摘　　要：以产于黄岗—甘珠尔庙成矿带的铅锌矿产为预测矿种,以铅锌矿矿床为目标物,较系统地分析了地层、岩浆岩等地质条件与铅锌矿产的关系,查明各种地质条件对铅锌矿产的控制作用与控制方式。二叠系与铅锌成矿在空间分布和物质成分方面有着密切的联系,锰质钙铁辉石夕卡岩及火山沉积岩为铅锌成矿提供物质来源;燕山期岩浆侵入活动形成的中酸性侵入体为有利岩体;成矿带内多组方向断裂的交汇部位是矿化富集区,使得矿床以北东成带、东西成行,各矿床之间具有等距离的特点进行分布。由地质信息、地球化学信息及矿化信息构成的矿床级别的综合信息找矿模型,为成矿带内铅锌矿产预测提供了理论依据。Taking the lead-zinc deposit of Huanggang-Ganzhuermiao Metallogenic Belt as a predicted mine,this paper systematically analyzed the relationships between geological conditions including strata and magmatic rocks,etc.and lead-zinc deposits,and found out the control action and manner of geological conditions on lead-zinc deposit.The lead-zinc mineralization has a close relationship with the Permian in spatial distribution and content compositions.Manganese calcium pyroxene skarn and volcanic sedimentary rocks provide material for lead-zinc deposit.The beneficial rocks are Yanshanian acid intrusive bodies.In the metallogenic belt,the concentrated mineralization area is the intersection of multiple parts of fractures.The differently striking faults make deposits form a NE zone and an EW row,and the deposits distribute with equal intervals.Finally,we established a comprehensive prospecting model for lead-zinc deposit,which consists of geological,geochemical and mineralization information and provides the theoretical basis for predicting the lead-zinc deposit within the metallogenic belt.
