摘　　要：陕西白河黄石板铅锌矿位于南秦岭镇(安)旬(阳)古生代沉积盆地南缘东部,区内已发现并探明的数量众多的铅锌矿床(点)多数产自泥盆系沉积盆地中,仅个别产自志留系。以志留系具代表性的黄石板铅锌矿床为研究对象,结合研究区以往的铅锌矿研究成果,认为志留系铅锌矿床主要产自梅子垭组粉砂质千枚岩与热水沉积岩接触部位的硅钙面,受区域断裂及次级断裂控制明显,热水沉积形成的钠长石岩为铅锌的富集提供了条件。通过对研究区地质特征、控矿条件及找矿标志的初步分析,为研究区寻找同类型铅锌矿床提供参考。The Huangshiban lead-zinc deposit in Baihe County,Shaanxi Province is located in the east of the southern margin of the Zhen′an-Xunyang Paleozoic sedimentary basin,South Qinling.A large number of lead-zinc deposits(occurrences)have been discovered and proved in the study area,most of which produced in Devonian sedimentary basin,only a few produced in Silurian strata.Based on the representative Silurian Huangshiban Pb-Zn deposit,this paper learns from related previous research in the study area,and believes that the Silurian Pb-Zn deposit mainly comes from the silicon-calcium surface where silty melite of the Meiziya Formation meets hydrothermal sedimentary rock,and is obviously controlled by regional fracture and secondary fracture.Albite rocks formed by hydrothermal deposition provide conditions for Pb and Zn enrichment.Through the preliminary analysis of geological characteristics,ore-controlling conditions and prospecting marks of the study area,it provides some reference for searching the same type of lead-zinc deposits in the study area.
