| 摘 要： | 分同火山作用期和后火山作用期间述了北山地区古生代海相火山岩中铜－多金属成矿作用的构造背景。对同火山作用期的构造背景进行了重点探讨，认为它是大陆型地壳隆升及其后的裂陷环境，而不是大洋型地壳及其俯冲－碰撞环境。

THE GEOTECTONIC BACKGROUND FOR COPPERPOLYMETALLIC MINERALIZATION IN MARINE VOLCANIC ROCKS,BEISHAN AREA |
| |
| Abstract: | The geotectonic background for copper-polymetallic mineralization in marine volcanic rocks of Paleozoic era,Beishan area,is expounde respectively according to synvolcanic and postvolcanic stages. The author deems that the geotectonic background of synvolcanic stage was the continental crust upliftsing and following riftings,and was not oceanic crust and its subdution-collision. |

| Keywords: | marine volcanic rock crustal type geotectonic background synvolcanic stage postvolcanic stage |
