中文摘要:
      团结峰铅锌矿床位于林济塘(陆缘盆地)Fe-Pb-Zn-Cu-Au-Mo-石膏矿带内,是近几年来新发现的铅锌矿床之一。本次研究在野外地质调查、探矿工程验证以及室内岩矿鉴定的基础上,查明该矿床含矿岩层受控于中侏罗统龙山组下段灰岩,矿体的分布明显受层理及层间破碎带等控制,产状呈层状、似层状,与早期构造及岩浆活动无明显关系;分析了含矿热液的形成、运移及铅锌硫化物的沉淀机制,初步建立其成矿模式。综合分析认为该矿床属层控密西西比河谷型(MVT)铅锌矿床,区域上同类型矿床具较大找矿潜力。
英文摘要:
      The Tuanjiefeng lead-zinc deposit located in Linjitang (epicontinental basin) Fe-Pb-Zn-Cu-Au-Mo-gypsum metallogenic belt, is one of the lead-zinc deposit found in recent years. On the basis of field geological survey, prospecting engineering verification and indoor mineral identification, the geological characteristics and metallogenic conditions and main controlling factors were analyzed. The result shows that the ore-bearing strata is controlled by middle Jurassic Longshan limestone group, the spatial distribution of ore bodies is obviously controlled by bedding and interlayer fracture zone in forms of layered and stratoid. There is not obvious relationship with the early tectonic and magmatic activities. Meanwhile, the formation, ore fluid migration, and precipitation mechanism of lead and zinc sulfide were analyzed, and the metallogenic model was established. The comprehensive analysis shows that the Pb-Zn deposit belongs to strata bound type Mississippi Valley-type (MVT). There is great potential for the same type deposit in the region.
