In the light of tectonic evolution stage and metallogenesis , these metallogenic system ( assemblage ) could be classified as follows : ( 1 ) the pre - divergent metallogenic system in the southwest margin of north china paleocontinent in the archean - meso proterozoic : dongdashan iron , jinchuan nickel - copper . ( 2 ) the divergent metallogenic system in the northern margin of the qaidam paleoplate in the middle - late proterozoic : huashugou - liugouxia iron . ( 3 ) the metallogenic system in the active margin in the early paleozoic : the metallogenic assemblage in the island arc - rift in the early stage ( baiyinchang - qingshuigou copper - polymetallic ) ; the metallogenic assemblage in island arc in the middle - late stage ( honggou - jiaolongzhang copper - polymetallic ) ; the back - arc extensional basin ( zhuzhuiyaba - jiugequan - shijuli copper ) ; the metallogenic assemblage in connection with subduction and magmatic - hydatogenesis ( taergou - xiaoliugou wolfram ; huashugou - liugouxia copper ; dadonggou - diaodaban lead - zinc ) ; the metallogenic assemblage is related to the oceanic crustal shards ( dadaoerji chromite ; yushigou chromite ) . ( 4 ) the metallogenic system has something to do with collision - type orogeny : the metallogenic assemblage in foreland basin ( tianlu copper ) ; the metallogenic assemblage with the intracontinental orogeny and ductile shear ( hanshan - yingzhuishan gold ) 根據構造發展階段和成礦作用特點，確定本區成礦系統及組合如下： ( 1 )華北板塊西南邊緣太古宙中元古代裂解期前成礦系統：東大山鐵成礦組合，金川鎳銅成礦組合； ( 2 )柴達木板塊北緣中、新元古代裂解成礦系統：樺樹溝柳溝峽鐵成礦組合； ( 3 )加里東期活動大陸邊緣成礦系統：早期島弧裂谷成礦組合(白銀廠清水溝銅及多金屬成礦組合) ，中、晚期島弧成礦組合(紅溝蛟龍掌銅及多金屬成礦組合) ，弧后擴張盆地成礦組合(豬咀啞巴九個泉石居里銅及多金屬成礦組合) ，與俯沖作用有關的巖漿熱液成礦組合(塔爾溝小柳溝鎢成礦組合，樺樹溝柳溝峽銅成礦組合，大東溝吊大坂鉛鋅成礦組合) ，洋殼殘片成礦組合(大道爾吉鉻成礦組合，玉石溝鉻成礦組合) ； ( 4 )碰撞造山成礦系統：前陸盆地成礦組合(天鹿銅成礦組合) ，陸內造山韌性剪切成礦組合(寒山鷹咀山金成礦組合) 。 |
