小南沟银铅矿区内的矿脉严格受熊耳山变质核杂岩构造及其滑脱拆离断层控制。其控矿机制主要有三种，即拆离断层面型控矿、拆离断层下盘次级断裂控矿、熊耳群中的犁式正断层控矿。通过对这几种控矿机制的分析，了解了熊耳山地区伸展构造控矿模式。
小南溝銀鉛礦區內的礦脈嚴格受熊耳山變質覈雜巖構造及其滑脫拆離斷層控製。其控礦機製主要有三種，即拆離斷層麵型控礦、拆離斷層下盤次級斷裂控礦、熊耳群中的犛式正斷層控礦。通過對這幾種控礦機製的分析，瞭解瞭熊耳山地區伸展構造控礦模式。

The silver-lead veins in Xiaonangou are strictly con-trolled by Xiong'ershan metamorphic core complexs and detachment fault.There are three main types of the ore controlling mechanism, which are the detachment fault type,the detachment secondary fault footwall and the Xiong'er group of Listric fault.Through the analysis of these different kinds of ore controlling mechanism,we know the ore controlling model of extensional tectonics in Xiong'ershan.
