| 摘 要： | 对冀北１７个银矿床地质调查和５个大一中型银矿床地质、地球化学剖析研究基础上，从银矿床产出的区域地质、矿床地质、控制地质条件、围岩蚀变、矿石类型、成矿机理、成矿时代和成矿物质演化上，确定了冀北银矿床有３个成矿系列，８种矿床类型。提出牛圈子为火山喷气－热泉型银矿床；蔡家营为古喷气－热水沉积变质－热液叠加型铅锌银矿床；银冶岭为层控－热液叠加型铅锌银矿床的新认识，建立了冀北银矿床成矿模式和地史演化的区域成

| Abstract: | The author investigated 17 Ag deposits of which 5 are large medium size on basis of geology, geochemistry, regional geological setting, ore controlling conditions, wallrock alterations, ore types, metallogenic mechanism, ore formaion stages, metallogenic evolution recognizing three metallogenic series and 8 types of Ag ore deposit. Niujuanzi is a volcanic exhalation hot spring Ag deposit; Caijiaying, a exhalation hot water precipitation hydrothermal fluid overprint Pb, Zn, Ag deposit; Yinyeling, a stratabound hydrothermal fluid overprint Pb, Zn, Ag deposit. Based on the results metallogenic model and regional geohistory evolutional metallogenic model of the deposits are established and the ore searchging directions are pointed out. |
