摘　　要：承德市位于华北地台北缘金银多金属成矿带东段,是河北省重要的金属矿产基地,目前探明的铜铅锌矿床达20余处,尤其近十年来,通过地质大调查项目的实施,相继发现了黑山铁矿、小寺沟含矿岩体外围的金银矿及云雾沟银多金属矿床等。文章在综合分析研究前人科研资料和找矿成果的基础上,归纳总结了铜铅锌成矿地质条件和找矿标志,认为本区成矿地质条件优越,矿化集中区有利部位物化探异常清晰,找矿标志明显,显示出铜铅锌矿产具有良好的找矿前景。Chengde, located in the eastern gold silver poly-metallic ore belt at north margin of the North China plat- form is the important metal mineral resource base. More than twenty copper-lead,zinc ore deposits have been discov- ered. Especially, Heishan iron deposit, gold-silver deposits in surroundings of Xiaoshigou ore-bearing intrusive body and Yubwugou Ag-polymetallic deposit etc. have been located through completion of the general geological investiga- tion projects. On the basis of comprehensive analysis of former researches and explorations, this paper summarizes metallogenic condition of copper-lead-,zinc deposit and the exploration marks and points out that Chengde area is supe- rior in metallogenic condition and target area in the clustered mineralization area is is marked with clear geophysical and geochemical anomly and exploration marks thus is potential for further exploration of Cu, Pb and Zn deposits.
