摘　　要：为指导银山矿田其它四个区段深部找矿,通过地质学和同位素年代学的分析方法,总结了银山铜铅锌矿九区北山区深部矿床特征,该矿床是银山背斜格架下的中生代陆相火山-次火山岩浆期后中低温热液矿床。此次九区北山区深部详查成果是银山矿田深部延伸新增资源储量,探明122b+332+333矿石量7 232.73万t,主矿产铜金属量52.70万t、共生铅8.79万t、共生锌16.74万t、伴生金41.72 t、伴生银1 026.09 t、伴生硫470.77万t。银山矿田其它四个区段深部和九区北山区-1 200 m标高以下仍有极好的找矿前景,同时也丰富了人们对"银山式铜铅锌多金属矿床"成矿地质特征的认识。Through the analysis of geological and isotope chronology methods,The characteristics of deep copperlead-zinc ore deposit of nine districts and the north mountain in Yinshan which is the Mesozoic volcano-subvolcano magmatic medium low temperature hydrothermal of continental deposit under the framework of Yinshan anticline for guiding prospecting other four section deep in Yinshan ore field.The survey results which deep in nine districts and the north mountain is additional resources reserves of extending Yinshan ore field,proven 72 327300 tons ore capacity of 122 b ＋ 332 ＋ 333,the main mineral copper amount of metal 527000 tons,symbiotic lead 87900 t and symbiotic zinc 167400 t,41.72 t of associated gold,1 026.09 t of associated silver,with accompanying sulfur 4707700 tons.The conclusion piont out that there is still good ore prospects in the other four sections and nine districts and the north mountain of Yinshan ore field below the elevation of-1200 meters and enrich geological unstanding of the“geological metallogenic copper-lead-zinc polymetallic deposit like Yinshan”.
