海底山脈、海底火山、裂谷、大洋中脊等等，構成了豐富的海底世界。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 )
