中文摘要:
      蒿坪沟银金铅锌矿床位于河南省西部熊耳山有色贵金属重点成矿区,华北地台南缘与秦岭造山带交接部位,出露地层主要为新太古界太华岩群高级变质岩系,属于薄脉状构造破碎带蚀变岩型矿床,矿体严格受断裂构造带控制。含矿构造破碎带以北东向为主,其次为近南北向。该矿床形成于晚侏罗世至早白垩世中国东部构造体制大转换(主压应力由近南北向转向北西—南东向)时期。北西—南东向主压应力场利用、改造已经形成的近南北向主压应力场产生的断裂构造体系,产生新的断裂构造组合,提供导矿和容矿空间。文章提出该矿区找矿潜力很大,并指出了下步找矿的重点部位和方向。
英文摘要:
      The Haopinggou Pb-Zn-Ag-Au deposit is located in the key metallogenic belt of non-ferrous metallic deposits in western Hennan Province Xiong,er Mountain, occurred at the jointed section of the south China platform and Qinling orogenic belt. The outcropped host strata is the Archean high metamorphic rocks of Taihua group. The deposit is a thin vein structural-controlled altered type Pb-Zn-Ag deposit, the ore bodies are controlled by faults. The fracture zone mainly strikes NE-trendign, secondly SN-trending. The deposit was formed in the early stage of tectonic system transformation of East China during the period of from late Jurassic to early Cretaceous age. The NW-SE trending tectonic stress field utilize ade remakes the fault structure system formed by the previuous nearly NS-trending tectonic stress field, formation a the new fault system. Based on the study, it pointed out that there is great prospecting potential for prospecting in the deposit area, and prospecting direction and the key prospecting targets were proposed based on the structural analysis result.
