形成的，成矿作用与区域成矿具有一致性．总结出ＮＥ向断裂有利成矿的断裂走向勘探标志，指出小南沟金矿的外围仍有良好的找矿条件，ＮＮＷ向、ＮＥ向与ＮＷＷ向断裂构造交汇部位有利成矿．小南沟主矿体存在向北的迅速侧伏，侧伏的原因与Ｅ－Ｗ向断层北倾以及ＮＮＷ与ＮＥ向断层交汇线的向北侧伏有关．
Most gold mines in Xiong’ershan area of Henan Province are produced in NE and near E-W faults. The Xiaonangou gold deposit discovered in recent years is controlled by near-S-N faults and opens up new ideas for gold prospecting in the area. The results show that the ore-controlling faults in the near S-N direction are the complex genesis of a group of conjugate faults between NNW and NE and are formed on the basis of the E-W fracture to the basement. The mineralization and regional mineralization have consistency. It is concluded that the exploration direction of the NE-trending favorable ore-forming fault is summarized. It is pointed out that the outer periphery of the Xiaonangou gold deposit is still well prospecting, and favorable mineralization is formed at the junction of NNW direction, NE direction and NWW fault structure. The main ore body of Xiaonanggou exists a rapid lateral voltage to the north. The reason of the lateral volt is related to the northward fault of E-W fault and the northward volt fault of NNW and NE fault.
